Hi Matt,
You are very lucky! I am not sure that it is wise to use no anti-virus protection, but that is up to you. I guess if you only go to select websites and never play games or receive email through Outlook you are probably fine. And those online scanners are great. I think I have tried Panda and Trend Micro. The scans were much faster then the resident software, which usually freezes my geriatric system.

The last virus I got was a couple of years ago. I was in an online class for learning Flash. Part of the class was to participate in the discussion boards. One of the weekly board assignments was to list a few links to Flash sites that you liked. It was also part of the assignment to visit the other student’s links and critique those sites. You only had to pick a couple to actually critique, but you had to visit them all. Well, I got a virus by visiting a site that a student had posted, that had a Flash game embedded into an HTML page. Very simple game, didn’t like it and when I tried to quit the game by closing the game (.swf) window – poof - infected. Needless to say, I was not a happy camper. I was able to warn the class and the link was removed before anyone else got infected.

Those sneaky little ba*dos can be anywhere attached to anything and you can bet there are hundreds if not thousands of teens with no life, thinking of nothing better then how to get off by messing someone up. Maybe it is a hormonal thing. I would imagine that the serious inventors of such nastiness are more interested in bigger targets.

Does this sound paranoid?
