There is the new thing going around the web called "Winfixer". It's a pop up thing and will automatically pop up on your computer and install it self. It hard to get rid of. It’s the most annoying thing ever. It puts a bunch of pop-ups on you computer, when you try to search something, you click the link and it goes to another search engine. I had to restore my computer to get rid it because the help thing I found didn't help me to remove it. If you think you have it HERE is the help thing I found on web http://forums.techguy.org/showthread.php?t=404024.
I don't know if it will work for you though. It's an awful program and people have reported it as well I haven't but I read where other people have.
