F-Secure Uninstallation/Removal Tool
F-Secure Uninstallation Tool is an application that will safely remove F-Secure Service Platform 5.x, 6.x, F-Secure Anti-Virus and F-Secure Internet Security 2005, 2006, 2007 from workstations.
It does not remove F-Secure products that have been installed in an unsafe location such as c:\, c:\windows or c:\program files. That’s because it will delete the directory into which F-Secure was installed.
Note – This tool should be used as a last resort when everything else has failed. Follow this official guide before proceeding to use it.
