is necessary to see content. I use flash, Divx, Quicktime (no silverlight) and if those programs cant run the content at a website then I move on. I only download stuff from Cnet or other established sites. I never get things from omglolsuperdriverwarehouse.com or any other stupid website. If I get a popup, it gets ALT-f4'd or task manager killed. I never click on unsolicited redirected screens. L2surf and you don't need malware. That or get a Mac. There is no malware or viruses on the mac. I surf with NO worries whatsoever on a Mac.
