Hello,
i just did clean installation of Avast 22.8. After boot my PC is very slow and unresponsive with visual Avast broken pop-ups. I noticed in task manager, my Setpoint.exe is now has High CPU usage, which didnt had before. Closing that pop-ups needs more attempts and when I success, all high CPU activity of AvastUI.exe and Setpoint.exe is gone.
Repair and again clean installation not helped me.
I also used Avast support tool - ID:IMP8C
Win 7 64bit
Avast 22.8
Logitech Setpoint 6.70.55 64bit
Thanks for help.
Update: Today those broken pop-ups changed to Avast blocked vulnerable driver. I know about my one vulnerable driver (iqvw64e.sys version 1.3.0.7) which i update. But it not make sense why this open 5 pop-ups all at once. They cannot be closed because my PC is almost frozen at that time. It eats my whole CPU.
Another strange thing is, i have unticked "Block vulnerable kerner drives" by default.
Update 2: I just updated my vulnerable driver, so i cant provide more details about those freeezing PC pop-ups, because they no longer appear.

Hello, high SetPoint.exe CPU usage after installation: From self-defense log we can see that SetPoint.exe is trying to acquire a full-access HANDLE to our AvastUI.exe process, which of course is blocked by Avast self-defense Problem is that Setpoint never gives up and is doing this in a cycle (it is doing ~500 attempts per second). So our advise for the user is to disable Avast self-defense or just get rid of the Logitech SetPoint software.

Hello Petr,
thank you for answer. I updated my vulnerable driver, so there is no longer Avast pop-ups and Setpoint/AvastUI CPU usage is back to normal. Setpoint is no longer mentioned in self-defense log. I dont much understand why Setpoint interacted with AvastUI popup. I never had this problem before. For me is problem solved.
