In IE8, When I click on a link, The page jumps to the bottom..Why?

I notice that when I click on a link, or submit data (log-on,etc) in IE8, The page will jump to the bottom, having to scroll back up (this is an annoyance on big pages).
Re-installing didn't work. Microsoft Help is useless.
Is there a fix? Could it be a virus of sorts?
Update: Thanks for the answer Nahee, But yes EVERY link this happens,And I have tried mozilla.. it crashes constantly, Thanx !
