BitDefender antivirus is an great PC antivirus software. I have found that it is equally capable, if not more so, than the AVG antivirus I have. My biggest disapproval about the antivirus is it finds a lot of false positives. False positives are when it thinks something is a virus, but it is actually not a virus. Your normal user probably will not see this problem too much, because you will not have almost as much files on the hard drive as I do. Overall, a good antivirus.
