Do you have any recent unpXXXXXX files (where X are some numbers) in C:\Documents and Settings\All Users\Alwil Software\Avast\log (I hope I remember the path correctly...)?
Yes, I have four such files with those kind of numbers on them.
Come on Avast,
Let,s have some answers here. This is URGENT.
I sincerely hope this is not (as another poster suggested), some form of forced upgrade. If it is, that would be a shocking thing for an anti-virus company to do to it's users, i.e. make their computer unprotected without any warning.
Come on Avast, some answers please.
