Or like me, and go for five years without a virus scanner nor reformat, then switch over to XP cause one of your programs you developed didn't work under NT/2K/XP.... My poor Win98 install, I lament it to this day. I never had any active virii or trojans, although a few people have tried to send me some, but a quick view with the hex-editor and a raise of the eyebrow resulted in a deletion before ever running.
