The OfficeScan Client didn't even manage to remove or quarantine the said trojan... which tell us that the OSC sucks/blows and is terribly broken.

Subj: False Positive, DNETC.EXE
I would like to report that your product detects false positives, the DNETC.EXE is a Distributed.net RC5-72 Client and NOT a trojan. This is detected as "TROJ_DISTNET.A".
It is explicitly installed on workstations to participate in the RC5-72 competition, see http://www.distributed.net/rc5/ . I have been a participant (http://stats.distributed.net/participant/psummary.php?project_id=8&id=335498) of the RC5-72 competition since 2002-Dec-07 (1383 days).
THIS IS NOT A TROJAN!
The product that reports this is TrendMicro OfficeScan (Eng/Ptn 8.310/3.765.00 DCE/DCT 3.6/363), fix your product -- it's broken.
I'll update this when I get a reply.
I uninstalled all clients, even from some development servers which are "protected" with TrendMicro ServerProtect, a sister client to the OSC that runs on workstations, the ServerProtect Client (SPC for short) didn't report anything, not even while uninstalling the said "trojan".
