Beware the Windows Key + R Fake Pop-Ups – ClickFix Malware EXPOSED

If a pop-up or verification page tells you to press Windows key + R, paste something with Ctrl + V, and then press Enter, stop. This is not a normal CAPTCHA or browser check. It is a social-engineering technique used to make people run malware on their own computers.

The Windows key + R shortcut is safe by itself. It only opens the legitimate Windows Run dialog. The danger begins when an unfamiliar website places a command on your clipboard and persuades you to paste and execute it.

Overview

Windows key + R fake pop-ups are malware-delivery pages that disguise operating-system commands as a security check, CAPTCHA, browser repair, video fix, or human-verification step. Security researchers commonly call this technique ClickFix.

The page may copy Cloudflare, Google reCAPTCHA, Microsoft, a browser warning, or a familiar website. Its design changes, but the core instruction is usually the same: open Windows Run, paste clipboard content, and press Enter.

This sequence matters because it moves the attack out of the browser and into Windows. Instead of exploiting a software vulnerability, the criminals convince the visitor to launch their command through a trusted Windows feature.

If you are here because you already followed part of the instructions, use this quick answer:

• You only pressed Windows key + R: You opened the Run dialog. Nothing was installed merely by opening it. Press Escape and close the suspicious page.
• You pasted with Ctrl + V but did not press Enter: Close Run without executing the text. Replace the clipboard by copying a harmless word. The pasted command should not have run.
• You pasted and pressed Enter: Treat the computer as potentially compromised. Disconnect it from the internet and follow the recovery steps in this guide.
• You only viewed the pop-up: Close the tab. Seeing the page alone does not mean its command executed.

Is pressing Windows key + R safe?

Yes. Windows key + R is a standard Windows shortcut. It opens the Run dialog, a small tool that lets users launch applications, folders, settings, scripts, and administrative utilities by typing their names or paths.

Using Run for a command you understand can be perfectly legitimate. For example, an IT technician may ask an employee to open a known Windows management tool during a support session.

What is not legitimate is an unsolicited website asking you to paste text you have not inspected into Run. A real CAPTCHA does not need access to a Windows command launcher. A website can verify a browser interaction without asking the visitor to execute system commands.

The shortcut is therefore not the threat. The attacker’s clipboard command and the instruction to press Enter are the threat. Think of Run as a doorway: opening the door is harmless, but allowing an unknown person to choose what passes through it is not.

What does the fake pop-up usually say?

Wording varies between campaigns. The pop-up may say that verification failed, a browser error must be repaired, a video codec is missing, a DNS problem needs fixing, or a security check must be completed.

A common version displays instructions similar to these:

Other variants add a fake verification ID, progress spinner, Ray ID, error code, or countdown. These details are visual props. They do not make the instructions safer or prove that the page belongs to the company whose logo is displayed.

The screenshot above shows a fake Cloudflare version. We examine that specific imitation in our Fake Cloudflare Human Verification scam report. The same Windows Run trick also appears without Cloudflare branding, which is why recognizing the keyboard sequence is more useful than memorizing one page design.

Why do scammers use Windows Run?

Most people have learned to be suspicious of unknown program downloads. A pop-up that says “download and open this file” may therefore be ignored or blocked by the browser.

ClickFix changes the presentation. The website claims that the visitor is performing a manual verification or fixing an innocent problem. The victim still launches malicious code, but the action feels like a technical step rather than a download.

The operation also abuses tools already included with Windows. A pasted command can start PowerShell, Command Prompt, Windows Script Host, mshta.exe, rundll32.exe, or another legitimate component. Those tools are not malicious, but attackers can misuse their capabilities to retrieve and run harmful content.

Microsoft Threat Intelligence describes ClickFix as a widespread social-engineering technique that has delivered information stealers, remote-access trojans, loaders, rootkits, and other malware. The lure is successful precisely because it asks the user to complete the execution chain.

How can a website put a command on the clipboard?

Modern browsers provide clipboard features for legitimate purposes, such as a “Copy” button beside a coupon code or account number. Access is restricted by browser rules and often requires a click or another user interaction.

A malicious page can disguise that interaction as a CAPTCHA checkbox, verification button, repair button, or “I’m not a robot” prompt. When the visitor clicks, the page can attempt to copy attacker-prepared text while showing instructions for the next steps.

The visitor may never see the full clipboard content. The command could be longer than the Run box, encoded, or constructed so that only an innocent-looking phrase appears at the visible end.

This is why pasting the line and trying to judge it visually is not a safe test. Do not paste it into Run, PowerShell, Command Prompt, Terminal, an address bar, or any other place that might interpret part of it.

Can a command run just because it was copied?

Normally, copying text does not execute it. Opening Windows Run does not execute it either. The decisive step is pressing Enter, clicking OK, or otherwise launching the pasted content.

There can be exceptions if another malicious file, browser extension, or program is already active on the computer, but the standard ClickFix sequence relies on the victim completing all three steps. This distinction is important because it prevents unnecessary panic when someone stopped before execution.

If you pasted the text but did not press Enter, close the dialog with Escape. Then copy a harmless word so the unknown command is no longer on the clipboard. Do not return to the page to investigate it.

What can the pasted command do?

A Run command can launch a local program, contact a remote server, download a script, decode hidden instructions, create a scheduled task, or start another process. It may do several of these things in a fraction of a second.

The first command is often only a small loader. It connects to an attacker-controlled address and retrieves the next stage. That stage can perform system checks, avoid security tools, establish persistence, and install the final malware.

Different visitors can receive different commands. Operators may rotate their infrastructure throughout the day or show a harmless destination to security scanners. A page that appeared inactive during a later visit may still have delivered a working command earlier.

The absence of a visible download is not reassuring. PowerShell and other system tools can retrieve content in the background. A black window may flash briefly and disappear, or no obvious window may appear at all.

What malware is associated with Windows R scams?

The Windows key + R scam is a delivery method, not one specific virus. The final payload depends on the campaign, the victim’s location, the device, and what the operators are distributing at that moment.

Observed ClickFix campaigns have delivered several categories of malware:

• Information stealers that collect browser passwords, authentication cookies, autofill records, cryptocurrency data, and files.
• Remote-access trojans that give criminals ongoing control of the computer.
• Loaders that download additional malware after the first command succeeds.
• Banking malware designed to capture financial credentials or manipulate sessions.
• Proxy malware that routes someone else’s traffic through the victim’s connection.
• Ransomware precursors that help criminals prepare a later attack.

Microsoft tracks malicious fake CAPTCHA pages with detections including Trojan:HTML/FakeCaptcha. A security alert may use that name for the web lure even when the final downloaded malware has a different detection name.

It is not possible to identify a precise malware family from the pop-up’s appearance alone. Anyone claiming that every Windows R pop-up installs the same trojan is oversimplifying a delivery system that can change payloads rapidly.

What information could be stolen?

Information stealers are a common outcome because browsers and apps contain valuable data that can be collected quickly. A successful infection may expose much more than the account used on the website where the pop-up appeared.

Potential targets include:

• Saved passwords and autofill information in Chrome, Edge, Firefox, and other browsers.
• Session cookies that keep email, social media, shopping, and cloud accounts signed in.
• Credit-card details and addresses stored in a browser profile.
• Password-manager session data if the vault was unlocked.
• Cryptocurrency wallet extensions, wallet files, seed phrases, and copied addresses.
• Discord, Telegram, Steam, VPN, FTP, remote-desktop, and developer credentials.
• Documents, screenshots, desktop files, and basic information about the device.

Stolen cookies are especially important. Changing a password does not always invalidate every active session automatically. Recovery should include signing out other devices and revoking existing sessions, not merely choosing a new password.

Where do Windows key + R fake pop-ups come from?

Many people encounter the lure after clicking a pop-up, advertisement, fake download button, streaming player, or link on a questionable website. Others arrive through malicious search ads, compromised legitimate websites, browser notification spam, or messages containing a booby-trapped link.

The page that displays the instructions may be several redirects away from the site the visitor first opened. This can make it feel as though the warning came from the browser, Windows, or a trusted service.

The address bar remains the best source of identity. Logos and company names inside the page are controlled by whoever built it. A Cloudflare logo on an unrelated domain does not turn the page into a Cloudflare service.

Warning signs that identify the scam

• A website asks you to press Windows key + R as part of a CAPTCHA or human check.
• The instructions continue with Ctrl + V and Enter.
• The page asks you to open PowerShell, Command Prompt, Terminal, or Windows Run.
• A “Fix,” “Verify,” or “I’m not a robot” button silently copies text.
• The browser displays an unrelated or random-looking domain.
• The page says you must run a command to view a video, download a file, or repair the browser.
• A fake error claims that DNS, fonts, certificates, or browser components need an immediate command-line fix.
• The page asks you to disable antivirus protection before continuing.

Any website instruction that requires pasting an unknown command into Windows should be treated as hostile. Legitimate services can verify a user inside the browser.

Real CAPTCHAs do not execute Windows commands

A genuine CAPTCHA might ask you to select a checkbox, identify objects, solve a simple visual prompt, or wait while the browser is checked. Some modern systems complete verification without any visible challenge.

For example, Cloudflare’s official Turnstile documentation describes managed, non-interactive, and invisible browser-based widgets. None require Windows Run, PowerShell, a downloaded verification tool, or a pasted command.

A real support technician might use Run while actively troubleshooting a known issue with you. That is a different context from an unexpected webpage claiming the shortcut proves you are human. Do not grant remote access or run commands for an unsolicited caller who appeared after the same pop-up.

How The Operation Works

The criminals build the campaign as a chain of replaceable parts. The advertisement, redirect service, fake verification page, command server, and final malware may all use different domains.

1. The visitor clicks an advertisement or compromised link

The initial click can come from a fake play button, download link, advertisement, search result, browser notification, email, or social-media message. A compromised legitimate website can also inject the first redirect without its owner’s knowledge.

Some campaigns open a new tab, while others replace the current page. Full-screen mode, dimmed backgrounds, and familiar security branding make the change feel like part of the original website.

2. A redirect system evaluates the visitor

The traffic system may examine the visitor’s country, browser, operating system, IP reputation, referral source, and previous visits. Windows users can receive the Win+R instructions while mobile users see ordinary advertising.

Known scanners or datacenter connections may be sent to a harmless page. This filtering helps the criminals keep their domains active and makes reports difficult to reproduce.

3. The landing page creates urgency and trust

The fake page imitates a recognizable service or presents a technical error. It may say that verification is required before the website loads, that unusual traffic was detected, or that a browser problem prevents access.

A progress animation and numbered steps reduce hesitation. The instructions are short enough to follow without thinking about what each keyboard action really does.

4. A click prepares the clipboard content

The page encourages the victim to click a verification control. That interaction can allow its script to copy a command to the clipboard. The page then claims the text is a verification code or repair instruction.

The copied line may use encoding, unusual spacing, shortened addresses, environment variables, or harmless-looking comments. Its purpose is to hide the meaningful behavior from a person who sees only a small part of it.

5. Windows key + R opens a trusted launcher

The first keyboard step opens Windows Run. No browser exploit is required. The victim voluntarily moves the attack into a legitimate operating-system interface.

At this stage, no malware should have launched merely because Run is open. The operation still needs the victim to paste and execute the prepared line.

6. Ctrl + V transfers the command

The second step places the clipboard text in Run. A long line may extend beyond the visible input box, preventing the visitor from reading it completely.

Some campaigns put a visible verification phrase at the end of the command. The phrase is a decoy. Earlier parts of the same line can still download or execute code.

7. Enter launches the first stage

Pressing Enter instructs Windows to process the pasted line. A built-in utility may open briefly, run in a hidden mode, or start a script without displaying a conventional installer.

The first stage often contacts a separate server. It can download another file, decode embedded content, or execute a second command held in memory.

8. The malware establishes access or steals data

A loader may create a scheduled task or startup entry so it returns after a restart. An information stealer can collect browser data within minutes, while a remote-access trojan can keep the machine connected to its operator.

The computer may continue to look normal. Quiet operation is valuable to criminals because it gives them time to sell credentials, reuse sessions, and add other malware.

9. The victim is redirected to reduce suspicion

After the command runs, the page may display a checkmark, load the expected video, show a harmless website, or claim that verification succeeded. This gives the victim a plausible explanation for the brief activity.

The original landing domain may disappear soon afterward. Operators can replace it while keeping the same advertisements and malware infrastructure.

If You Pressed Windows Key + R

Stay calm and match your response to the last action you completed. Opening Run and executing a command are not the same event.

If you only opened the Run dialog

Press Escape or click Cancel. Close the suspicious browser tab. Opening Run by itself does not install the malware described in this scam.

If the pop-up keeps returning, check the browser’s notification permissions and remove permission for unfamiliar sites. Also inspect extensions and recently installed applications, because adware or a malicious extension can cause repeated redirects.

If you pasted the text but did not press Enter

Do not click OK. Press Escape to close Run without launching the line. Copy a harmless word afterward to overwrite the clipboard content.

No command should have executed through Run if you stopped before Enter or OK. A normal security scan is still sensible if you reached the page through repeated redirects or opened any downloaded file.

If you pressed Enter or clicked OK

Assume the unknown command may have run successfully, even if nothing visible happened. Take the following steps in order.

1. Disconnect the computer from the internet. Turn off Wi-Fi and unplug Ethernet. This can interrupt additional downloads, remote control, and ongoing data theft.
2. Stop using the computer for sensitive tasks. Do not sign in to email, banking, payment apps, shopping accounts, work portals, cloud services, password managers, or cryptocurrency wallets.
3. Use a different clean device for urgent account activity. A phone or computer that did not run the command is safer for changing passwords and contacting providers.
4. Record the incident. Write down the domain, approximate time, browser, instructions followed, and anything that flashed on the screen. Photograph existing alerts, but do not revisit the page.
5. Tell your workplace or school IT team immediately. If the device or any account belongs to an organization, let its security team coordinate the response. The command may expose shared systems and credentials.
6. Run Microsoft Defender Offline. Open Windows Security, select Virus & threat protection, choose Scan options, and run Microsoft Defender Antivirus (offline scan). The computer restarts and checks for threats before normal Windows is fully loaded. Microsoft explains the option in its official Windows Security guidance.
7. Complete the full malware-removal process below. ClickFix attacks can use several stages. Removing one detected script or file does not prove that every downloaded component is gone.

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 clean it completely.

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

• STEP 1: Uninstall malicious programs from Windows
• STEP 2: Reset browsers back to default settings
• STEP 3: Use Rkill to terminate suspicious programs
• STEP 4: Use Malwarebytes to remove Trojans and unwanted programs
• STEP 5: Use HitmanPro to remove rootkits and other malware
• STEP 6: Use AdwCleaner to remove malicious browser policies and adware
• STEP 7: Perform a final check with ESET Online Scanner

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.

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 this method will remove all extensions, toolbars, and other customizations but will leave your bookmarks and favorites 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.

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.

   

   RKILL DOWNLOAD LINK
   (The above link will open a new page from where you can download Rkill)

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.

   

   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 and clean your PC in just a few minutes.

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.

   

   DOWNLOAD MALWAREBYTES FOR WINDOWS (FREE)
   
   (The link opens in a new page where your download will start)

2. Install Malwarebytes

   When the download finishes, open your Downloads folder and double-click the MBSetup file. If Windows shows a User Account Control pop-up, click “Yes” to allow the installation.

   

3. Follow the On-Screen Prompts to Install Malwarebytes

   The setup wizard will walk you through a few quick screens:

   • Choose where you’re installing the program — “Personal Computer” or “Work Computer” — then click Next.

     

   • Malwarebytes will now install on your device. This usually takes under a minute.

     

   • When installation is complete, the “Welcome to Malwarebytes” screen will open automatically.

     

   • On the final screen, click Open Malwarebytes to launch the program.

     

4. Enable “Scan for Rootkits”

   Before scanning, turn on rootkit detection so Malwarebytes can find even the most hidden threats. Click the Settings gear icon on the left side of the screen.

   

   In the settings menu, find “Scan for rootkits” and click the toggle so it turns blue.

   

   Done? Click “Dashboard” in the left pane to return to the main screen.

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 several minutes. 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, your PC is clean and you can continue with the next steps in this guide.

   

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 gets sent to the cloud, where it’s analyzed by two of the best antivirus engines available: Bitdefender and Kaspersky.

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 clean your PC at no cost. (A full license is $24.95 per year for 1 PC.)

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 HITMANPRO (FREE SCAN)
   (The link opens in a new page where your download will start)

2. Install HitmanPro

   When the download finishes, open your Downloads folder and double-click the file: “hitmanpro.exe” on 32-bit Windows, or “hitmanpro_x64.exe” on 64-bit Windows.

   

   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.

   

   

4. Wait for the Scan to Finish

   HitmanPro will now check your computer for malicious programs. This usually takes just a few minutes thanks to its cloud-based scanning.
   

5. Review the Results and Click “Next”

   When the scan is done, HitmanPro will show you everything it found. Click “Next” to remove the detected threats.

   

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.
   

   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, just click Close — your PC is clean.

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 ADWCLEANER (FREE)
   (The link opens in a new page where your download will start)

2. Run AdwCleaner

   Open your Downloads folder and double-click the file named “adwcleaner_x.x.x.exe“. There’s no installation — the program starts right away.
   

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

   

3. Enable “Reset Chrome policies”

   This setting removes malicious browser policies — a trick malware uses to lock your browser settings so you can’t change them back. Click “Settings” on the left side of the window, then turn on “Reset Chrome policies“.

   

4. Start the Scan

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

   

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 will list everything it found. Click the “Quarantine” button to remove all the malicious items at once.

   

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.
   

   AdwCleaner will now delete all detected malware from your computer. If it asks you to restart your PC, allow it — your computer will be clean when you log back in.

STEP 7: Perform a final check with ESET Online Scanner

Finally, we’ll run ESET Online Scanner as a last sweep to confirm nothing was missed. If this scan comes back clean, your 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 — if anything slipped past the previous scans, ESET will find it. A clean result here means your computer is malware-free.

1. Download ESET Online Scanner

   Click the button below to download ESET Online Scanner.

   

   DOWNLOAD ESET ONLINE SCANNER (FREE)
   (The link opens in a new page where your download will start)

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.

   

   On the Terms of use screen, click Accept.
   

   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.

   

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

   

6. Review the Results

   When the scan completes, the Found and resolved detections screen appears. Any threats found were automatically cleaned and quarantined — there’s nothing extra you need to do. Click View detailed results if you want to see exactly what was removed.
   

   If ESET found nothing — congratulations, your computer has passed the final check and is malware-free.

That’s it — your Windows computer is now clean. The Trojans, adware, and any other malware have been removed.

If your current antivirus allowed this malicious program on your computer, you may want to consider purchasing Malwarebytes Premium to protect against these types of threats in the future.
If you are still having problems with your computer after completing these instructions, then please follow one of the steps:

• Run a computer scan with ESET Online Scanner
• Ask for help in our Windows Malware Removal Help & Support forum.

8. Secure your primary email from the clean device. Change its password, review recovery addresses and phone numbers, remove unknown forwarding rules, sign out other sessions, and enable multi-factor authentication.
9. Protect other important accounts. Change unique passwords for banking, payment, work, cloud, shopping, social media, gaming, and communication services. Prioritize accounts that were open or saved in the affected browser.
10. Revoke active sessions and remembered devices. Password changes may not invalidate stolen cookies. Use each service’s security page to sign out other sessions and remove devices you do not recognize.
11. Review the password manager. If the vault was unlocked, change its master password from a clean device, revoke trusted sessions, rotate important stored credentials, and generate new recovery codes.
12. Check financial activity. Review bank, card, payment-app, and retail accounts for unfamiliar transactions or changed contact information. Contact the provider promptly if anything is wrong.
13. Move cryptocurrency when wallet secrets may be exposed. Create a new wallet on a clean device or hardware wallet and transfer assets. A seed phrase or private key is permanently unsafe once stolen.
14. Rotate work and developer secrets. Replace VPN credentials, SSH keys, API tokens, cloud keys, repository access, remote-desktop passwords, and secrets stored in local text files. Review available access logs.
15. Remove the source of repeated pop-ups. Revoke suspicious browser notifications, remove unknown extensions, uninstall unwanted recent software, and reset altered browser settings.
16. Consider reinstalling Windows. A clean installation is the safest option when the computer contained high-value business, administrator, financial, password-manager, or cryptocurrency access, or when you cannot confidently establish what ran.
17. Monitor for delayed abuse. Watch security alerts, login history, password-reset messages, forwarding rules, financial transactions, cloud activity, and wallet transfers for several weeks.

Do not rely on browser cleanup alone

Clearing cookies, cache, downloads, or browsing history does not remove a program launched through Windows Run. Once Enter was pressed, the activity occurred at the operating-system level.

Deleting the command from Run history does not reverse it either. The correct response combines malware scanning with account security because the command may already have stolen session data.

Do not paste the clipboard elsewhere to inspect it

A trained analyst can collect a command inside an isolated environment. On a normal personal computer, experimentation creates unnecessary risk. You could accidentally execute the line in another command-capable application.

Do not post the active command in public comments or send it to friends. If you report it to a security provider, submit it as text only through the provider’s designated channel and explain where it came from.

Should you reset the computer?

A full Windows reinstall offers more assurance than repeated scans when sensitive access was present. This is particularly important for workstations, administrator computers, developer systems, cryptocurrency devices, and machines used for financial accounts.

Back up personal documents carefully, but do not copy unknown scripts, installers, archives, shortcuts, or executable files into the clean system. Reinstall software from official sources and change passwords from a known-clean device.

The Bottom Line

Windows key + R is a legitimate and safe Windows shortcut. A website asking you to combine it with Ctrl + V and Enter is not a legitimate verification. It is trying to make you execute whatever command the site prepared.

If you stopped after opening Run, close it and leave the page. If you pasted but did not execute, cancel and clear the clipboard. If you pressed Enter, disconnect the computer, run the complete malware-removal process, and secure important accounts from a clean device.

The simplest rule is also the strongest: no genuine CAPTCHA, browser check, or human-verification service needs you to paste an unknown command into Windows.
