Not sure how this happened, I think I was trying to view a video and it asked me to download a codec and stupidly I did and it installed this trojan. I can't seem to remove it with Spybot, everytime I do and I rescan it, it's back along with a few additional ones. Whenever I try to open a folder, it just opens up my browser and takes me to a Google search with methods to remove it. It's kind of misleading. What do I do?
