That was the norm back then though. Windows 98, Mac OS 8 and 9. Yeah Windows NT 4 / 2000 were multi-user but they were targeting workstations rather than personal computing and even then it was another 5 or 10 years later before Microsoft took security seriously in their NT line (roughly midway through XP's like if I recall correctly)
Never mind that persistent internet connectivity was not the norm for most at that stage. This curtailed the power of drive by infections to a large degree.
My parents (and many others' parents too, I'm sure) know this all too well. Sometimes at parties I still have to hear about all those times I caused the phone bill to become huge because I couldn't leave the CompuServe Information Manager and IRC alone. Great times.
