redirect in IE and firefox

Viruses and worms
1

When I search for something with google, I get the usual list. When I pick a site and click on it, my browsers automatically redirect to a site that usually has nothing to do with my initial search. I’ve cleaned the browsers with avast tools blocked some of the sites I get rediected to, but the browsers continue to redirect me.
