Paul, That alert is to indicate that the file it alerted on is a likely an MS Office document that has a PDF embedded within it. You may want to take a closer look to it as we have observed malicious payloads being distributed this way in the past.
As for what PUA category it comes under, I suppose you are referring to the old PUA categories we used to have. We are in the process of streamlining our signatures names (we will have an announcement soon). This "PUA" alert doesn't fall under any of the old PUA categories. Hope this answers your questions. Thanks, - Alain _______________________________________________ Help us build a comprehensive ClamAV guide: visit http://wiki.clamav.net http://www.clamav.net/support/ml
