Please don't mistake me. I dont have malicious intentions. There is one such process created by Nortan antivirus (VpTray.exe), which runs for each and every user session. that process can not be killed by the users. I don't want to disable task manager. just want to make a process prompt an access denied message when ever an user tries to kill the process. VpTray.exe does the same.
