When you enabled enhanced protection mode in HIPS settings comodo then works as a type-1 hypervisor and thus another type-1 hyervisor such as Hyper-V will not work. So disable enhanced protection mode if you need to use Hyper-V.
If you are not running anything unknown then you should be fine, but if you want to have the highest security settings that comodo offers then leave it enabled. But like I said if you really want or need to use Hyper-V then you need to disable enhanced protection mode.
Hyper-V works now even when I turned ENHANCED to ON. I think it is therefore when I uninstall Comodo and reinstall it again because when I install Comodo for the first time I had in Add/Remove Programs 2 part/thing from Comodo and when I uninstall and reinstall COmodo, there is only Comodo firewall. I do not know the name the second part of Comodo. But it was something like Comodo Internet Security. I hope you understand because it is too hard for me to translate it to English.
I did not install CIS, I installed only CF. But I noticed when CF is installed for the first time on PC there is Add/Remove Programs 2 parts from Comodo (one is Comodo Firewall and the second is something like Comodo Internet Security - but it has weird icon). When CF is uninstalled and reinstalled again 1 part is missing and it did not install it again. I do not know why. I think it is a bug.
I have similar problem.
I am using Visual Studio 2015 with Xamarin in order to create Android apps.
Before I upgrade to the latest Comodo Internet security I was able to run the Android emulator via Hyper-V without problem.
However now that I upgrade to the latest CIS I cannot run the emulator any more.
Now I get error: Could not launch ‘VS Emulator 5.7" Marshmallow (6.0.0) XHDPI Phone’ device. Exit code 10. which I find out that is caused by the Hyper-V not being able to start.
Then I unistalled the CIS and the emulator worked.
I installed CIS again and Hyper V stopped working again.
I tried disable the HIPS but Hyper-V is still not working.
I disable all the features of the CIS (Antivirous,Firewall,HIPS,…) but Hyper-V is still not working.
I terminate from the task manager the CIS but the Hyper-V is still not working.
See attachment for error.
