One of my user's Outlook create files with the ".com" extension when they view an e-mail that contains JPG. There's no detectable virus or trojan on this computer. However, Comodo is complaining about ".com" files being created automatically. Is there a way to change the file extension so that it doesn't create executable files?

UPDATE: This happens to ALL jpg that I receive, regardless of source.

It's still a virus - have you tried my suggestions below? Also you could contact comodo support and ask them to analyze the file for you. – Zypher Dec 18 '09 at 5:21
I'm not sure what file you want me to send to Comodo since EVERY jpg is saved with a .com file extension. – Anonymous Dec 18 '09 at 18:06

To expand on Kieran's answer (and yes that IS a virus)

  1. Make sure your virus defs are up to date and rescan
  2. Do a full system scan after you have updated virus defs
  3. Try another scanning tool, such as Stinger

I have the latest Symantec installed and it have detected no virus. I've ran Stinger (build Nov 24) and found nothing. – Anonymous Dec 18 '09 at 18:06

If viewing a JPEG results in a '.com' file being created, it's a virus.

Detected or not, it's a virus.
