Since latest avast update I'm unable to use my Oracle VirtualBOX with 64bit OSes
and all VT-x & Nested pages options are disabled; i can't use more then 1 CPU also; and I can emulate only 32bit OSes.
I can not emulate 64bit OS, getting error
VT-x is disabled in the BIOS for all CPU modes
(VERR_VMX_MSR_ALL_VMX_DISABLED).
I suppose your new kernel mode driver is using VT-x and/or not allowing other software (such as VirtualBOX) to use hardware VT-x.
I had to uninstall avast internet security in order to be able to use properly VirtualBOX.
Can u add a switch in settings - somewhere - so that I can get use VT-x and avast at same time ?
Or can u provide a download link to a previous version of avast which hasn't got VT-x kernel stuff or whatever ?
PS: using Avast Internet Security on 64bit Win8.1 Pro ; it would seem that in 64bit win7 pro things work normally.
