Spybot search and destroy…………works like a charm

Keep your own Anti-virus up to date, and check the status regularly.
Get and update several Anti-spyware solutions. I use AD-AWARE and SpyBot Search & Destroy. I use the free versions from http://www.download.com Update and run these regularly. Especially IMMEDIATELY after an unexpected pop-up.
Download and install FireFox free from http://www.mozilla.com This is a browser that is safer to use than IE. Use this for general surfing and google searching. Only use IE when you MUST have IE, such as Windows Updates.
If you have Windows XP with SP2, activate the Windows firewall and check the status. If you don’t, get Zone Alarm the free version from http://www.zonelabs.com

norton.com has a 15 day free trial thats really good

If you have your isp is SBC, you get a Internet security pack free, which includes Ant-spy software.
