If you have access to another machine with a virus scanner you can try hooking up the drive that's infected. Otherwise you might try this out http://antivirus.about.com/od/securitytips/a/bootsectorvirus.htm
I tried the SYS approach, but it didn't work. However, in spite of the data risk, I think Ill try the fdisk /mbr approach. I might have to wait until this weekend because I won't get to access the computer until then at the earliest. Thank you!
