Use a product called AVG Its Free and will help. Also use a free program called AdawareSE for spyware. Then theres also spysweeper.
This always happens to folks who dont take Security seriousely. I dont mean to sound like no one does, But just haveing an antivirus software program isnt enough. You NEED to use windows update EVERY week, or have it set to Auto update every week, You also NEED a firewall, A good one is zonealarm. Run it 24/7. Internet explorer is full of security holes, it would be a good idea to try a browser called Mozilla Firefox. It also lets you Import your Internet Explorer Favorites.
I work on ALOT of computers, and this is a common problem. Its really noones fault, But Its just a lack of security on the owners part most of the time. Always keep your Anti virus softwares Definitions up to date weekly.
For the record, Nortons is a waste of money, along with Mcafee. Use AVG 7.0 and Zonelabs Zonealarm for your firewall. Use AdawareSE for spyware and also use Spysweeper.
Sorry for the long post, But i hate to see people go through this when its so avoidable. Remember, Treat the internet like EVERYONE is out to get you. Because quite frankly, Just visiting a site or just clicking on a link(on a site, in a AOL IM or Yahoo IM will give you spyware or viruses).
If anyone needs some links i could possibly dig them up. Just PM me and ill try to find them again.
