I'm a/v and f/w free. Used to run NOD32 until over a month ago, when I needed all my 1Gb of RAM for some video application. Forgot to reinstall it and when I wanted to scan my pc just reinstalled and updated it and since it found 0 (zero) viruses, I decided to remove it and keep using common sense. Of course, you HAVE to know where you go on the internet and don't click any "OK" you see on the web pages (like my cousin did a while ago and finished up reinstalling the whole system ). If you really need junk on your pc, just google for pr0n
