Operation did not complete successfully because the file has a virus: 6 Fixes

Activating a file that has a virus could infect your whole system. Therefore, antiviruses and Windows Defender don’t allow the system to open the file or run any associated programmes if an associated programme/ software can trigger a virus attack. In such a scenario, we encounter the error – Operation did not complete successfully because the file has a virus.

Possibly, this error can occur as a false alarm for known or trusted programmes. Antivirus products treat unverified and untrusted external files as a threat. Let’s check out some possible solutions to fix this issue.

Why does this happen?

There are a few possibilities for this to happen. Some of these could be:

  • A file is affected by malware.
  • A file or application downloaded from an unverified source.
  • Downloaded software is flagged as dangerous by the antivirus because the code or behaviour matches that of known malware.

Step 1: Open File Explorer and go to the file location to be excluded from a suspicion check by the antivirus. Copy the path of the file from the address bar.

sfc /SCANFILE=c:\windows\explorer.exe 
sfc /SCANFILE=C:\Windows\SysWow64\explorer.exe

Step 1: Initially open the Command Prompt application from the Start menu in Administrative mode by choosing the Run as administrator mode.
