I found this:
Customers running Norton AntiVirus 2000 V6.0 for Win95/98 are receiving a
false report of a Trojan Horse virus in the file colchng.exe when trying to
install the MSDN Library - October 1999. The manufacturer of Norton
Antivirus has confirmed that this a false report. An update to the Norton
AntiVirus definition set which fixes this problem will be made available to
customers on their website. Norton AntiVirus customers also have the option
of sending the file to the Symantec AntiVirus Research Center, using the
Scan and Deliver wizard, for a more immediate update of their anti-virus
defintion set.

Since this is a false report you can choose to ignore the message during
installation.

>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.
