I ran McAfee which found some viruses/trojans/worms and I cleaned/deleted/quarantined them. I ran Spybot. Because of my problem I couldn’t install Ad-aware or any of the other programs suggested here. I deleted a lot of adware from the "Add/Remove Programs" and the "Manage Add-ons."
If my problem was caused by a virus, Trojan, worm, or other malware, and I’ve cleaned them all, if they have already done their harm, how do I know which virus, trojan, or worm did what, and how do I fix it?
