I am not sure if this is a form of a browser hijacking or not but I have tried googling this and cant find a solution..

What happens is whenever I try to type a webpage name in my address bar without the www. or the .com and I hit enter this is what happens

address bar: google

I get http:///?%20google

before it would do a search and go to the default or best answer. now I get that http:///?%20 crap and then I get an error 404 page not found.. Has anyone ran into this before and what do you recommend to fix it

Thanks
