[QUOTE=bevills1;2054905]It’s dual boot Win2k and Win98SE, and Win98SE boots with no problem. Could a boot time virus affect boot of 1 OS and not the other, and how is a boot-time virus scan done?[/QUOTE]
Not an expert here, but I think it could affect only one system. I use avast antivirus home edition with WINXP, which is freeware and the home web site says it will work with WIN98. With avast, you “schedule” a boot-time scan, then reboot. It finds trojans and viruses and you can put them in a “Vault.”
You probably have a different antivirus program installed. If you can only boot to WIN98, Open your antivirus program (whatever one it may be ) and see how you can set up boot-time, Safe Mode or other full system scan and see what happens…
I hope some of the more knowledgeable Freaks can contribute some ideas here.
