EdB,

I had the same problem. Avast 2.5.x would pop up an alert and then freeze! :cry:

I tried ā€œRepairā€ from the installer script, but it didn’t help. I finally uninstalled Avast, rebooted, ran my favorite registry cleaner (JV16Powertools), rebooted, downloaded and installed the latest version of Avast and the problem was solved. ;D

Sometimes it’s easier to just start over.
