I've been building and maintaining computers for over 10 years(my first was a IBM PS2 in 1985), and what I use for maintenance and security I never hear of anyone else using, I retired 2 years ago at 58 went to China and stayed there,( I like it here), and there's more nasties here that at home(I think), I've been using WinPatrol to monitor what my OS is getting hammered with and Tiny personal firewall,along with Adaware and SpyBot, and Eusing Registry Cleaner,and haven't had any problems yet, plus all this is free, am I lucky or ???
