i have a problem. i have been at my friends dad's store trying to remove spyware/adware/trojans/about:blank hijackers. i got rid of all the trojans/viruses in safe mode using ewido fully updated, trojan hunter fully updated, symantec client fully up to date, MS antispyware, adaware, spybot, xoftspy, ad aware away, cws shredder, everything all up to date, and all ran in safe mode to get rid of the stuff, it gets rid of it, but it comes back when i go back into normal windows. this is windows 2000. i want to maybe find out if the problem with the spyware keeps coming back from a registry backup windows/spyware program made and it keeps restoring it back to where all the spyware was in there. is there anyway to remove registry back-ups in windows 2000? or would this just be pointless to do?
