Virtual desktop does not protect files

Hello

I,ve started doing some tests on Virtual desktop-Comodo internet security latest version using Task Manager and Process Hacker.
The following result using Process Hacker was that i was able to delete files while in it just by restarting explorer.exe (even though i was getting an error that that file was not on desktop or other location is because the file was already deleted) and the other was to kill kiosk.exe using Process Hacker to completely exit the virtual desktop without a password.
Using Task manager the only vulnerabilty was to kill all Comodo from the tasks or the third one in order to completely exit from virtual desktop.
In my opinion Comodo should have something to block virtual desktop from accesing Task Manager
Thanks

Most or all can be finalized by processhacker (before you say that a trusted application), the same codes used in advanced tools with processhacker, for example, the codes of these programs are used to circumvent security suites and anti-cheats…

Were you running PH in Virtual Desktop or in the normal system?
