WinErrorFixer is a fake antivirus software that initiates scam messages on your computer
WinErrorFixer is a corrupt anti-spyware application that shows fake scan results, gives fake reports about system status, and shows annoying warning messages to make users purchase rogue software.
As evident, the main goal of the program is to mislead users and make them think that their PCs are in a bad state, regardless of their actual condition.
If you decide to purchase this app, you might disclose sensitive payment information to cybercriminals. This data can later be misused for fraud, money theft, or even identity fraud. So never purchase this program!
Rogue anti-spyware programs were extremely popular around ten years ago when regulations and security measures were lacking from the operating system, as well as the search engines/browsers and other tools. This opened a gap for cybercriminals to offer users fake security tools which were malicious themselves.
While such programs can be encountered much more rarely, it does not mean that they are gone. In fact, you might still download WinErrorFixer on some shady website or encounter a scam message that promotes it.
Several intrusive pop-ups can show up when Windows is operational. This is done deliberately in order to make it look like the system is infected with various computer parasites that need to be removed immediately. Here is one of the warning messages that is shown directly from the taskbar:
Please do not believe these claims, as the only virus is this program itself. In order to remove it from Windows, you should access Control Panel and try uninstalling it from there. If that does not work, perform a full system scan with or . You should also clean your web browsers - you can do it with .

How WinErrorFixer got on your PC
From our report of Apr 2021 · not reviewed since

Malicious programs might also be delivered automatically via software vulnerabilities or drive-by downloads. Therefore, equip your computer with robust anti-malware software and install the latest security updates for Windows and all the installed apps.

How to remove WinErrorFixer
Nothing it reports is real.
These steps remove it and undo a payment if you made one.
Step 1: Do not pay, and undo a payment if you made one
WinErrorFixer reports problems to sell a licence: the "threats" or "errors" it lists are invented or harmless leftovers. If you already paid, ask your card issuer to dispute the charge and cancel the subscription both in the seller's account and through your bank.
If you called a phone number it showed and let someone connect, treat the PC as remotely accessed and remove the remote tool. Uninstalling it from Windows 11 or Windows 10 does not cancel a subscription by itself.

Step 2: Uninstall WinErrorFixer
Open Settings > Apps > Installed apps in Windows 11, or Settings > Apps > Apps & features in Windows 10. Sort the list by install date and find WinErrorFixer, then choose Uninstall from the three-dot menu next to it (in Windows 10, click the entry and then Uninstall).
Remove anything else installed on the same day that you do not recognise, because such programs usually arrive together in one installer. If the uninstaller opens a browser page with an offer or a survey, close it: the program is removed either way.

Step 3: Remove it from startup
Whatever WinErrorFixer installed usually starts with Windows. Open Task Manager with Ctrl + Shift + Esc, go to Startup apps in Windows 11 or the Startup tab in Windows 10, and disable what you do not know, starting with entries that have an empty Publisher column.
Open file location on the right-click menu shows the file, which helps you decide and tells you what to delete later. Disabling is safe: if something you need stops working, switch it back on.

Step 4: Delete the folders left behind
What the uninstaller leaves behind is usually in the user folders. Open File Explorer, switch on View > Show > Hidden items (in Windows 10 View > Hidden items), and go through
%LocalAppData%,%AppData%, %ProgramData% and the two Program Files folders.Sort by Date modified and delete folders that appeared together with the problem and belong to no program you use. Folders with random names that hold
.exe,.dll, .js or .ps1 files are the strongest sign.Full procedure with screenshots: Remove what malware leaves behind in Windows
Step 5: Scan the PC, then run the offline scan
Open Windows Security > Virus & threat protection > Scan options, run a Full scan and remove everything it finds. Then select Microsoft Defender Antivirus (offline scan) and click Scan now: the PC restarts and scans before Windows loads, which finds files that hide while Windows runs.
Save your work first, because the offline scan takes about 15 minutes. Both scans are built into Windows 11 and Windows 10, and a second scanner from another vendor is a useful extra opinion.

Access your website securely from any location
When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.
If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.
Recover files after data-affecting malware attacks
While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files.
More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.
Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.

Delete WinErrorFixer malware from your PC

Questions about WinErrorFixer
Is WinErrorFixer a virus?
Most programs that appear the way WinErrorFixer did are not viruses in the strict sense. They are potentially unwanted programs:
- real software that arrives bundled with other downloads and then shows offers
- changes browser settings
- starts with Windows
Some are harmless, some are annoying and a few carry adware. What makes it worth removing is that you did not choose it.
Uninstall it from Installed apps and check the startup list and the browsers for anything added the same day. If it refuses to uninstall or returns after a restart, treat it as more serious and run a Microsoft Defender offline scan.
WinErrorFixer will not uninstall. What can I do?
First restart the PC and try again, because the program may have been running and locked its own files. If the uninstaller is missing or fails, start Windows in Safe Mode, where most third-party programs do not start, and remove WinErrorFixer from Installed apps there.
If it still refuses, delete its startup entry and its scheduled task, restart, and try once more. A program that actively prevents removal is behaving like malware, so finish with a Microsoft Defender offline scan. Avoid third-party uninstallers offered on search ads; several of them are unwanted programs themselves.
Will the seller of WinErrorFixer refund me if I ask?
Sometimes, but do not depend on it and do not let them steer the process. If you contact the seller, do it in writing and keep the replies. Never install software, share your screen or give banking details to get a refund.
The more reliable route is your card issuer or PayPal: a chargeback or dispute for a product sold with false claims. If the seller or anyone claiming to represent them calls you first about a refund, treat it as a scam and hang up.
I entered my card number in WinErrorFixer. What should I do?
Call your card issuer using the number on the back of the card, report the purchase as fraud and ask for a new card. Ask them to block further charges from the same merchant. Watch your statements for small test charges, which often come before larger ones.
If you used a password on the order page or the same e-mail for the purchase, change that password and expect phishing e-mails that mention the purchase. Your bank can also tell you whether the merchant is linked to other fraud reports.
Why does WinErrorFixer look so official?
Because copying the design costs nothing and makes people trust it. The program behind winErrorFixer in the list of installed apps borrows Windows colours, icons and wording, sometimes even the name of a well-known security brand. None of that gives it access to real security information.
A real alert can be checked in seconds: open Windows Security from the Start menu and look at Protection history. If nothing is listed there, the official-looking window is fake, and the program that draws it is what needs to be removed.
I let a technician connect to my PC because of WinErrorFixer. Is it safe now?
Not until you check. While connected, the caller could install other programs, create a user account or look at saved passwords. Disconnect from the internet, uninstall the remote access program and anything else installed during the call, and run a full scan and the Microsoft Defender offline scan.
From another device, change your e-mail and banking passwords and turn on two-step verification. If the caller opened your online banking, call the bank today. A reset of Windows is the safest option if you cannot tell what was done.
WinErrorFixer has no uninstaller. How do I get rid of it?
Some scareware does not register an uninstaller, or its uninstaller only opens another sales page. In that case, end the program in Task Manager, then go to Task Manager > Startup apps, right-click its entry and choose Open file location to find its folder. Disable the startup entry, restart in Safe Mode and delete the folder.
Check Task Scheduler for tasks with the same name. Finally, run the Microsoft Defender offline scan, which removes remaining files that Microsoft knows about. Restart afterwards and check that nothing named after WinErrorFixer starts again.
Do I need to buy antivirus after removing WinErrorFixer?
No. Windows 11 and Windows 10 include Microsoft Defender in Windows Security, which provides real-time protection, scheduled scans, the offline scan and protection against unwanted apps at no cost. Keep it switched on and updated, and turn on Reputation-based protection under App & browser control.
If you prefer a third-party product, buy it from the vendor's own site after reading independent test results, never from a pop-up or a phone call. The lesson of WinErrorFixer is that security offers which arrive unasked are the ones to avoid.
What is WinErrorFixer?
WinErrorFixer is fake security software, sometimes called a rogue antivirus or scareware. The program, WinErrorFixer, shows invented or exaggerated problems to make you pay for a licence, and some versions send you to phone "support".
It does not protect the PC, and the threats it lists are not a reason to pay. Fake security programs usually arrive through fake virus warnings on websites, extra offers in free installers or ads for faster PCs. Uninstall it and use the free protection built into Windows instead.
Will Fortect remove WinErrorFixer?
Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.
For WinErrorFixer, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.
Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
