For about 4 years I had no anti-virus software or firewall, didn't update windows or explorer, and had no virii. I have an old notebook running Windows 98, with a dial-up connection to a small free ISP. On startup I used to delete all services except systray, explorer & sysinject (something to do with Mijenix Fix-It). My IE security level was 'medium' plus some block on Java (I think). I never had the in-box open while downloading email, and pulled the plug out before looking in the in-box. Also I avoided clicking on spam. Eventually I got something and intalled Adaware which fixed it. Now I've got AVG and Panda and everything's dead slow. I'm just curious about why I got away with it for so long.
