Quarantine window unresponsive

I was installing the msys2 development environment, and while updating the packages with the msys2 pacman command, avast detected IDP.generic in the file gpg-agent.exe (I presume that this is a false positive). I was not immediately sure about the file, so I let avast quarnatine the file, but later determined that I need it for my mys2 environment to work.

When I open the avast quarantine window I get a spinning circle for about 5 minutes, during which time, the controls at the top of the window and on the left hand panel are unresponsive. Eventually the window is populated with a list of quarantined files, but all of the controls on the window remain totally unresponsive.

UPDATE:

If I wait another 5 minutes per mouse click, I can restore the file, but the quarantine window remains generally unresponsive.

Repair Avast:
