I have a problem with deinstaling my AVG Antivirus on Windows. I tried to uninstall it with Revo Uninstaller but no luck. Here are some screenshots.
Did you try the AVG remover tools provided here?
Actually almost all antivirus vendors provide some kind of uninstall/cleanup/remover tool. Maybe they are aware that their uninstallers are crap and do often fail to remove all traces of their own product ;).
