In some instances, Chrome’s cache can interfere with Opera, so if you have both browsers installed, clear the cache on Chrome. You can also get the same error in Chrome.

If you don’t have it, clearing Opera’s cache might help.

6. Modify the registry

  1. Press the Windows key + R and type regedit.
    regedit command run window
  2. Navigate to the following path:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Attachments
  3. Double-click on ScanWithAntiVirus DWORD.
  4. Set the Value data to 1 and save changes.

By making this change you’ll disable Windows from checking if there’s an antivirus installed, so use this solution only if others don’t work.

Does Opera have a virus scan?

No, Opera doesn’t have a virus scan, but it does have a database of suspicious websites that spread malware, so you might get a warning from a browser if you visit those websites.
