Hello,
I saw one glitch with AvastUI.
When I click “Show Details” button in license expiration alert, avastUI opens but shows blank window (see attached image).
Once this happens, every time I open avastUI it shows blank window till I choose some categories or reboot windows.
This could be confusing to newbies…
Try to repair Avast! and you may reboot your PC after the repair.
Well, after repairing avast I clicked “Show Details” button, but it does not work (nothing happens).
After opening avastUI manually, the button starts working again but blank-window issue continues.
I disabled CIS firewall but this doesn’t solve the problem.
Anyway, thanks for the response.
