Please attach the VBox.log file (VM selector windows / Machine / Show Log...) of such a VM session.

HI Frank, i have added Vbox and VboxSVC logs for your reference. Thanks

[Frank Mehnert]

The log file shows that there is a file

C:\Program Files\View\2e1eb24\x64\prc27.2.dll

which is not properly signed. For some reason this DLL is being loaded when you start the VM. VirtualBox will not start with unsigned / wrongly signed DLLs.

Whats the solution for this, it is a bug due to latest windows security patch. As everything was working fine and all of sudden after windows patch installations it stopped working.

You need to find out where that file comes from. Could be some kind of malware. You also might want to check it's signature (right-click the file in the file manager and check the signature).
