|Since this isnt the first time AVG has detected that exact same virus on Office disks. My first thought is its whats called a "false positive". In other words AVG is mistakenly seeing a file on the disk as a virus. AVG does that alot.|
Here is what I would do. Do an online scan of the cd/dvd. Some excellant online scanners are:
BitDefender : http://www.bitdefender.com/scan8/ie...
Kaspersky Anti-Virus Scan : http://www.kaspersky.com/virusscanner
Nod32 : http://www.eset.eu/online-scanner
Be sure to check to have it scan the cd/dvd drive and make sure the disk is in.
If 1 or 2 of the above scanners do not see the disk as infected then its highly probably that AVG is detecting a false positive.
Another option would be just to scan the file avg detects as a virus. If avg lists the path name to the file it detects as infected.
Upload the file AVG thinks is a virus to http://www.virustotal.com/ and/or http://virusscan.jotti.org/ and see what other virus scanners think.
