Lots of services have "-"

[DukenukemX]

My services and startup programs stopped starting up when I restarted my computer. When I tried to manually start the service it said file not found. I found the "-" without quotes in front of C:\ or "C:\ .

I fixed it by searching the registry for -C: or -"C: and removing the "-". Was this my registry corrupting? Could a virus have done this? Nod32 scanned my system and found nothing.
