I’m running updated avast free. i hear the the “threat detected” warning when im away from the comput and when i get to the computer the pop up message with what avast is flagging isn’t on the screen long enough for me to see it. i have ran several full scans and even a boot scan which dont find anything. is there a way to find what avast is flagging? the quarantine box is always empty

you can adjust popup screen time in avast settings

if you have not rebooted since popup, right click avast tray icon and select show last popup

“thread blocked” doesn’t mean it has to be a malicious file that is blocked.
It can also be a thread detected on a web-page/website that is blocked.
