I've read articles saying that Ctrl+Alt+Del is an in-built Windows combination and cannot be disabled.
Basically, I'm trying to make something like an anti-virus and most antivirus tools are practically impossible to shutdown by using CTRL+ALT+DEL combination. The moment one shuts down the process, another instance runs in a way that process never ends, or if a user tries "killing" the process, it says "Access Denied".
Something like what happens when one tries terminating Avast or other antivirus programs by using Ctrl+Alt+Del
So that a malware cannot screw up the antivirus settings.
Also, I need this application to keep checking if its registry settings are being modified by a user / malware and undo it.
Thanks a lot!
PS: I plan to program my software/application in unmanaged C++**
I've found out the .NET's CanStop property, but .NET can't be trusted for it can easily be reverse engineered.
