I use FREE AVG from Grisoft. I was a bit skeptical at first, since it was free, but I found it to be very good. I had used Norton before, and I though this anti-virus would be worse, but the opposite occurred. It runs faster, and doesn't slow down my PC AND the virus definitions are just as good as Norton. I was even more convinced when a family member bought Norton to remove some virus, and Norton was not able to remove it. I told them to use FREE AVG, and the virus was gone!
