I have bought the AVG for three years now. It grabs and quarantines viruses quick! No problem with it. And well worth the money! Sometimes company's say you have a virus just so they can sell you something. If you decide to buy the AVG, you will need to remove the old virus programs first them down load AVG. I also use Firefox as my browser. I will not run a computer with out theses two. My father in law was a computer builder for years... government...so I do what he says, LOL....works for me so far!
