No, it's really not that I don't trust you, and I am sure the same can be said about the other users
Then again, chances are you could have been infected yourself without noticing, so even if you just have the best intentions, this does not 100% exclude the chance a virus could have slipped your check.
Anyway, what's really strange is the fact that all of a sudden there's this report.
I finished installing the CD on my test system and indeed it is missing the file (I blame NAV's quarantine for this), so the cleanup script does not run properly (I think, was getting a lot of errors, but I couldn't find any remains on the disk...).
Because of this I manually copied cmdow.exe into the respective directory (can you confirm if %cdrom%\OEM\bin is the right place?).
I also run a manual scan on the file.
Lo and behold, NAV did not detect any threat!
The file is absouletly clean...
Auto-Scan also did not detect any infection when I copied the DP files over from another PC.
It only alerted me during the slipstream process, which is even more strange, because this is the first time it would do so.
