What is the best antivirus? There's no a such one leader in this list. Each of antivirus is good in its own way and has something bad. How commandment we have been teaching that we can not work without antivirus either at home or at work. But actually possible without it. I'm working on Windows without antivirus and reinstall the operating system never had. After some years of work, I understand that the antivirus is designed for those who are not confident with their knowledge of computer security. I share my experiences to fill the gaps in your knowledge.
