Hi from Chile
Thats happen to me right now the same error from Chrome page, it's the second time that did happen I reinstalled avast completely and ASZ was working fine for few days then abruptly puff, all extensions are gone. I can't erase \profile\user because I do not have any permits.
I think it's the location of the install induce the problem, I didn't install avast in my root because I do not have more space, I'd not like return to chrome, what can I do? install avast every 4 days?
