That exploit is a new one, so it could be a false positive, or it could be that AVG/Defender haven't been updated for it yet.
Looking around, it looks as if there has been a false positive situation found when creating documents using LibreOffice, so I don't know if you're doing that or using Microsoft Word. That should be fixed in an upcoming update.
If you didn't create it using LibreOffice then we'll need a sample so we can submit it as a false positive report. Put it in an password-protected ZIP file and send it to us and I'll get it submitted.
In the meantime, if you make a file 'whitelist.ign2' in the VPOP3\plugins\vpop3av\db folder and add the line
to it, then the virus scanner will ignore that virus signature
