Since yesterday can't open Avast, windows 10 pc, Avast Internet Security.

Noticed couldn’t open Avast. Shut down computer, opened today, still can’t open it, run as admin, doesn’t do anything. I see on startup 2 Avast AvLaunch Components. Help.

Thanks, on the second reboot, it fired up.

So, the issue you had is SOLVED?
