Annoying virus/malware/something

[MDanger]

I have a bit of a problem. I ran an executable (I know I'm an idiot) that I thought was legit, and according to my AVG 8.0 Internet Security program didn't contain any threats or viruses. Sadly that wasn't the case. As soon as I ran it I saw the command prompt pop up, some text flashed by and I was taken to a google web search for the world of warcraft sex video.

Now everytime I open IE or any other program I get an error message that pops up and tells me that my Windows Vista files are corrupted and I should download some antispyware software. It pops up about 5 times even while spamming the cancel button. So far the AVG hasn't found any malware or viruses.

Any idea what this could be?
