Hi Vinyl -- your post makes me rethink some very recent viruses I removed from my harddrive.
I use a firewall, which I believed was pretty much the "Fort Knox" of computer security, so had no worries about viruses and such being found on my computer.
During a routine check the other day I found that my firewall was disabled

but not by me for sure. I enabled it and did some scans for adware (none found), spyware (ditto) and viruses. Found two viruses(cleaned, disinfected, deleted) in my system restore files. I run Windows ME.
The problems I had been having (computer restarts on its own whenever I access internet) (intermittent crashes after restart) have stopped.
Anyway, before I removed the viruses, I had the same "no name" program that would not close for a manual restart.
