Malke,

Thank you very much for your advice. My PC finally comes back.

After running Stinger, Betal.n@mm is detected. More than 100 files were contaminated by the virus, including av files and other system files. As you suggested I upgraded my Norton av and downloaded Spybot and Ad-aware. Those utilities removed 300 some files from my pooly maintained PC. What a mess!

This incident really teaches me a lesson. I'll keep your e-mail as the Bible and clean up my PC routinely.

Thanks again and Have a good weekend.

-QJ

     Hi, QJ. It certainly sounds like you've got a virus that immediately
     breaks any av installed. This could happen if you had an older
     antivirus version, weren't updating its definitions or didn't renew
     your subscription. If your XP installation was done with FAT32 (DOS
     won't see NTFS partitions), you could try F-Prot for DOS, but the usual
     way to deal with this is to:
      
     1) Take the infected machine off the Internet and any lan immediately.
     2) From a different, clean machine download Stinger here:
     
     (http://vil.nai.com/vil/stinger/)
     
     and run it in Safe Mode. Stinger is a limited virus checker, but its
     advantage is that it is standalone and doesn't need to be installed.
     3) Hope that Stinger cleans up the machine enough to be able to
     reinstall your av or install a new, current one. Update its definitions
     and do a full scan.
     4) Continue the cleaning process by removing any spyware with Spybot
     Search & Destroy (http://www.safer-networking.org) and Ad-aware
     (http://www.lavasoftusa.com). Be sure to update these programs before
     running them. These programs are free, so run them both since they
     complement each other. It is best to run antivirus and spyware removal
     tools in Safe Mode.
      
     Now, if you can't even run Stinger, you might try booting with a current
     av like Norton. You'd want the most current one out there so if your
     version isn't 2004, you need a newer one. If all that doesn't work,
     then you can either 1) take the machine to a good local computer repair
     shop and see if they can clean it up; 2) format the drive, reinstall
     Windows, reinstall programs from cd's, restore data from backups.
     
     Good luck,
     
     Malke
