Can you please specify your CPU and OS?

I can confirm that with that option enabled by default, my VM ran much much slower, UI was slowly rendered. Switched off the option in troubleshoting -> reboot -> the VM worked flawlessly again like nothing happened

Please fix it. We don't want to uncheck that option but we have to do so to regain the speed of other apps

Thank you Evjls, the CPU should handle nested virtualization without problems. What is your virtualization software?

Can you please provide logs from failed VM startup: it should be present in the folder where the VM files are stored, in the Logs subfolder

Hello, I think I have the same problem even with a completely different hardware than the other of the topic The problem occurs with all of the virtual machines, with both VMware hypervisor or virtual box. I performed the minimum avast installation and also the only component web protection shows the same problems, the virtual machines will slowly start and lower performance.

igor and Spec -

What's the story?  When are you sending an update that will fix this (again)?

Others are posting in this forum with the same problem.

Thanks.

Hi glnz, I am not able to reproduce your issue, using XP mode without any issues with aswVmm on very similar HW. But starting next version, aswVmm will not use virtualization mechanisms if XP Mode installation is detected.

Spec - thanks for fast response.

But ...

1)  When Avast doesn't use hardware-assisted virtualization (HAV), is Avast weaker? 
2)  If Avast is weaker without HAV, how?  What risks are greater without HAV?
3)  If Avast is weaker without HAV, and you can't change that, then I would prefer to have the choice I have now:  Leave HAV enabled in Avast until I need to use XP Mode (or other virtual mode), then turn off Avast's HAV manually in "Troubleshooting" while I'm doing a virtual, and turn HAV back on manually when I'm done.  In that circumstance, please do not eliminate this choice.

Kindly give us some detail here.

Of course, what we all want is for Avast to be as strong as possible but not interfere with how we use our PCs.  It's a shame your team can't make that work.

Thanks for helping.

Avast is a bit weaker without virtualization as it is used in self-defense, sandbox and antirootkit. But don't worry about detection abilities of standard shields (FS, WEB), it should perform very same even without virtualization.

Spec - that sounds -- well -- not great but not too bad.

However, if Avast cannot make its HAV "get out of the way" automatically, then I would still prefer to keep Avast's HAV turned on and have the option to turn it off when I'm doing something virtual.

Please do NOT get rid of it entirely.

I got slammed with this today.
Avast auto updated with whole new UI.
Using vmware player 12.5.4, disable HAV and it's fine now.
