Well those reading this on this date with this problem will have the advantage of being able to try the latest beta 6.0.1270, which has fixed for the aswSp.sys bsod. See http://forum.avast.com/index.php?topic=83583.0 - Stability improvements in aswSP.sys.

So for those that did provide the dump files they contributed to getting a fix and didn’t just jump ship.
