Finance Department Secure Document Email Virus: How the Fake PDF Installs a RAT

By Thomas Orsolya6 min read

A confidential disbursement document from the Finance Department sounds like something an employee cannot ignore. That is exactly why this malicious email uses an internal-business disguise instead of an obvious prize or payment lure.

The document is fake. Its Open Document button leads to a counterfeit reader-update page that downloads a ZIP archive containing a trojanized remote-access tool. Running it can give criminals quiet control of the computer.

Fake Finance Department secure document email delivering remote access malware
The campaign turns a believable internal document notification into a download chain that installs remote-access malware.

Overview

The Finance Department Secure Document email is a confirmed malspam campaign, not a legitimate file-sharing notification. It claims that a confidential disbursement agreement has been shared through a service called Resursas Secure Document Portal.

The message may address the recipient by name, show a preview for a file such as [name]_Disbursement_Agreement.pdf, and describe it as a small Adobe PDF document. A prominent Open Document button provides the next step.

That button does not open a PDF. It leads to fp.qdiuly[.]net, where a page designed to resemble a software download site claims that the visitor’s document reader is outdated. The site then starts downloading Adobe_Acrobat_Reader_en_Install.zip.

Inside the archive is a modified build of ScreenConnect. ScreenConnect is a legitimate remote-support product, but the version distributed in this campaign has been configured as a remote access trojan. The legitimate developer and Adobe are not involved in the attack.

Once executed, the program connects the computer to infrastructure controlled by criminals. They may view the screen, browse or copy files, record keystrokes, steal saved passwords and install additional malware. Because remote-support software is designed to operate quietly, the compromise may not produce an obvious warning.

This is more dangerous than a simple fake-login page. The attacker is not collecting one password through a form; the goal is to establish an ongoing foothold inside the Windows computer and use that access for surveillance, credential theft or a larger intrusion.

  • Pretends to be an internal Finance Department notification
  • Shows a convincing confidential PDF preview
  • Redirects to a domain unrelated to the employer or document service
  • Invents an outdated-reader problem to justify a download
  • Distributes a ZIP archive containing trojanized remote-access software

Is the Finance Department Secure Document Email Legitimate?

No. This specific message is malicious. A genuine internal document should open through the company’s known collaboration platform, document system or employee portal. It should not require a software update from fp.qdiuly.net or another unfamiliar domain.

The presence of a real employee name, a PDF icon or a familiar finance term does not validate the email. Those details can be copied from public company pages, breached mailboxes or earlier business correspondence.

How the Finance Department Document Malware Attack Works

Step 1: The email creates a believable workplace task

The recipient is told that the Finance Department shared a confidential disbursement document. The request feels routine enough to lower suspicion but important enough to demand attention.

Step 2: A PDF preview makes the message feel specific

The email displays the recipient’s name, a professional filename and a file-size label. These visual details make a mass-distributed lure resemble a real document notification.

Step 3: Open Document leads away from the company

The button directs the browser to an unrelated external website. The destination is controlled or abused by the campaign and has no authority to deliver an internal finance file.

Step 4: A fake update page starts a ZIP download

Instead of showing the promised PDF, the page claims that document software is outdated. The unexpected update explains why an archive is downloaded and encourages the victim to run it.

Step 5: Trojanized ScreenConnect establishes remote access

Launching the installer activates a maliciously configured copy of a legitimate support tool. It connects the computer to the attacker’s server without providing the finance document.

Step 6: The attacker explores the compromised computer

The operator can watch activity, retrieve files, capture credentials and deploy additional payloads. The access can also be used to move toward company accounts or other devices.

What the Remote Access Trojan Can Do

A trojanized remote-support program can give the operator capabilities similar to someone sitting at the computer. The exact actions depend on the attacker’s objectives and the permissions available to the infected account.

  • View the desktop and monitor activity in real time
  • Browse, copy, upload or delete local and network-accessible files
  • Capture keystrokes and passwords entered after infection
  • Search browsers and applications for stored credentials
  • Install information stealers, ransomware or other malware
  • Use the compromised machine to impersonate the employee

Red Flags in the Fake Secure Document Email

  • You were not expecting a disbursement agreement
  • The sender address does not match your employer’s real domain
  • The named document portal is not a service your company normally uses
  • The button opens fp.qdiuly[.]net or another unrelated host
  • A PDF suddenly requires a ZIP-based reader update
  • The download begins before the promised document is displayed

What to Do If You Received the Email

  1. Do not click Open Document or download the archive
  2. Contact the Finance Department through a known phone number or internal chat
  3. Report the message to the IT or security team as a suspected malware email
  4. Preserve the email for investigation if your organization requests it
  5. Delete the message after it has been reported

What to Do If You Interacted With the Download

If you clicked the link but downloaded nothing

Close the page and report the email. Clear the site’s downloads and cookies if necessary. Merely viewing the page does not install the RAT, but do not accept notifications or run anything it offers.

If the ZIP downloaded but you did not open it

Delete the archive from the Downloads folder and empty the Recycle Bin. Run a security scan for reassurance and tell the IT team where the file originated.

If you extracted or ran the installer

Treat the computer as compromised. Disconnect it from Wi-Fi and Ethernet to interrupt remote access, but do not power it off if a company incident-response team needs to preserve evidence. Contact IT immediately from another device.

Do not sign in to email, banking or company services on the affected computer. Change important passwords from a separate clean device, beginning with email and business accounts, and revoke active sessions where possible.

Scan and Remove the Malware From Windows

A full security scan is necessary because removing the downloaded ZIP does not remove a program that has already run. Additional payloads or persistence settings may remain even if ScreenConnect is no longer visible.

If you suspect your computer is infected with malware — slow performance, pop-ups, redirects, or programs you don’t recognize — follow the free step-by-step removal guide below to find and remove it.

Remove Malware from Windows [Step-by-Step Guide]

Before you start: this guide may look long, but that’s only because we’ve broken everything down into clear, detailed steps that anyone can follow — no technical skills needed, and every tool we use is free.
Please follow the steps in order. If you get stuck or have doubts at any point, stop and ask for help in our free support forum — our team will guide you personally.
To remove Trojans and other malware from your computer, follow these steps:

STEP 1: Uninstall malicious programs from Windows

First, we’ll manually check your computer for unknown or malicious programs. Adware and browser hijackers often have a working uninstall entry — removing them this way takes care of the easy part before we run the scanners.

  1. Open the Settings app

    Press Windows + I on your keyboard to open Settings. Alternatively, right-click the Start button and select “Settings” from the menu.

    Windows 11 taskbar, left end: the Start button with the Windows logo is highlighted (1), next to the Search box
  2. Go to “Installed apps”

    In the Settings window, click “Apps” in the sidebar, then select “Installed apps“.

    Windows 11 Settings with Apps selected in the sidebar (1) and the Installed apps page open, its Apps › Installed apps title highlighted (2); account details and app list blurred
  3. Find and uninstall the malicious program

    Scroll through the list of installed apps and look for anything suspicious — a program you don’t remember installing, or one with a strange or generic name.
    Quick tip: click “Sort by” and choose “Date installed“. Malware is usually one of the most recently installed programs, so it will appear near the top.
    When you find the malicious program, click the three dots next to it and select “Uninstall“.

    Windows 11 Installed apps page: the Sort by menu is highlighted (1) and the three-dot More options button next to the first app (2); app names are blurred
    Didn’t find any suspicious programs? That’s fine — not all infections install visible apps. Just continue with the next step in this guide.
  4. Complete the uninstall

    Confirm by clicking Uninstall in the message box, then follow the remaining prompts.
    Read each prompt carefully — some malicious programs use confusing wording or pre-ticked boxes hoping you’ll click through without looking.

    Windows 11 Confirm Uninstall

Windows 10 reached the end of support on October 14, 2025, so it no longer gets regular security updates. If your PC can run it, upgrade to Windows 11. If it can’t, enroll in Microsoft’s Extended Security Updates program.
  1. Open the Settings app

    Press Windows + I on your keyboard to open Settings. Alternatively, click the Start button on the taskbar and select “Settings” (the gear icon).
    Windows 10: Click the Start button then click on Settings

  2. Click on “Apps”

    In the “Windows Settings” window, click “Apps“. The “Apps & Features” section should open by default — if it doesn’t, select it from the list on the left.

    Windows 10: Click on Apps

  3. Find and uninstall the malicious program

    Scroll through the list of installed apps and look for anything suspicious — a program you don’t remember installing, or one with a strange or generic name.
    Quick tip: click “Sort by” and choose “Install date“. Malware is usually one of the most recently installed programs, so it will appear near the top.
    When you find the malicious program, click on it and select “Uninstall“.

    Windows 10: Uninstall malware from Windows

    Didn’t find any suspicious programs? That’s fine — not all infections install visible apps. Just continue with the next step in this guide.
  4. Complete the uninstall

    Confirm by clicking Uninstall in the message box, then follow the remaining prompts.
    Read each prompt carefully — some malicious programs use confusing wording or pre-ticked boxes hoping you’ll click through without looking.
    Windows 10: Complete the uninstall process

Is a stubborn program refusing to uninstall? Use Revo Uninstaller to force-remove it completely, including leftover files and registry entries.

With the malicious programs removed, you’re ready for the next step in this guide.

STEP 2: Reset browsers back to default settings

In this step, we will remove spam notifications,  malicious extensions, and change to default any settings that might have been changed by malware.
Please note that a Chrome or Edge reset turns off all your extensions, and a Firefox refresh removes them. Your bookmarks and favorites stay intact. For each browser that you have installed on your computer, please click on the browsers tab below and follow the displayed steps to reset that browser.

Reset Chrome for Windows to default settings

We will now reset your Chrome browser settings to their original defaults. This will reset your startup page, new tab page, search engine, and pinned tabs. It will also disable all extensions and clear temporary data like cookies. Your favorites, history, and saved passwords will not be cleared.

  1. Open the Chrome menu

    Open Google Chrome and click the three-dot (⋮) icon in the top-right corner.

    Click the three-dot menu icon in Chrome
  2. Open Chrome Settings

    Select Settings from the Chrome menu.

    Select Settings from the Chrome menu
  3. Select “Reset settings”

    Look at the menu on the left side of the Settings page. Scroll down and click Reset settings.

    Click Reset settings in the Chrome sidebar
  4. Restore Chrome’s original settings

    Click Restore settings to their original defaults.

    Choose Restore settings to their original defaults


  5. Confirm the Chrome reset

    A confirmation window will appear. Click Reset settings.

    This will:

    • Restore the default search engine, homepage, and new tab page
    • Reset startup pages and pinned tabs
    • Reset site permissions, such as notifications and pop-ups
    • Disable installed extensions
    • Clear temporary cookies and website data

    Don’t worry: Chrome will not delete your bookmarks, browsing history, or saved passwords. If you’re signed in to Chrome, the reset applies on all devices where you’re signed in.

    Restart Chrome and perform a test search. If your searches now open normally in Google, you can stop here.

    If searches are still redirected through shady domains complete the additional step below.

    Confirm the Chrome reset
  6. Remove persistent search hijacker data

    Only complete this step if the redirect continues after resetting Chrome.

    Some browser hijackers hide inside Chrome’s local search-engine database. A standard Chrome reset may not remove this database, which is why searches can continue to pass through shady sites.

    The following procedure creates a backup of the affected database and allows Chrome to build a new, clean version. This is safer and less disruptive than deleting the entire Chrome profile.

    First, prevent Chrome Sync from restoring the hijacked settings:

    1. Open a new Chrome tab.
    2. Copy the following address, paste it into Chrome’s address bar, and press Enter:
      chrome://settings/syncSetup/advanced

    3. Under Manage what you sync, select Customize sync.
    4. Turn off Settings and Extensions.
    5. You can leave Bookmarks and Passwords enabled so your important data remains synchronized.

    Note: Some newer Chrome versions may automatically redirect this address to the Google Account settings page. If that happens, locate the list of synchronized Chrome data and turn off Settings and Extensions there.

    Chrome Manage what you sync page at chrome://settings/syncSetup/advanced, with Customize sync selected and arrows pointing to the Settings and Extensions switches

    Now save anything you are working on and close every Chrome window.

    Run the cleanup command:

    1. Press the Windows key on your keyboard.
    2. Type PowerShell.
    3. Open Windows PowerShell. Administrator access is not required.
    4. Copy the entire command shown below.
    5. Right-click inside the PowerShell window to paste the command, then press Enter.
    6. If Windows warns you about pasting multiple lines, select the option to continue.

    $stamp = Get-Date -Format "yyyyMMdd-HHmmss"

    Get-Process chrome -ErrorAction SilentlyContinue |
    Stop-Process -Force

    $root = "$env:LOCALAPPDATA\Google\Chrome\User Data"

    if (Test-Path $root) {
    $profiles = Get-ChildItem $root -Directory |
    Where-Object {
    $_.Name -eq "Default" -or
    $_.Name -match "^Profile \d+$"
    }

    foreach ($profile in $profiles) {
    foreach ($name in @(
    "Web Data",
    "Web Data-journal",
    "Web Data-wal",
    "Web Data-shm"
    )) {
    $file = Join-Path $profile.FullName $name

    if (Test-Path $file) {
    $backup = "$file.search-hijacker-backup-$stamp"
    Move-Item -LiteralPath $file -Destination $backup
    Write-Host "Backup created: $backup"
    }
    }
    }
    }

    Write-Host ""
    Write-Host "Chrome search data has been cleaned."
    Write-Host "You can now reopen Chrome."

    Wait until PowerShell displays the following message:

    Chrome search data has been cleaned.
    You can now reopen Chrome.
    Windows PowerShell window after the cleanup command ran, showing the backup file names and the message Chrome search data has been cleaned

    Close PowerShell and reopen Google Chrome. Chrome will automatically create a clean search database for every local profile.

    Next, copy the following address, paste it into Chrome’s address bar, and press Enter:

    chrome://settings/searchEngines
    Chrome Manage search engines and site search page with Google (Default) highlighted (1) in the Search engines list

    Make sure Google is selected as the default search engine. Test several searches from the address bar and confirm that they no longer pass through shady search engines.

    Your important Chrome data is protected: the PowerShell cleanup does not remove bookmarks, saved passwords, browsing history, cookies, or installed extensions. However, it may reset locally stored Autofill addresses, payment cards saved only on this computer, and form suggestions.

    The original search database is not deleted. PowerShell renames it and adds search-hijacker-backup to its filename so it can be recovered if necessary.

    Keep Settings and Extensions synchronization disabled while testing Chrome. Do not enable every extension at once. Enable only the extensions you recognize, one at a time, and test Chrome after each one.

    Chrome Extensions page with the demo extension Example Coupon Helper switched off: its on/off switch (1), its Remove button (2) and the Safety Check card Review 1 extension that may be unsafe (3)

    If the redirect returns after enabling a particular extension, remove that extension immediately.

Reset Firefox for Windows to default settings

We will now reset your Firefox browser settings to their default. The reset feature fixes many issues by restoring Firefox to its factory default state while saving your essential information like bookmarks, passwords, web form auto-fill information, browsing history, and open tabs.

  1. Open the Firefox menu and click “Help and Report”

    Click the three horizontal lines in the top-right corner of Firefox to open the main menu, then select “Help and Report“.

    Firefox window, top-right corner: the Open application menu button (three horizontal lines) is highlighted (1), next to the extensions and account buttons and below the window controls
  2. Click “More troubleshooting information”

    In the Help and Report menu, click “More troubleshooting information“.

    Firefox Troubleshooting Information page (about:support) with its heading highlighted (1); the Give Firefox a tune up box is on the right
  3. Click “Refresh Firefox”

    On the “Troubleshooting Information” page, click the “Refresh Firefox” button in the “Give Firefox a tune up” box in the top-right area of the page.

    Firefox Troubleshooting Information page: the Refresh Firefox… button under Give Firefox a tune up is highlighted (1)
  4. Confirm the refresh

    In the confirmation window, click “Refresh Firefox” again. This removes extensions, themes, and customized settings — the usual hiding places for browser hijackers — while keeping your bookmarks, history, and saved passwords safe.

    Firefox Refresh Firefox to its default settings? confirmation window over the Troubleshooting Information page, with the red Refresh Firefox button highlighted (1)
  5. Click “Finish”

    Firefox will close, reset itself to default settings, and reopen with a window listing the information that was restored. Click “Finish“. Then test Firefox before you add back any extensions.

    About the “Old Firefox Data” folder: Firefox saves a copy of your old profile on your desktop. If something you need is missing after the reset, you can recover it from this folder. Otherwise, delete the folder — it contains sensitive data like passwords and cookies, and may also still hold the malicious files you just removed.

Reset Microsoft Edge to default settings

We will now reset your Microsoft Edge browser settings to their default. This will reset your startup page, new tab page, search engine, and pinned tabs. It will also disable all extensions and clear temporary data like cookies. Your favorites, history, and saved passwords will not be cleared.

Updated for Microsoft Edge on Windows 10 and Windows 11 — July 2026.

  1. Open the Edge menu and click “Settings”

    Open Microsoft Edge. In the top-right corner, click the three-dot (…) icon, then click Settings.

    Microsoft Edge Settings page, top part: the Settings heading is highlighted (1), with the Search settings box and the Most searched shortcuts beside it
  2. Prevent the unwanted settings from returning through Edge Sync

    If you are signed in to Microsoft Edge, a bad setting or extension may be stored in your Microsoft account and return after the reset.

    Copy the following address, paste it into the Edge address bar, and press Enter:

    edge://settings/profiles/sync

    On the Sync page, turn off these two options:

    • Settings
    • Extensions

    You can leave Favorites and Passwords turned on.

    If Edge says that sync is already off, simply continue to the next step.

    Important: Edge Sync settings are separate for each profile. If you use more than one Edge profile, switch to each affected profile and repeat this step.

    You do not need to sign out of your Microsoft account or delete the Edge profile.

  3. Open “Reset settings”

    In the left sidebar, click Reset settings.

    You can also open the reset page directly. Copy the following address, paste it into the Edge address bar, and press Enter:

    edge://settings/reset
    Microsoft Edge Settings with Reset settings highlighted in the left sidebar (1); the Reset settings page is open on the right
  4. Click “Restore settings to their default values”

    Click Restore settings to their default values.

    Microsoft Edge Reset settings page: the Restore settings to their default values row is highlighted (1)
  5. Confirm the reset

    In the confirmation dialog, click Reset.

    This resets the startup page, new tab page, search engine, and pinned tabs. It also disables all extensions and clears temporary site data, such as cookies.

    Don’t worry: your favorites, browsing history, and saved passwords will not be deleted.

  6. Check your extensions before turning them back on

    Copy the following address, paste it into the Edge address bar, and press Enter:

    edge://extensions

    Remove any extension you do not recognize or no longer use. Pay particular attention to extensions related to search, coupons, shopping, PDF conversion, browser protection, new tabs, or video downloading.

    Do not turn all extensions back on at the same time. Enable only the extensions you recognize and trust.

    Microsoft Edge Extensions page: the demo extension Example Coupon Helper under From other sources, with its Remove button (1) and its on/off switch, switched off (2)
  7. Select a trusted search engine

    Copy the following address, paste it into the Edge address bar, and press Enter:

    edge://settings/searchEngines

    Select Bing, Google, DuckDuckGo, or another search provider you trust and make it the default. This address opens the list of search engines; the default is set one page back, on Address bar and search, under Search engine used in the address bar.

    Remove any unknown search engines from the list, especially providers with strange names or addresses that you did not add yourself: click More actions (…) next to the engine and remove it.

    Restart Edge and perform a search from the address bar. If searches are no longer redirected, you can stop here.

    Microsoft Edge Search engines list with the demo engine Search Results Example (1) and its More actions button (2); below, the Address bar and search page with the Search engine used in the address bar menu showing Bing (Default) (3)
  8. If the redirect remains, clean the corrupted search data without deleting the Edge profile

    Use this additional step only if Edge continues to redirect searches after the normal reset.

    This command cleans the search-engine database from every local Edge profile while keeping your favorites, saved passwords, browsing history, cookies, and profiles.

    Before continuing: save anything you are working on because the command will close Microsoft Edge.

    1. Open the Windows Start menu.
    2. Type PowerShell.
    3. Open Windows PowerShell. Administrator access is not required.
    4. Copy the entire command below.
    5. Paste it into PowerShell and press Enter.
    $stamp = Get-Date -Format "yyyyMMdd-HHmmss"
    $root = Join-Path $env:LOCALAPPDATA "Microsoft\Edge\User Data"
    
    Get-Process -Name msedge -ErrorAction SilentlyContinue |
        Stop-Process -Force -ErrorAction SilentlyContinue
    
    Start-Sleep -Seconds 2
    
    if (-not (Test-Path -LiteralPath $root)) {
        Write-Host "The Microsoft Edge profile folder was not found:"
        Write-Host $root
        return
    }
    
    $profiles = Get-ChildItem -LiteralPath $root -Directory |
        Where-Object {
            $_.Name -eq "Default" -or
            $_.Name -match "^Profile \d+$"
        }
    
    $movedFiles = 0
    
    foreach ($profile in $profiles) {
        foreach ($name in @(
            "Web Data",
            "Web Data-journal",
            "Web Data-wal",
            "Web Data-shm"
        )) {
            $file = Join-Path $profile.FullName $name
    
            if (Test-Path -LiteralPath $file) {
                $backup = "$file.search-reset-backup-$stamp"
    
                try {
                    Move-Item -LiteralPath $file -Destination $backup -ErrorAction Stop
                    Write-Host "Cleaned: $($profile.Name)\$name"
                    $movedFiles++
                }
                catch {
                    Write-Warning "Could not clean: $file"
                }
            }
        }
    }
    
    Write-Host ""
    
    if ($movedFiles -gt 0) {
        Write-Host "Microsoft Edge search data has been cleaned." -ForegroundColor Green
        Write-Host "You can now reopen Microsoft Edge."
    }
    else {
        Write-Host "No Edge search database files were found." -ForegroundColor Yellow
    }

    The command does not permanently delete the original files. It renames them as backup files, and Edge creates a clean search database when it starts again.

    Note: this additional cleanup may also reset saved form-fill suggestions, saved addresses, payment cards saved only on this computer, and manually added search engines. It does not delete favorites, passwords, or browsing history.

  9. Reopen Edge and test the browser

    Open Microsoft Edge again, visit edge://settings/searchEngines, and select your preferred search engine (one page back, on Address bar and search, under Search engine used in the address bar).

    Perform several searches from the address bar to confirm that the redirect is gone.

    Keep synchronization for Settings and Extensions turned off until you are certain that the computer and extensions are clean. If you enable them again, turn them on one at a time and test Edge after each change.

    Microsoft Edge Search engines list with the demo engine Search Results Example (1) and its More actions button (2); below, the Address bar and search page with the Search engine used in the address bar menu showing Bing (Default) (3)
  10. If Edge still redirects your searches

    Open edge://policy. If this is your personal computer and Edge displays unknown policies such as ExtensionInstallForcelist or DefaultSearchProvider, the hijacker may be installed outside the browser profile.

    In that situation, continue with the next malware-removal steps and run a complete antivirus scan. If the computer belongs to a company or school, contact its IT administrator before changing any policies.

    Microsoft Edge Policies page, Microsoft Edge Policies table with the message No policies set highlighted (1)

STEP 3: Use Rkill to terminate suspicious programs

Next, we’ll download and run Rkill to stop any suspicious processes running in the background. This prevents the malware from interfering with the removal tools in the following steps.

RKill is a program that was developed at BleepingComputer.com that attempts to terminate known malware processes so that your normal security software can then run and clean your computer of infections. When RKill runs it will kill malware processes and then removes incorrect executable associations and fixes policies that stop us from using certain tools.

  1. Download Rkill.

    You can download RKill to your computer from the below link. When at the download page, click on the Download Now button labeled iExplore.exe. We are downloading a renamed version of Rkill (iExplore.exe) because some malware will not allow processes to run unless they have a certain filename.

    RKillStops malware processes so other tools can run
    Download RKillOpens the BleepingComputer download page in a new tab.
  2. Run RKill.

    After downloading, double-click the iExplore.exe icon to kill malicious processes. In most cases, downloaded files are saved to the Downloads folder.
    The program may take some time to search for and end various malware programs.

    RKILL Window

    When it is finished, the black window will close automatically and a log file will open. Do not restart your computer. Proceed to the next step in this guide.

STEP 4: Use Malwarebytes to remove Trojans and unwanted programs

Now we’ll install Malwarebytes and run a full scan to detect and remove infections, adware, and potentially unwanted programs from your computer.

Malwarebytes is one of the most popular and trusted anti-malware tools for Windows — and it’s completely free for removing infections. It catches threats that many antivirus programs miss, including adware, browser hijackers, and trojans. Follow the steps below to scan your PC and remove what Malwarebytes finds.

  1. Download Malwarebytes

    Click the button below to download the latest version of Malwarebytes for Windows from the official source. The free version is all you need — it will scan your computer and remove adware, browser hijackers, and other malicious software at no cost.

  4. Optional: Check for rootkits with a Custom Scan

    You don’t need to change any settings for a normal scan. The standard Threat Scan in the next step is enough for most problems, so you can go straight to it.

    If you also want to check for rootkits, use a Custom Scan. In current versions of Malwarebytes, rootkit scanning is only available there:

    1. On the Scanner tile, click the three-dot menu and select Advanced Scan.
    2. Choose Custom Scan. In its options, check Scan for rootkits.
    3. Select your system drive (usually C:\) as the location to scan, then start the scan. It takes longer than a Threat Scan.
    4. When it finishes, review and quarantine the results as described in the steps below.

    Rootkit scanning isn’t available on Windows devices with ARM processors.

  5. Start the Scan

    Click the blue Scan button. Malwarebytes will automatically update its virus database and start checking your computer for malware.

  6. Wait for the Scan to Finish

    The scan checks your entire system for browser hijackers and other malicious programs, so it can take 5 to 20 minutes depending on your computer. Feel free to do something else — just check back occasionally to see the progress.

  7. Quarantine the Detected Threats

    When the scan is done, you’ll see a list of everything Malwarebytes found — malware, adware, and potentially unwanted programs. Click the “Quarantine” button to remove all of them at once.

    Malwarebytes will now remove the malicious files and registry entries and move them safely into quarantine.

  8. Restart Your Computer

    Some threats can only be fully removed after a reboot. If Malwarebytes asks you to restart, click Yes. Once you’re logged back in, Malwarebytes has finished removing the threats it found.

STEP 5: Use HitmanPro to remove rootkits and other malware

Next, we’ll run a second-opinion scan with HitmanPro to catch Trojans, rootkits, and other malicious programs that may have survived the previous step.

HitmanPro is a second-opinion scanner — it’s designed to catch what your main antivirus might have missed. Instead of relying on a single detection engine, it checks the behavior of files in the locations where malware usually hides. Anything suspicious is checked online, where it’s analyzed by several antivirus engines in HitmanPro’s Scan Cloud.

Good news: scanning is completely free, with no limits. You only need a license when it’s time to remove what was found — and even then, you can activate a free one-time 30-day trial to remove what it finds at no cost. The trial works once per computer. After that, removal needs a paid license, and the purchase screen shows the current price.

  1. Download HitmanPro

    Click the button below to download HitmanPro. Remember — the scan is free, so you have nothing to lose by checking your PC.

    Download HitmanProFree scan. Removing threats needs the free 30-day trial. Opens the official HitmanPro page in a new tab.
  2. Install HitmanPro

    When the download finishes, open your Downloads folder and double-click the file “hitmanpro_x64.exe”. (On 32-bit Windows 10, the file is named “hitmanpro.exe”.)

    Double-click on the HitmanPro file

    If a User Account Control pop-up asks whether HitmanPro can make changes to your device, click “Yes” to continue.

  3. Follow the On-Screen Prompts

    On the HitmanPro start screen, click “Next” to begin the system scan. No lengthy setup required — it goes straight to work.

  6. Click “Activate Free License”

    To remove the malicious files, click the “Activate free license” button. This starts your free 30-day trial — no payment details needed — and unlocks the full cleanup.
    Click on the Activate free license button

    When the removal is complete, HitmanPro will show a summary of everything it cleaned. Click Next, then click Reboot if prompted. If there’s no reboot prompt, click Close. Then check whether the problems you noticed have stopped. If they come back, save the HitmanPro log and ask for help in our forum.

STEP 6: Use AdwCleaner to remove malicious browser policies and adware

We’ll now use AdwCleaner to remove malicious browser policies and unwanted browser extensions — the leftovers that keep hijacking your browser settings even after the malware itself is gone.

AdwCleaner is a free on-demand scanner that specializes in adware, browser hijackers, and unwanted toolbars — the exact threats that mainstream antivirus programs often miss. It also includes tools that repair the damage malware leaves behind, like hijacked browser settings and malicious policies. It’s a quick scan that’s well worth running.

  1. Download AdwCleaner

    Click the button below to download AdwCleaner — it’s free, portable, and requires no installation.

    Download AdwCleanerOpens the official download page in a new tab.
  2. Run AdwCleaner

    Open your Downloads folder and double-click the file named “adwcleaner.exe“. There’s no installation — the program starts right away.
    Download AdwCleaner on your computer

    If Windows asks whether you want to allow AdwCleaner to run, click “Yes“. When the license agreement appears, click I agree to continue.

    Windows ask if you want to run AdwCleaner

  3. Leave “Reset Chrome policies” off unless you need it

    AdwCleaner can reset Chrome policies, the settings that malware sometimes uses to lock your browser so you can’t change it back. This option removes every Chrome policy, including legitimate ones set by an employer, a school, or parental-control software, so leave it off for a normal scan.

    AdwCleaner applies this option only if you run Basic Repair at the end of the cleanup. Malwarebytes advises running Basic Repair only when a support agent asks you to, and it also runs every other repair action that is turned on in the same list. If this is your own personal PC and chrome://policy in Chrome lists policies you didn’t set, ask for help in our forum instead. On a work or school computer, ask the IT administrator.

  4. Start the Scan

    Click “Dashboard” on the left side of the window, then click the “Scan Now” button.

    Click on Scan to start a AdwCleaner scan

  5. Wait for the Scan to Finish

    AdwCleaner will now check your computer for adware and other malware. This usually takes only a few minutes — it’s one of the fastest scanners around.

  6. Quarantine the Detected Threats

    When the scan finishes, AdwCleaner lists everything it found. Review the list and uncheck any program you installed on purpose and want to keep, then click Next. If AdwCleaner also found preinstalled software, it shows that list next. Review it the same way, then click “Quarantine“. Older versions show the Quarantine button on the first list, as in the image below.

    Click on Quarantine to remove malware

  7. Click “Continue” to Finish the Cleanup

    Save any open work first — AdwCleaner needs to close your open programs before it can clean. When you’re ready, click the “Continue” button.
    Click Continue to remove malicious files

    AdwCleaner will now move the selected items to quarantine. If it asks you to restart your PC, allow it. When you’re back in Windows, AdwCleaner may offer a Basic Repair. Click Skip Basic Repair. Malwarebytes recommends running Basic Repair only when a support agent asks you to. Then check whether the problems you noticed have stopped.

STEP 7: Perform a final check with ESET Online Scanner

Finally, we’ll run ESET Online Scanner as a last check for anything the earlier scans missed. A clean result is a good sign, but no scanner can guarantee that a computer is malware-free.

ESET Online Scanner is a free second-opinion scanner that performs a deep, full-system check for viruses, trojans, rootkits, and other malware. We use it as the final step because it’s thorough and can catch threats the earlier scans missed. A clean result is a good sign, but no scanner can guarantee that a computer is malware-free.

  1. Download ESET Online Scanner

    Click the button below to download ESET Online Scanner.

  2. Run the Installer

    When the download finishes, open your Downloads folder and double-click “esetonlinescanner.exe“.

  3. Install ESET Online Scanner

    On the start screen, select your language from the drop-down menu and click Get started.

    Choose your preferences for the Customer Experience Improvement Program and the Detection feedback system (either choice is fine), then click Continue.

  4. Start a Full Scan

    Click Full Scan — this checks your entire computer, not just the common hiding spots.

    Start a Full Scan with ESET Online Scanner

    Select Enable for Detection of Potentially Unwanted Applications — this lets ESET catch adware and bundled junk programs, not just viruses. Then click Start scan.

    Image - Enable PUA Detection and Start Scan

  5. Wait for the Scan to Finish

    ESET will now check every file on your computer. Because it’s a full scan, this can take a while — often an hour or more, depending on how much data you have. Leave it running in the background and check on it from time to time.

    Image- Wait for the ESET Online Scanner scan to finish

  6. Review the Results

    When the scan completes, the Found and resolved detections screen appears. Detected threats are usually cleaned and quarantined automatically. Click View detailed results to see exactly what was removed, and ask for help in our forum if any item could not be cleaned.

    If ESET found nothing, restart your computer and check whether the problems you noticed have stopped. If they continue, ask for help in our forum.

When you’ve finished these steps, check whether the problems you noticed have stopped. If they continue, see the options below.

If you are still having problems with your computer after completing these instructions, then please follow one of the steps:

Check Accounts and Company Access After the Infection

  • Review email and cloud-account sign-in history
  • Revoke unfamiliar sessions, app passwords and access tokens
  • Check browser-saved passwords and replace exposed credentials
  • Inspect sent mail and collaboration tools for attacker messages
  • Ask IT to review endpoint, VPN and network logs
  • Notify financial partners if payment information was accessible

Frequently Asked Questions

Is ScreenConnect itself malware?

No. ScreenConnect is legitimate remote-support software. Criminals can configure or repackage legitimate tools for unauthorized access, which is what makes this installer dangerous.

Can reading the email infect the computer?

No. The infection chain requires the recipient to follow the link, download the archive and run the program inside. Reading or deleting the message does not activate the RAT.

Why does the email use a PDF preview if the download is a ZIP?

The PDF preview creates trust. The fake outdated-reader warning then gives the attacker a reason to replace the expected document with executable content inside an archive.

The Bottom Line

The Finance Department Secure Document email is a malware-delivery trap. Its confidential PDF, named recipient and professional portal language all lead to a trojanized remote-access installer.

Do not use the Open Document button. If the installer was executed, disconnect the computer, contact the security team, scan the entire system and change exposed passwords from a clean device.
