Uninstaller for F-Prot version 3.x
Posted by - NA - on 24/07/2014 11:00

This tool will forcibly uninstall F-Prot Antivirus for Windows versions 3.x and remove all traces of the product from the system.

This is a console program. If run on the command line, the program will be quite verbose. You can check the ERRORLEVEL after the program returns. If it is not equal to 0 then something went wrong. Refer to the output to find out what went wrong.

The program takes one (optional!) parameter, which will schedule the program file for deletion. The parameter is /selfdel - and, as mentioned, optional.

Quick instructions:

  1. Download the Automatic Uninstaller to your Desktop from the attachment below
  2. Double-click on the program icon (fpav3ex). REBOOT. F-PROT 3 should now be completely removed.

Does not work on Windows 9x/ME at the moment.


  • To run it, just double-click it from whereever you downloaded it to. However, it is recommended to pipe the output into a text file just like this: fpav3ex.exe > uninstfpav3.log
  • After running the program and the program returning ERRORLEVEL 0 (or showing DONE at the end of the output), a reboot is required. However, you may experiment to delay the reboot until after installation of FPAV6 if you are upgrading.
  • /selfdel can be combined with piping the output somewhere else.

So what does it do?:

The tool will:

  • attempt to locate the installation folder for F-PROT for Windows v3 and quit if it can't. If it can't find it in the registry it tries to find it inside %ProgramFiles%.
  • unregister the shell extension
  • locate and remove the FStopW.sys driver
  • locate and remove the update scheduler service
  • try to find running instances of FPAV3 programs (e.g. the tray icons) and kill them
  • remove several registry keys used only by FPAV3
  • auto-run registry entries for FPAV3
  • attempt to kill remaining FPAV3 processes that couldn't be killed earlier
  • search for and remove any and all shortcuts that point into the FPAV3 program root from: Quicklaunch, Startup folder, Start menu -> Program, and the Desktop folder (both for the current user and "All Users")
  • remove those directories it left behind empty (where it deleted shortcuts)
  • remove all files from the program root or schedule them for removal upon reboot if the normal removal fails
  • remove the InstallShield database left behind by the InstallShield (un)installer
  • (optionally) delete itself upon reboot

Tested with the English, Icelandic and German versions 3.16f (German: 5.16) on Windows XP. Should work flawlessly with Windows 2000 or later (see prerequisites below).


  • Windows 2000 or later. No support for Windows 9x/ME at the moment (feedback appreciated regarding this!).
  • Administrator privileges
