I thank you all for your efforts - it may be just a bad definition file, BUT this is part of the reply I got from SARC:

>After installing the October MSDN, I ran Norton AntiVirus (NAV 5.02-NT), and it reported that C:\Program Files\Common Files\Microsoft Shared\MSDN\1033\COLCHNG.EXE, contained a "Trojan Horse" virus. I submitted this to the Symantec AntiVirus Research Center (SARC), and they confirmed it. I rechecked the CD and it is also "infected".

>First, can anyone else, using an alternate virus checker, confirm this? Second, anyone know what COLCHNG.EXE is used for? The only reference to this I could find was in the registry, and it indicates that PID.EXE "calls" it. I could find no reference to either .EXE in the MSDN search.
