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.

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.

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.

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.

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.
