Thanks for this quick answer

so:

  • new clean install => rebooted 2 times => entering license => same bad message :cry:
  • repair => rebooted => same bad message :cry:
  • downloaded my license again => e-mail ok , avast send me again => entering this new “.avastlic” => same bad message :cry:

On the other hand , even with beautifull 30 days tried avast give me , my old issue I have with 2223 , 2225 and 2233 is already here
https://forum.avast.com/index.php?topic=175448.0

So , Can I get infected with something , corrupted registry problem ?

However , I don’t get infected by full avast scan ,latest malwarebytes , adwcleaner , JRT , Roguekiller and ZHPCleaner tests

Edit:as I said in the #17 above , I already have this issue (corrupted license)with bêta last month
all right with 2218 even with 2233 expected web shield

Edit:well , at least for license issue I went back to old 2218 working version => Update from GUI to 2233 = ok expect for web shield => Update from GUI to 2016 2241 = ok expect web shield.

I don’t know why avast forget me by clean install but I have anyway to go back to 2218 to be securised.
For the second issue , as I think I’am maybe the only one to have trouble , I’m not very optimistic for a fix :-\
