No, it is not a heuristic more a generic detection. Maybe one of the Avast Guy can explain it a bit more detailed.
The Problem is, that it sometimes produces false alarms and you are only able to find out by scanning that file with an other scanner or by sending the file to Avast.
In your case i would tend to a false alarm.
BTW: You should enable your System restore. If you use Windows me you need a patch to enable it again, if you haven´t patched it allready.
