If avast got into the state where it "hangs" when you attempt to invoke an update (either virus definitions or program update) you will have to manually fix it by downloading the program I mentioned.
This happened to people who tried to invoke a PROGRAM update in the last ~12 hours (from within the avast UI).
This is what happened to me.
I saw a pop up yesterday (Sunday) from Avast! saying there's a new version of the program. A few hours later, I tried to do a program update and it hung.

I'd like to know when it's all just fixed. I see many pages of issues with v7 on this forum. I don't need to upgrade if there are going to be these problems.
Would like to know when it's all smoothed out so that I don't corrupt my OS, my Chrome, my Apps, etc.
I have 6 running with virus database from yesterday...I suppose I''m fairly safe for now. Is that correct?
