A PUA detection on ClamAv/ClamWin is not an indication of a virus. PUA detection is optionally selected by the user, and it is just informative--nothing else. What the PUA detection indicates is that the file is packed with a packer frequently used to pack/obfuscate/hide malware. There are also PUA signatures for malware tools, scripts, etc. Because of this, Clam AV will not adjust/correct/drop a PUA signature.

I notice that the PUA detection is a little bit out of favor now--I don't see it as often as I used to among AVs.

If the detection bothers you, you can exclude the filename.extension from ClamWin's scans or delete the PUA selection in the advanced tab.

Regards,

The PUA is detected by the online multi-virus-detection-program sites.
My local copy of ClamWin, on the disktec.zip I downloaded in August 2010, instead says:

BUT, on a fresh download today, it says:

The online scanners probably have PUA detection enabled on Clam--the average user probably does not need PUA enabled, as it could scare them needlessly. Since you had no detection on the last scan, it looks like maybe a false positive was corrected.

Always keep ClamWin updated to the latest engine, as older engines may register false positives when they can't completely process an enhanced signature, and each new version has additonal enhanced signatures.
