So, I've been using Bitdefender for years, but it always seems to freeze my computer when i install a game. I've finally said enough is enough and am looking for a good free antivirus.The problem is, they all seem to either display a ton of pop up ads or close down or alt tab programs to do something, which is usually display an ad. Are there any good free antiviruses that don't do that? And if not, what are some good paid ones besides Bitdefender and Kapsersky? Thanks!
