I've downloaded the latest Clamwin and virus databases. While scanning it detects and trojan for the file lame_enc.dll. This file is included in the PCWizard 2013 utility.

I then went to VirusTotal and uploaded the "lame_enc.dll" file for analysis. There were no detections .. (including Clamwin).

I then downloaded PCWizard (2013.2.12 zip version) again and rescanned using Clamwin. Again, it detects a trojan (PC Wizard\Mark\lame_enc.dll: Win.Trojan.Riskware-10 FOUND) for the file lame_enc.dll that is included with PCWizard.

So, I am at a loss to understand why the latest Clamwin database that I download detects this file as a trojan when Virus Total detects nothing.
