Hello, I'm having two problems with my computer that I think are unrelated. I know I have a virus because it causes pop-up ads every 2nd or 3rd time I open a browser window or go to a website. I've had this virus for at least a month. But recently, my computer has started acting wierd and freezing up when I try to view comments on YouTube. It's fine on most of the YouTube site and when I'm watching videos, but if I go to the comments page of a video my computer will freeze, the window will minimize and maximize itself on it's own, etc. I never had this problem before and near as I can tell it started happening after Microsoft auto-updated itself on my computer. The virus seems to be getting worse and now my computer often stalls when I type in a field. When I open the Task Manager during a freeze it says the CPU usage is 100%, though I don't know what that means. I'd like to remove this virus and if possible revert my system back to before the update. My computer will not let me do a system restore so it would have to be done another way. I don't know what this virus is and my Ad-Aware program doesn't detect it. I'm attaching my HiJackThis log.
