Hi,
I've an Avast Internet Security 17.5.2303 on a Windows 7 Ultimate desktop.
After the last upgrade the UI came very sensitive. If I scan something (file, folder etc.) the process avastui.exe will take almost all of cpu. The Sysinternals Process Explorer shows that threads by start address ucrtbase.DLL!_crt_at_quick_exit+0xb0 shares the cpu load.
If I open Protection / Antivirus I'll get "Loading" on that tab an a thread. Also the Result / Details button has same function.
Logging off and in again helps but that's not very convenient;)

Avast has been the only AV-software on these computers from the initial install for 7 years.

Repairing made no difference in my case.
I prepared for clean install by taking screen shots of some log screens (e.g. Virus Chest).
The Clean Install of Avast solved the problem on both computers.
Thank you for your help!
