Hi,
Searched everywhere for a solution without success.
Avast blocks/uses Intel Virtualization, when I use other softwares (MEmu for instance) that use it they say it is not enabled on the system, although it is enabled in the BIOS.
When I uninstall avast, everything works fine. after installing Avast the problem emerges again. Now i'm forced to use AVG, which I don't like, I've been using Avast for many many years now.
Any solutions anyone ? Thanks.
PS: Using the latest Avast Nitro and Windows 10 Entreprise full updated.

- Which Avast..? (Free/Pro/IS/Premier)
- OS..? (32/64 Bit..? - which SP/Build..?)
- Other security related software installed..?
- Which AV(s) did you use before Avast..?
Avast Free Latest
Windows 10 Enterprise x64 with all available updates
Nothing but built-in Windows Defender
None, always used Avast Free.

First, be sure to get rid of all remnants of your prior installed AV(s)..!!
-> https://www.avast.com/faq.php?article=AVKB11#artTitle
Then:
1. Download Avast Free Antivirus: https://files.avast.com/iavs9x/avast_free_antivirus_setup_offline.exe
2. Follow instructions: https://www.avast.com/uninstall-utility (Run this tool for all prior installed Avast versions..!!)
3. Reinstall Avast with the downloaded installer from point 1.
4. Reboot.
Nope, still same problem: no VT-x with Avast installed.
Without Avast installed or with any other AV software everything works fine.

When I asked about Intel virtualization matters a few weeks ago I was given the advice to go to AVAST Settings > Troubleshooting and untick "Enable Hardware Assisted Virtualization".
Unfortunately I have not gone any further with this I've been bogged down trying to get Windows 7 Updates to work properly for the last week, a problem not caused by but added to by AVAST which I won't detail here. But the info on the virtualization issues came from an impeccable source.

That option does not exist in Avast settings anymore.
Now, if I install Avast THEN install VirtualBox, Avast will stop using VT-x ?
-
@gennoken: thanks for info, we'll support MEme in next avast version; right now, the only way is to disable "Enable Hardware Assisted Virtualization" in Troubleshooting, because two applications cannost share VT-x.

Hi Petr, as mentioned by the OP (Reply #4), that option is gone in the settings of the latest version.

I see it was removed unintentionally :-[ -- as a workaround, you can disable 'self protection' (in troubleshooting), run regedit.exe and set Start=4 in HKEY_LOCAL_MACHINE\System\CurrentControlSet\services\aswvmm.

Oops, good to know.

Thanks, worked, virtualization enable now.

That rather depends on if you having a virtualization problem ?
If you have the recommendation was to disable the "Enable Hardware Assisted Virtualization" option in the avastUI - because that option isn't present in the current avastUI 'pk' was giving a way to disable it with a registry modification.

My problem was, I cant run any android emulator (nox/MEmu (my pc always hang when startup))and (detected by LeoMoon my vt is disabled), but when I tried that regedit solution, its run normally and great, I was just curious if I changed that aswvmm, something bad will happen to my pc? sorry noob question lol
-
That change only disables the avast hardware virtualisation, this should allow other hardware virtualization to run. Just follow pk's (avast team member) post in Reply #7 above. It is also possible to save (backup) that registry key prior to making the change.
That said I don't know if your android emulation uses hardware virtualization, presumable it does.

"I see it was removed unintentionally :-[ -- as a workaround, you can disable 'self protection' (in troubleshooting), run regedit.exe and set Start=4 in HKEY_LOCAL_MACHINE\System\CurrentControlSet\services\aswvmm."
sorry im new here and im not an expert too, and im also trying to do this fix for my emulator as well. but when i go into regedit.exe with the address above, i can't modify the values of "Start" into "4". there is an error saying i cannot write new values on it. what should I do?

You need to disable Avast self-defense first.

Additional information, not necessarily relevant to the most recent posts here but possibly useful as regards the general subject.
I gave up trying to get a W7/XP dual boot to work without XP deleting W7 restore points: believe me I've tried almost every method I found suggested for hiding the drives from each other including two registry edits.
Restore points, Windows' built in safety net, I hate anything that messes with them. As a result I decided instead to settle on using Windows 7 Pro's XP Mode which requires the use a VM. The standard recommendation is to use MS Windows Virtual PC. No XP driver troubles and no restore point problems I hoped and that proved to be the case. Everything else went well too until after I'd installed AVAST on the 'guest' XP system.
The virtualization option was unticked in Troubleshooting just as done for the host W7 system but after reboot I noticed all sorts of trouble I hadn't had before. I couldn't cut and paste without crashing the VM and the same happened every time I even tried to access a shared drive or volume. Unacceptable.
Internet research on a number of PC help forums/web sites and from a number of different users laid the blame for exactly the same issues I was having on using AVAST.
Whether it was the cause or not I could not be bothered with the hassle of an AVAST uninstall and re-install so I scrapped the whole Windows Virtual PC installation and started from scratch using VMWare Player instead of Windows Virtual PC just to remove that variable too. But this time I eschewed AVAST for the guest XP mode system and went for another lighter weight AV alongside my usual anti-malware programs.
All has being going well since - no problems.
Conclusion: in these specific circumstance ie. when using a VM the evidence suggests it would be prudent advice not to use AVAST as the AV program on the guest system.

Noob here! Cant find anything that says "Start"
I have "ControlSet001" "ControlSet002" and "ControlSetCurrent"
In there i have
aswVmm and in those i have "Enum" with the lines "Standard" "0" "Count" "NextInstance".
I also have "Parameters" with "Standard" within aswVmm.
So can someone explain what to do please?

pk, this still hasn't been resolved and put back in the avastUI.

@gennoken: thanks for info, we'll support MEme in next avast version; right now, the only way is to disable "Enable Hardware Assisted Virtualization" in Troubleshooting, because two applications cannost share VT-x.
Can you also support Nox App Player which suffers from the same issues as MEmu?
Thanks

Just wanted to say that this problem exists for Leapdroid as well.
I can't even install Leapdroid without my PC locking up and having to do a hard restart.
Avast version: 12.3.2280 (Build 12.3.3154.6)
OS Version: Windows 10 Home 10.0.14393 Build 14393
-
So... was this ever fixed or addressed? I still can't use MEMU or Leapdroid with avast and I refuse to use any other antivrius because avast is awesome.

Hi, it's fixed in the latest beta.
-
Why is avast! not getting fixed? The Virtualization was gone months ago and never fixed. Languages are broken (in installer you select English and it installs your native language anyway) for months, still no fix. What's going on!? Just because version is planned for late January 2017, current stable version shouldn't be in such broken state.
-
The last public Avast release is from August, because of AVG integration. We fixed this issue immediately - it required only minor update in our virtualization driver. However, update release was postponed. We can release an emergency update, but this compatibility issues isn't critical. There is also a known workaround in this thread.

Erm, the setting was back in build 2281, now gone again in 2282. ??? :-\
-
damn, it was accidentally removed in 2282; thanks for info!

Is it safe to disable it without side effect? What will happen if I enable hyper-v?
-
Is it safe to disable it without side effect? What will happen if I enable hyper-v?
If you enable hyper-v, we'll detect it and we won't use virtualization. Avast uses hardware virtualization to make your system more secure, it's used in sandbox, CyberCapture and anti-rootkit. Still, there're quite a lot of system without hardware virtualization, what Avast tries to do, is make the best of known technologies to protect your system.

Do you recommend to enable vt-x?

That has to be your decision. pk from Avast has already told you what the effects to your protection will be if you do.
The decision now has to be yours.
-
Do you recommend to enable vt-x?
If your CPU supports VT-x, I would recommend you turn this option on in BIOS. It may be already enabled, or sometimes Avast can enable it even if it's disabled in Bios. As I said, this technology is used by Avast to improve system protection, especially on 64-bit systems.

Back (once again ;)) in 2283. Thanks Petr.

This problem exists with BlueStacks App Player as well.
BlueStacks was very slow with Avast. Searched a lot and figured out that I should disable "Virtualization" in Avast settings to make it run fast and it worked.
Can this be supported by Avast automatically? It was very difficult to find this and change the setting
