KevTech - do you mean Avast’s EHAV should be UNchecked in Win 7 by default?
No, what I meant was that win 7 does not come with vmware, virtualbox or hyper-v.
Win 8 comes with hyper-v.
I still think Avast should fix this issue. EHAV on in Avast should NOT prevent HAV in other apps, nor should it cause a bad result in the havdetectiontool.
Can the Avast tech folks advise?
Thanks,
Bump. This is bugging me.
It means that Avast must be partially disabled for hardware-assisted virtualization to work on the OS.
Why hasn’t Avast fixed this?
See if this fixes your concern:

Bob - Thanks for note. I’m not a beta kind of guy, but I’ll test the effect of Avast’s EHAV setting when this new version is actually released. (Not yet through Update Program. My Win 7 Pro 64-bit machine is sticking with version 2015.10.0.2208.)
However, the notes for this new version at the top of your link do NOT indicate that Avast addressed my issue, just that NG will now work on non-HAV x86 machines, where my issue is the opposite.
By the way, why was Minh6’s post here yesterday deleted? He posted here “Man, I have the exact same problem and your solution helped me perfectly. I couldn’t expect such an ironic uncheck in avast could solve it hahaha.”
@ glnz,
Can’t answer your question about Minh6 since I never saw his post.
pk and Spec8472 – My Win 7 Pro 64-bit machine has just updated to Avast 2015.10.2.2214. I re-enabled EHAV, rebooted and then ran havdetectiontool.exe, and now this PC now REMAINS enabled for HAV.
So - please advise - did you fix the problem, or is this coming from something else?
It might be something else because, while I had Avast’s EHAV disabled these weeks, I installed and ran XP Mode + MS Virtual PC on this Win 7 machine. From your earlier posts, maybe this somehow prevented Avast from re-grabbing and monopolizing HAV. So it’s not clear whether the good results just now are because you fixed or because the old problem can no longer come back due to XP Mode+Virtual PC having been installed while your EHAV was off.
Important to know before I update my other Win 7 PCs and consider whether to put Avast on the Win 8.1 Pro 64-bit dual-boot portion of this initial Win 7 machine.
Please advise and maybe explain a bit to the audience here (my noob self). In any case, I’m happy with these good results (so far). Thanks.
@glnz
I doubt you are still waiting to proceed with your planned updates, but I have noticed that the havdetectiontool behaved in the same way for me, but only for the first reboot. On a subsequent reboot, the tool went back to reporting that HAV was NOT active on the computer as long as I (still) had the Avast HAV setting enabled. My tested system is Win7 64, avast 2015.10.2.2214. Unlike you, I had no intervening installation of virtual systems. I’m NOT running the avast NG option, only toggling the avast EHAV switch.
Since I have no immediate need for other virtual software, I will probably go back to enabling avast HAV for troubleshooting, but will wait for another release cycle for NG due to some of the other reported issues with disk utilization, bloated backups, etc.
If someone knows of a FAQ for the NG feature that has system requirements, impacts, tradeoffs, etc., I’d appreciate a link. The support FAQ only says it runs processes virtually and improves DeepScreen scanning. Does that mean some behavior analysis occurs that recognizes and interrupts the virtual evil doings before actual damage is done, or something less magical than that? There’s just not much info I’ve run across about how NG is supposed to work, even at a relatively high level.
Is there a reason you could not use normal size fonts? May I suggest that this bug ridden beta has blocked or stopped him from adjusting the size?
Aren’t you a little late with your reply since the user has already lowered the font size to 12 ???
No forum bug just an over sized choice by the user in his original post.
Merckxist – Thanks for your post. I shall re-check on my Win 7 machine when I have a chance.
But I do NOT understand what is NG. What is it? Why is it not explained anywhere by Avast? What is it doing that’s separate from what Avast was before? How does it affect this issue?
I think Avast is blowing it. Avast’s pop-ups have become incredibly annoying - how is Avast now different from light-level malware?
And this issue makes no sense to me. Why is Avast doing ANYTHING that interferes with ANY computer feature?
There have been updates since this quote of Sept 2014.
Yes i have exactly same issue here… All my Laptops(i3,i5.i7) and Pc’s VT dissable because of this silly things… ihave to uncheck the “Enable hardware-assisted virtualization”. ijust notice when my dell i7-2670qm, 6 GHZ RAM laptop slower, i use third party software (SIW) and other software and the result are same (VT dissabled), so i check all of my laptops and computer and uncheck the avast “Enable hardware-assisted virtualization” and its all working fine again (enable). what is this?? im one of the loyal avast user and recomend to all my colleagues and friends offices since years ago,now im start doubt about avast product and start to find astep better than avast. yeapp… im not a fanatic person if find trouble in silly things but affected something huge… hope avast can be better and more see the detail next time.
Disabling it has the following effect:

Bob - what’s your point?
My point is that this should NOT be happening. Avast should NOT add a feature that INTERFERES with good operations on the PC. Or Avast should perfect the feature to MOVE OUT OF THE WAY when a good operation needs to run.
And why has Avast gone radio-silent? No fix?
Hmmm, so how would actually seeing the post have made any difference? ??? :
(point of logic)
Because Bob was asked a direct question about Minh6 post (by glnz in https://forum.avast.com/index.php?topic=162445.msg1188674#msg1188674), which apparently disappeared.
If Bob never saw it he wouldn’t know it had disappeared or comment on why it might have disappeared. Fairly logical.
I’ve just run into this problem too. Decided to clean install Windows 10 on my laptop - and reinstalled Avast, only to notice that my 64bit VM’s were not starting anymore in Virtualbox.
After a long search, I noticed this thread. But then still: I do not have an option “Enable hardware virtualization” in the Troubleshooting section! Maybe because I unchecked the “browser protection” in the installer? Anyway, it seems that even in this case, the virtualization is blocked by Avast and there is no way to switch it off.
I’m switching to another AV.
