Recently I switched from AVG to Avast on serveral computers because I did not like how AVG started to behave from update to update. Today I got two computers stuck on the “Avast emergency update”, during login. Just a black screen and the normal user has to do a full reset. As an admin I can kill and restart a stuck explorer which solves the problem and also shows the avast emergency update running from “runonce”.
My firewall (Comodo) will block new executables accessing the internet and ask for premission. But during login this is of course not possible because the user has not logged yet. Maybe this is related.
Why does avast use these strange and randomly named executables? What is their purpose?
