Heres an odd one.. I have a threat I found a few weeks back. At the time jotti or virus total showed no detections with any AV's other than Antivir and VBA32 with pure heuristics. After sending it around, 5 detect it with signitures, including Antivir. VirusTotal and Jotti show Antivir detection of this threat. Yet on my PC with Antivir running, it will not detect this threat wither either on-demand or manual scanning. I have checked most of the settings I can find, and have it set on what I believe would facilitate full scanning of it. Yet it doesn't get detected. Any tips or clues as to why this would be?
