I don't have a firewall, or technically any antivirus software. I am on a win98 box and have been trouble free since I bought it new in 1999. I don't open spam and I run AdAware and Spybot monthly at least. Yet my parents computers are basically crippled at home (100 miles away) from virii and the like - they put Norton on one I finally wiped clean and got rid of everything, but it still runs like crap. So what is the solution?
