every time i try to use google? It doesnt matter if it is google or yahoo! I try to use both of these search engines everyday and everytime i type something in, then hit enter, I will then click on the link I want. Everytime! It redirects me to some weird search engine or advertising site. I dont know if it is a virus on my computer or not. It gets very frustrating when I cant look at stuff on my computer. Please help me!!!! What can I do to fix it???
