I read Kaspersky antivirus was compromised by Russian hackers, which provided access to the data on 400M computers. Bugs in McAfee and Panda antivirus inadvertently deleted customer’s files. Many antivirus programs themselves contain severe security vulnerabilities. I wish there was at least one good antivirus program. Many of them are like health food that contains carcinogens.
