While searching a topic on Google, I ran across a link that lead to Physicsforums so I clicked the link. The next thing I knew, my computer was under massive attack. Viruses were being delivered as anti-virus warning windows began popping up. Spybots and Malware were being delivered - found over 60 in one pass. Programs of some sort were being installed. My browser opening page was highjacked. So, what happened? Why did a link leading to this forum get re-directed?
