I have a problem 
It started about 1-1 and a half weeks ago. About half of the time, when I click on a site, it goes to some ad thingy! I have to go back to the search page, click on it again, and then it'll be fine.
When I look at the link at the top of the page, most of the time it will be the link of the place I want to go to. Say, if I tried to come here, the link at the top would say "http://www.finalfantasyforums.net". It used to be the same looking page, like the same layout, but each time it would have a different pic in the corner. It's hard to explain. But now it's practically anything!
I don't think it's good for my PC, and it's annoying, so what can I do to stop it
