I let my friend borrow my computer for a while because I didn't have power back yet at my place and he fried his computer during the storm. When I got it back when I got power, I noticed a really ***** thing. There was some javascript commands added to my menu when I right-click a folder or file. Ran anti-virus and spyware in the hopes it was that but aparently it's not. It hasn't yet really done anything but I don't wanna chance it. Worst of all he was using my precious computer to watch porn and download stuff

There goes me trusting my friends with my computer, never again...
Here's a screenie of it:
Also... Explorer sometimes freezes... Gets rather annoying, he also fried my sound card
