I'm running Windows 95 and loaded this - couldn't load all of the features, started getting general protection faults, tried to enable the features (e.g.Firewall, etc) then it seized the computer up completely (thought I had a virus actually). Then couldn't get past the Virus scan in Dos mode - so, have opened in SAFE mode and uninstalled it: Hey presto! A computer that works (migod that was scary) A friend is running XP - and couldn't get his copy to load at all ..Anyone else encountered problems?
