Hi guys. Current issue is with a 1GHz P3,Xp Pro, 256 ram, Nvidia GEForce, it is running very slowly (5secs to open start menu). I have seen this computer in the past and it was a very stable machine, apparently it suddenly reverted to sloth-mode about a week ago. It was riddled with mal/spy/ad ware and there seems to be some I just can't shake. Symantec AV was installed but hadn't updated for 12 months, ditched that and installed AVG and it keeps finding the same virus, variations of backdoor.hacdef. So far I have run: spybot, adaware, spy sweeper, trojan remover, pestpatrol, kaspersky and avg. They are all finding things (including some that 'eat' resources) but what I don't understand is that they are finding them repeatedly. This is a home computer that has only ever had infrequent dial-up access. Any ideas would be appreciated as always...
