Hello. I'm wondering what you think is the best anti-virus software. Right now I am using one of the more popular brands but am not very happy with it. I have found twice now that this software package not only didn't stop a virus but didn't even detect it when I did a full system scan. Could you please tell me what you think is the best and what you use and if your happy with it? I've noticed that a lot of people use Avast and that their anti-virus is free. Free would be good because I'm on a very tight budget. Much appreciated and Thanks.
