This guy on AIM told me to go to this link and I did, then it somehow downloaded and ran an .EXE file hiddenly...Now I think windows media player had something to do with this because it came up but didn't do anything so I exited out of it. I thought nothing happened but then he signed me on to AIM and told me what I had in my e-mail and stuff about my computer. Luckily he was my friend and killed off the trojan. I want to know how to do this.

Don't worry I won't harm anyone.
