Also, for those using Mozilla Firefox, I recommend adding this script blocking tool http://noscript.net/ because it stops scripts (duh ) Basically it will stop popups and any other background processes of a website from loading. Just when you visit a site, you would have to "allow" it to be able to view it properly, and occasionally some of the background processes, page widgets, plugins and javascripts and other stuff. But for peace of mind, I love it. Not saying it's gonna stop every malicious thing, but since using it, I've had no problems on the virus front.
