Defining “Silent Unexpected Shutdown,” 1. (n.) When CIS/Premium crashes, exits, shutdowns, or terminates without user initiating shudown and without CIS alerting user prior to shutdown.

Example: You arrive at a website that seems to suspiciously slow down your browser without apparent reason. While negotiating with the website, CIS shutdowns, crashes, exits, or terminates without an alert, warning, or prompt to you by CIS or by the OS. Your eyes are nowhere near the system tray and you are completely unaware of the shutdown. You continue to surf/ use the internet. Meanwhile, you’re not aware your computer’s security system (CIS, firewall, antivirus, etc) is OFF an no longer protecting you. You’re basically wide-open to any attack. You have just experienced a Silent Unexpected Shutdown.

This post/ thread seeks to examine this utterly undesirable behavior, to better classify its causes, its consequences, and its solutions. Is this a OS quirk? A CIS bug? Or a premeditated attack on CIS launched to infiltrate your system in the worst way possible?

If the GUI somehow shut down, you are still protected by the underlying software.

Knowing that some level of protection stays in place after a Silent Unexpected Shutdown (SUS) of the GUI, which I think refers to the white shield icon in the system tray, is a good thing. However, do you know the name of the minimal “underlying software” and can we verified that is it “actually” running (like in task manager)? That would be first priority for me. Second, I would want to understand more about the SUS of the GUI.

PS. I’ve used CIS for more than 5+ yrs. This SUS behaviour has occurred several times since I upgraded to CIS premium. I have 100K software of my system. SUS is terrifying when you discover its happened to you. Its a feeling that is similar to falling asleep at the wheel. I placed password protection on the CIS GUI to prevent unauthorized shutdown of CIS, and SUS defeated that.

The actual security software file’s name is CmdAgent.exe.
This can be confirmed running with a program such as Process Explorer.
