Is One Updater Legit? The Truth About this Sneaky PUP
Written by: Stelian
Published on:
One Updater is a potentially unwanted program (PUP) that claims to check your installed software and update it if needed. At first glance, this seems like a useful service. However, One Updater often comes bundled with adware, browser toolbars, and other questionable programs.
If you suddenly notice One Updater on your computer even though you didn’t intentionally download it, you’re not alone. Many people are finding One Updater installed without their permission or knowledge. This comprehensive guide will explain everything you need to know about One Updater – what it is, how it gets on your PC, its questionable activities, and most importantly, how to get rid of it for good.
What is One Updater?
One Updater is a program that runs in the background on Windows PCs as a scheduled task. It checks for available updates for any software downloaded from the OpenSoftwareUpdater website. If updates are found, it can automatically download and install them or alert the user, depending on configured settings.
The company behind One Updater claims it helps users keep their software up-to-date for better security and functionality. However, most reputable software already includes auto-update capabilities without needing third-party programs like One Updater.
Some key facts about One Updater:
Owner company is OpenSoftwareUpdater
Adds background services that run continuously
Very difficult to fully remove due to deep system integration
Often bundled sneakily with other free software installs
Frequently installs additional questionable programs during setup
While the concept of a centralized software update manager could be useful, One Updater exhibits many behaviors of precarious PUPs. The way it installs itself without consent and hides in the background are red flags.
How Does One Updater Get Installed on Your Computer?
One Updater is rarely directly downloaded and installed by users. Most people find themselves with One Updater unintentionally installed after the fact.
Here are some of the common ways One Updater covertly makes its way onto computers:
1. Bundled with Other Free Software Installs
One of the most common methods is bundling. Many free programs, such as media players, download managers, and file sharing programs will option to install One Updater during their setup wizards.
These offers are typically opt-out, meaning One Updater will be installed unless the user specifically unchecks the box. Because many people gloss over installation screens, it’s easy to miss these sneaky bundled installs.
2.Misleading Advertisements and Popups
Another distribution method is through fake update alerts or phony security warnings. These will prompt users to download scareware tools or updates, which then bundle One Updater with their installers.
Some examples include:
Fake “Flash Player is out of date” alerts
Fake antivirus program warnings
Fake “Windows System Update” popups
Warnings that your PC is infected or compromised
These alerts look convincing but are completely fabricated to get users to unintentionally download PUPs and adware.
3. Malware Infections
Some malware threats will actually install One Updater themselves after infecting a computer. This allows them to have persistent access to continue installing other unwanted programs in the background.
If One Updater shows up immediately after a malware infection, it’s likely the malware planted it as part of their process.
4. Software Cracks and Illegal Programs
Finally, pirated software and illegal program downloads often include One Updater as part of their installer packages.
Peer-to-peer sharing networks and torrent trackers for cracked software are common sources that bundle One Updater with downloads.
What are the Risks of Having One Updater Installed?
On the surface, One Updater seems benign. After all, keeping software updated is generally a good thing. However, because of how it installs itself without permission, One Updater is classified as a “potentially unwanted program” (PUP).
PUPs like One Updater may not be directly malicious, but they exhibit questionable behavior and security risks. Here are some of the potential issues caused by One Updater:
1. Difficult to Remove
Once installed, One Updater embeds itself deeply into the Windows system, making complete removal challenging even for experienced users. It adds background services and registry values that continue running even if you uninstall through standard methods.
Without special removal tools, One Updater will likely remain on your PC continuing to consume resources and be a nuisance.
2. Privacy Concerns
To check for software updates, One Updater likely transmits data about your system and installed programs back to its servers. This raises privacy concerns, as the company can gain insights into your personal software usage and PC details.
3. Resource Heavy
The background services and constant update checking use extra memory and CPU cycles. This slows down your PC’s performance, especially if you have limited RAM and processing power.
4. May Install Other PUPs
As highlighted earlier, One Updater will often install additional potentially unwanted programs (PUPs) during its initial setup process. These extras include adware, browser toolbars, and other questionable add-ons.
5. Security Risks
Any program that installs itself without your approval poses inherent security risks. One Updater creates background services and processes that could be exploited by other malware. The auto-update behavior also means it can download files and alterations without your knowledge.
For these reasons, security experts universally recommend removing One Updater and any other PUPs from your system.
What are the Symptoms of One Updater?
One Updater runs silently in the background for the most part. However, there are some common symptoms that indicate One Updater was installed:
New scheduled tasks named “OneUpdate” in the task scheduler
Running services named “One Updater” or “OpenSoftwareUpdater”
Strange programs you don’t remember installing now on your PC
More frequent pop-up advertisements
Browser homepage and defaults changed without your permission
PC slowdowns and performance lag
You may also directly spot the One Updater program listed in your Windows Programs & Features list or see its shortcut icon on your desktop or start menu. However, it’s designed to operate discretely so you’ll likely have to look closely to find direct evidence.
If you are experiencing any unusual PC behavior like more ads, redirects, or slowness, there’s a good chance One Updater was installed recently.
How to Remove One Updater
If you notice One Updater on your computer, you’ll want to remove it right away along with any other bundled programs to regain privacy and performance.
However, fully removing One Updater is tricky due to how deeply embedded it is in Windows. The standard uninstall process will not completely get rid of One Updater.
Here is a step-by-step process to effectively remove One Updater yourself:
STEP 1: Use Rkill to terminate malicious processes
In this first step, we will download and run Rkill to terminate malicious processes that may be running on your computer.
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.
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)
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 2: Uninstall malicious programs from your computer
In this second step, we will manually check if any unknown or malicious programs are installed on the computer. Sometimes adware and browser hijackers can have a usable Uninstall entry that can be used to remove them.
Windows 11Windows 10Windows 8Windows 7
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.
Go to “Apps & Features”
In the Settings window, click “Apps” in the sidebar, then select “Apps & Features“.
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 the three dots next to it and select “Uninstall“.
Didn’t find any suspicious programs? That’s fine — not all infections install visible apps. Just continue with the next step in this guide.
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.
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).
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.

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 3: Remove malicious browser policies from Windows
In this third step, we will download the Chrome Policy Remover file (credits to Stefan Van Damme) and remove the malicious browser policies. .
Download the Chrome Policy Remover
Click the button below to download the Chrome Policy Remover for Windows — a small batch script that automatically removes the malicious policies that malware uses to lock your Chrome settings.
Seeing a security warning? That’s expected — browsers and Windows flag all batch (.bat) files as a precaution, regardless of what they do. The Chrome Policy Remover is a trusted, widely used tool; click “Keep” to proceed with the download.
Run the file as administrator
Right-click the “delete_chrome_policies.bat” file (usually in your Downloads folder) and select Run as administrator. Administrator rights are required because Chrome policies are stored in protected system settings — without them, the tool can’t remove the policies.
Confirm and let the script finish
Windows will ask for confirmation before allowing the script to make changes — click “Yes” (or “Run“, depending on your Windows version). A Command Prompt window will open and the script will remove the policies automatically; this only takes a few seconds. When it’s done, close the window.
With the malicious policies removed, Chrome’s settings are unlocked again. In the next step, we’ll reset the browser to its defaults.
STEP 4: Remove malicious files and folders from Windows
In this fourth step, we will manually search and remove malicious scheduled tasks and folders on your computer.
1. Delete Malicious Scheduled Tasks
This infection often creates a scheduled task in the Windows Task Scheduler that reinstalls the malware every few minutes after you delete it. That’s why the redirects keep coming back even after a cleanup — until this task is removed, the infection will keep restoring itself.
Type “Task Scheduler” in the Windows search bar and open the app, as shown below.
Alternatively, press Windows + R, type “taskschd.msc“, and press Enter.
In the Task Scheduler window, click Task Scheduler Library in the left pane.
Look through the list for the malicious scheduled task. It often imitates a legitimate name (e.g. Chrome_Policy, Chrome_Bookmarks, Chrome_Folder) or has a random string of characters as its name. A useful check: click a task and look at the Actions tab — if it runs a file from the AppData folder, it’s almost certainly malicious. Right-click the task and select “Delete“.
2. Delete Malicious Files from the AppData\Roaming Folder
Next, we’ll delete the malicious files the infection stores in the AppData\Roaming folder.
Press Windows + R to open the Run app (or type “Run” in the Windows search bar).
In the Run box, type “%AppData%” and click OK. Windows will open the Roaming folder directly.
Look for and delete any unknown folders with names like Default, Chrome32, Energy, Bloom, or Travel. The exact names on your computer may differ, but the pattern is the same: short, generic-sounding names that don’t match any program you’ve installed.
Be careful: only delete folders you’re confident don’t belong to a real program. Legitimate apps (Adobe, Spotify, Discord, etc.) also store their data here. If you’re unsure about a folder, search its name online first — or skip it; the automated scanners later in this guide will catch what you miss.
3. Delete Malicious Files from the AppData\Local Folder
Now we’ll do the same in the AppData\Local folder, and also remove the malicious Chrome extension the infection installed.
Press Windows + R to open the Run app (or type “Run” in the Windows search bar).
In the Run box, type “%localappdata%” and click OK. Windows will open the AppData\Local folder directly.
Look for and delete the Default, WindowsApp, and ServiceApp folders, if present. (The same caution applies — when in doubt, look the name up before deleting.)
Next, open the Google folder and navigate to Google > Chrome > User Data > Default (or Profile) > Extensions. Inside the Extensions folder, find and delete the malicious extension’s folder — it will have a long, random-looking name. If you’re not sure which one it is, you can check each folder’s contents, or compare the names against the extensions visible at chrome://extensions in Chrome.
Important: inside User Data, the folder named “Default” is your legitimate Chrome profile — do not delete it. Only delete the individual extension folder inside Extensions.
4. Fix the Hijacked Chrome Shortcut
This malware often modifies your Chrome shortcut so that every time you open the browser, the malicious extension loads with it. Here’s how to clean the shortcut:
Right-click the Google Chrome shortcut on your desktop or Start Menu and select “Properties“.
On the Shortcut tab, check the “Target” field. It should end with chrome.exe” and nothing more. Delete any extra text appended after it — especially anything referencing the AppData folder, such as: –load-extension=C:\Users\%USERNAME%\AppData\Local\Default
Click OK to save the changes.
Open Chrome from the shortcut as usual — the malicious extension should no longer load at startup.
Tip: if you’d rather not edit the Target field, there’s an easier fix — right-click the shortcut, select “Open File Location“, then drag chrome.exe to your taskbar to create a fresh, clean shortcut. Delete the old one.
With the malicious tasks, folders, and shortcut modifications removed, we can continue with the next step of this guide.
STEP 5: Reset your browser settings to their defaults
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.
ChromeFirefoxMicrosoft EdgeInternet Explorer
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.

Click “Finish”
Firefox will close, reset itself to default settings, and reopen with a window listing the information that was restored. Click “Finish” — your Firefox is now clean.
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.

Confirm by clicking “Reset”
In the confirmation dialog, click “Reset“. This restores your homepage, search engine, new tab page, and startup pages to default, disables all extensions, and clears temporary data like cookies — undoing the changes the malware made.
Don’t worry: your favorites, browsing history, and saved passwords are safe and will not be deleted.
Reset Internet Explorer to default settings
We will now reset your Internet Explorer browser settings to their default. You can reset Internet Explorer settings to return them to the state they were in when Internet Explorer was first installed on your computer.
Go to “Internet Options”.
Open Internet Explorer, click on the gear icon in the upper-right part of your browser, then select “Internet Options“.
Select the “Advanced” tab, then click “Reset”
In the “Internet Options” dialog box, select the “Advanced” tab, then click on the “Reset” button.
Click on “Reset”.
In the “Reset Internet Explorer settings” section, select the “Delete personal settings” checkbox, then click on the “Reset” button.
Click on “Close”.
When Internet Explorer has completed its task, click on the “Close” button in the confirmation dialogue box. Close your browser and then you can open Internet Explorer again.
STEP 6: Use Malwarebytes to remove trojans and browser hijackers
In this step, we will install and run a scan with Malwarebytes Free to remove any infections, adware, or potentially unwanted programs that may be present on your computer.
Malwarebytes is one of the most popular and trusted anti-malware tools for Windows — and it’s completely free for removing infections.

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.
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 7: Use HitmanPro to scan your computer for rootkits and other malware
In this next step, we will scan the computer with HitmanPro to ensure that no other malicious programs are installed on your device.
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.

STEP 8: Use AdwCleaner to remove adware and malicious browser policies
In this final step, we will download and install AdwCleaner to remove the malicious browser policies that were set by browser hijackers on your computer and delete malicious browser extensions.
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.
Download AdwCleaner
Click the button below to download AdwCleaner — it’s free, portable, and requires no installation.
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.
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“.
Start the Scan
Click “Dashboard” on the left side of the window, then click the “Scan” button.
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.
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.
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.

10 Rules to Avoid Online Scams
Here are 10 practical safety rules to help you avoid malware, online shopping scams, crypto scams, and other online fraud. Each tip includes a quick “if you already got hit” action.
Stop and verify before you click, log in, download, or pay.
Most scams win by creating urgency. Verify using a trusted method: type the website address yourself, use the official app, or call a known number (not the one in the message).
If you already clicked: close the page, do not enter passwords, and run a malware scan.
Keep your operating system, browser, and apps updated.
Updates patch security holes used by malware and malicious ads. Turn on automatic updates where possible.
If you saw a scary “update now” pop-up: close it and update only through your device settings or the official app store.
Use layered protection: antivirus plus an ad blocker.
Antivirus helps block malware. An ad blocker reduces scam redirects, phishing pages, and malvertising.
If your browser is acting weird: remove unknown extensions, reset the browser, then run a full scan.
Install apps, software, and extensions only from official sources.
Avoid cracked software, “keygens,” and random downloads. During installs, choose Custom/Advanced and decline bundled offers you do not recognize.
If you already installed something suspicious: uninstall it, restart, and scan again.
Treat links and attachments as untrusted by default.
Phishing often impersonates delivery services, banks, and popular brands. If it is unexpected, do not open attachments or log in through the message.
If you entered credentials: change the password immediately and enable 2FA.
Shop safely: research the store, then pay with protection.
Be cautious with brand-new stores, “closing sale” stories, and prices that make no sense. Prefer credit cards or PayPal for dispute options. Avoid wire transfers, gift cards, and crypto payments.
If you already paid: contact your card issuer or PayPal quickly to dispute the transaction.
Crypto rule: never pay a “fee” to withdraw or recover money.
Common patterns include fake profits, then “tax,” “gas,” or “verification” fees. Another is a “recovery agent” who demands upfront crypto.
If you already sent crypto: stop paying, save evidence (wallet addresses, TXIDs, chats), and report the scam to the platform used.
Secure your accounts with unique passwords and 2FA (start with email).
Use a password manager and unique passwords for every account. Enable 2FA using an authenticator app when possible.
If you suspect an account takeover: change passwords, sign out of all devices, and review recent logins and recovery settings.
Back up important files and keep one backup offline.
Backups protect you from ransomware and device failure. Keep at least one backup on an external drive that is not always connected.
If you suspect infection: do not connect backup drives until the system is clean.
If you think you are a victim: stop losses, document evidence, and escalate fast.
Move quickly. Speed matters for disputes, account recovery, and limiting damage.
Stop payments and contact: do not send more money or respond to the scammer.
Call your bank or card issuer: block transactions, replace the card if needed, and start a dispute or chargeback.
Secure your email first: change the email password, enable 2FA, and remove unfamiliar recovery options.
Secure other accounts: change passwords, enable 2FA, and log out of all sessions.
Scan your device: remove suspicious apps or extensions, then run a full malware scan.
Save evidence: screenshots, emails, order pages, tracking pages, wallet addresses, TXIDs, and chat logs.
Report it: to the payment provider, marketplace, social platform, exchange, or wallet service involved.
These rules are intentionally simple. Most online losses happen when decisions are rushed. Slow down, verify independently, and use payment methods and account controls that give you recourse.
