next wednesday my avast will expire but I did not get any notice yet, how long before the expiration date they send a message? In case I do not get it what I have to do?
Hi…
I’m not sure if Alwil sends out notices for the home version, if this what you have. I think they do for the professional version but again I’m not completely sure. ???
If you have the Home version, go here and fill out the necessary information…

Then wait a bit and check your e-mail for the key (from Alwil.) Then follow the instructions of this video tutorial here…

If you have the professional version, please contact Alwil at the “sales” address here…

They should be able to help you. Entering that key is the same process as described in the video. 
Hope this helps you.
May God Bless you!
