Surprisingly, after installing Bitdefender Total Security, he found some malicious files that AVG premium wasn't able to detect. That itself is a very good indicator that this antivirus software is indeed better than the previous one I used. Also, I noticed that it is almost invisible. I hate it when my previous one updates in the middle of a presentation. The pop up is annoying. Very annoying. Using Bitdefender, it almost never bothered me.
