I’m still having random BSOD on only one XP SP3 machine with 6.0.1125. All others are working great.

I have mostly AIS licenses and followed avast! support’s additional (to Tech’s advice) suggestion of deleting browser offline content and cookies before reinstalling avast! Free only this time.
It was then stable for as long as I didn’t restart the PC - about a week during which I hibernated rather than restarted the machine - which meant the Autosandbox remained inactive. However about 40 minutes after the first restart, another BSOD.
I disabled the Autosandbox 2 days ago and have had no further problems so far. (Could just be a coincidence of course.)
I’ve also uploaded the corresponding memory.dmp and am awaiting further help from avast! support.
