As I vanished today in attempt to help my brother move I left my computer on for my nephew to play on it. I come back to see that google.com is now replaced by tube8. I'm not exactly sure whats wrong with it, it seems to be a redirection I've also checked the page options and it still says google.com.

P.s. A system restore is not working, I'm using chrome, and I'm also on xp.
Also all url searches lead into Tube8.
