If your point is that it's entirely possible to not get a virus while running a computer without antivirus software, then you are very correct. I don't think anyone's debating that point with you. There are two issues I have with what you posted. Firstly, as I said before, your thread title insinuates that the security measures that you've listed are to replace antivirus and make running antivirus software redundant. Second, quite frankly, not running antivirus is just stupid. Yes, it's very possible to look down the barrel of a gun and not get shot in the face. But it's probably smarter to not be looking down the barrel of a gun in the first place. When you enter a car and buckle your seatbelt, do horrific pictures of car accidents flash through your mind? Probably not. So why do you buckle your seatbelt? Because it's the smart thing to do. It's silly to suggest that people are using antivirus only because they're deathly afraid of getting infected. What antivirus have you been using? Hillbilly Bob's "Git Me's Compooter Safe" security package?
