The system can be infected if you activate files which contain viruses. Anti-virus programs including Windows Defender wouldn’t allow opening a file or executing any associated program if they suspect the file/program could trigger a virus attack. In such a case, you would encounter the Operation did not complete successfully because the file contains a virus error. I will show you how to fix it with multiple useful solutions in the post.
Operation Did Not Complete Successfully
ERROR_VIRUS_INFECTED error and Operation did not complete successfully because the file contains a virus message can cause a lot of problems on your PC.
There are many antivirus tools available to you online, but none can completely stop the virus. There will always be malicious tools that go unnoticed and even the most expensive & popular antivirus tools can't detect these malicious tools.
Even if your files are 100% legal, your antivirus tools may keep coming up with false positives.
If you want to distinguish whether a file is genuine or not, the process can be delicate. You need to pay close attention if you try to deal with these files.
Before you confirm the file is a false positive, you need to scan the file with several different antivirus scanners. The error code that sometimes occurs underneath the message shown up in the title is actually triggered by Windows.
In some cases these errors can be caused by a false alarm, but you should be able to fix this problem by using one of the solutions in the post.
Fix 1: Adding an Exception for the Folder
If you are using several other antivirus tools besides Windows Defender, you need to know turning off one security tool causes the other to start acting. Fortunately, in order to fix this issue, you can simply try adding an exception for the file you want to run.
If the file is on a removable storage device, make sure the device is connected to the PC before opening your antivirus screen.
In different cases, be sure to select the correct folder location. Meanwhile, you can’t click on the file directly because you actually need to select the folder rather than the file which you want to add to the exceptions.
Fix 2: Disabling Windows Defender Temporarily
If the settings of Windows Defender are set to full protection, Windows Defender can produce some false positives, so it's normal for you to encounter a simple mistake like this.
When the problem involves Windows and Windows Defender, there is no effective way to actually run the reported file, and the only way is to disable Windows Defender completely (By following the steps).
- Type windows defender in the search bar and click Windows Defender Security Center to open it.
- Click Virus & threat protection to open it and click Virus & threat protection settings.
- Under the Real-time protection section and the Cloud-delivered protection part, switch the toggle to Off.
- Click App & browser control from the left panel, check Off under the Check apps and files part. You can also turn off SmartScreen if you think it will disturb your actions during which you wish to proceed.
Fix 3: Use Control Panel to Fix the Problem with Windows Backup
This error can also occur when you are running Windows Backup. The “Operation did not complete successfully” error message will show up when Windows Backup encounters the problematic file.
If you have tried the methods above and scanned your computer multiple times, and you're pretty sure your computer isn't infected, the false positive could be caused by temporary Internet and cached files.
Before you try to run Windows Backup again, you need to delete these files on all browsers you have used. Right now, you can follow the steps below to clear browsing data for both Internet Explorer and Edge (By following the steps below).
- Type control panel in the search bar and click Control Panel to open it.
- Choose View by: Large icons and then click Internet Options. The Internet Properties window will pop up.
- Under the General section and then find the Browsing history part. Click the Delete… button and check the browsing history you want to delete.
- Click Delete and then exit Control Panel.
- Restart your computer and check if the “Operation did not complete successfully” error message still appears.
- Click your Edge browser icon at the taskbar or search for it in the Start menu to open it
- Click the three horizontal dots at the top right part of the browser and then click Settings.
- Under the Clear browsing data section, click the Choose what to clear button.
- Keep the first four options checked and then click the Clear button to clear data.
After you finished all these steps, the “Operation did not complete successfully because the file contains a virus” error message will not pop up again.
Alternatively, you can also use command prompt to fix the problem with Windows Explorer. Check out the post.
