Just to note.
Kaspersky found Trojan-Spy.Win32.Agent.sc inside postw32.exe ? I think it is clean file but can you confirm that ?

I checked with virustotal online,
eSafe 7.0.15.0 2008.01.10 suspicious Trojan/Worm
Webwasher-Gateway 6.6.2 2008.01.11 Win32.Malware.gen#UPX!82 (suspicious)

marked them as suspicious, but we had this before with several other files too and the reason was simply that they were upx packed. postw32 could have even another cause triggering some heuristics: it is used to post process an executable to set stack size etc. Modifing executables is probably something suspicious for virus scanners :)
