When I try to run F-PROT Antivirus I receive the error message: "The handle is invalid"

There are three possible reasons for this error:
  1. If you install F-PROT Antivirus for Windows on Windows NT/2000/2003/XP you sometimes need to install it twice. When you install again, select "Repair".


  2. If you have a very old version of F-PROT Antivirus for Windows and install a new version without uninstalling the old version this error may occur. See solution below.


  3. If you have F-PROT Antivirus for Windows installed on a computer running Windows 95/98/ME and upgrade to Windows NT/2000/2003/XP and install F-PROT Antivirus for Windows again, you may receive this error. See solution below.

The solution is to uninstall manually and re-install F-PROT Antivirus for Windows.
