This is starting to sound like two different problems. The DEP sounds like a malware problem. The attachment problem sounds like a security software problem. A deep scan by 2 or 3 top-notch online malware scanners should find the culprit in the DEP case. Specifically do a root kit scan. A thorough search through the security settings in Outlook and the settings in the email module of all installed security software will likely turn up the culprit. Look for specific settings that do not allow attachment downloading, saving or execution.

I would suggest installing the free version of MalwareBytes' Anti-malware from http://www.malwarebytes.org/, have it Update to the latest definitions database, and then run a Full Scan. It couldn't hurt to also run one or two online antivirus scans. If the problem is not a virus, then no harm done, just lost some time. BTW, from what I've read and from comments from others, I believe AVG is OK, but not one of the best free anti-virus programs. I believe that Avira and Avast are probably the two best free ones. Well, even the best anti-virus programs miss some viruses, so when you think you might be infected, try one or more free online scanners of different brands than your installed one, to be safer. You can find several by doing a google search for "free online virus scan" (without the quotes). My favorites are the Trend Micro Housecall, Kaspersky, ESET, and F-Secure. Does he save attachments by double clicking on them or by right-clicking and choosing "Save as"? Hmm, it is interesting that he can get mail ok, but just can't save the attachments. That could be at a point where the AVG tries to scan the attachment. Is AVG on all 3 computers? Are there any other security programs installed? More than one anti-virus program installed could create problems. If you get the computer clean with the above scans and the problem is still happening, it might be a good thing to uninstall AVG and install either Avira or Avast anti-virus on one of the computers to see if that helps. I would definitely do the above scans first, to make sure you are dealing with a clean PC.
