Today i got information from my workmate that avast! v.5.0 not detect this new variant yet, we are not sure whether this is caused by FP or avast! not release a new engine to detect this attacks?
Well given the malware name NewHeur (New Heuristic) PE (Packed Executable) that would seem to be a heuristic detection and many of the other detections on VT are generic, so there is a lot of unknowns about how it was actually detected. So not just a simple signature detection, though there are some in the VT results, but they differ widely. Some are detecting it on what seems to be the packing alone.
It wouldn’t be a new engine to detect this, but an update to an existing heuristic or generic signature assuming it is a good detection.
