Ok Bob that's why you didn't see the problem.
By default it is on, and causes dead laptop & possibly desktops as well.
I had to fix another laptop last night as well, it was a Leader brand laptop, brand new.
Same problem but the "other" kb that gives problems.
I'll get the kb number & post it tomorrow, I don't have it with me at the moment.

avast has a problem that is killing PC's.
It has to be fixed.
Bob it's not "Hardware acceleration" it is "hardware-assisted virtualisation".
This is as the Microsoft kb help says, it will break the PC, a known problem.
It is still happening.
Avast and Microsoft need to fix this ASAP.
Cheers NH
