This may be a false alarm, but...
My AVG v2012 has found what it thinks are two malwares in
examples\exampl01\resdlg\resdlg.exe - Dropper.Tiny.E
and
examples\exampl01\3dframes\3dframes.exe - Win32/Heur
I just downloaded these from your official US Site, installed and scanned on a XP machine.
Thanks for checking.
Its a false report. Go to this link. http://www.masm32.com/board/index.php?board=52.0
AVG will even detect itself as malware... :bg
