CIS HIPS - Freezes Windows 10 when an alert for System Memory Access is about to be thrown

Comodo Internet Security - CIS Install / Setup / Configuration Help - CIS
#1

I was trying to launch DS4Windows (v3.2.8.0) which in turns launches an installation prompt.
When this prompt appears my computer froze.

Turning “HIPS - Silent mode (BLOCK)” ON Again, as I’ve had to do for the last two years (which makes it a bit time-consuming to make rules for new applications) I see in the Log that the first thing this app tried (using the ruleset it already had made before computer froze) was - Access Memory - System.

Is there a way to have HIPS always block Access Memory / System for unknown applications so I can run with Silent mode OFF yet still retain the option of using the application with alerts?

I should note that I have run CIS with this HIPS setting for a long time, but it was only after an update I believe from 1903 to a higher Windows 10 build that I started to get these system locks when HIPS was not set to auto-block.

I recall this freeze would also occur if I ran Chrome browser for example, and any other application that asks for System Memory access. DS4Windows was just the latest culprit, since I just started using this app and figured I’d make the rules “quicker”.

Prior to that I’d usually only get a “hang” when a fullscreen application was launched just as it took control of the screen and/or keyboard, i.e. the usual “\KsecDD, Adf\Endpoint, AsyncConnectHlp” etc would go ok, then the game would go fullscreen and freeze… couldn’t even toggle numlock on/off at this point. but if I did a power-button-press and wait 4-5 minutes Windows would finally give me an option to kill the offending process through task manager (and also require a relog, as many other processes would be killed at this point)…

But I never had a freeze while I was only using the desktop and applications back then.

Edit:
The installation prompt appears after you launch the application, as it launches itself with a -install cmd which I believe is when it tries to run the ViGEmBus driver. You get a UAC prompt at this time.

This is the x64 installation using 64-bit .NET 6.0 runtime.

Edit2: I think I can avoid this problem i the future if I make a profile with “block” on System Memory and a few other things, and just have the rest set to “Ask”.
Course this also means I have to go through all previous applications and reconfigure them with this memory block. So it would be nice if it is fixed in CIS as well :slight_smile:

Thanks for a great product by the way! I always recomend this if someone asks.

I have had this problems for years with Windows 7 in Paranoid Mode with a plethora of programs over the years. Happens regularly.
Interestingly for some software it only happens from time to time, not every time I launch it.
