Help! Can't update or install avast

Recently I noticed my avast is out of date and the automatic update is not running so I tried update it manually but it always says “unknown error”.
I tried use the “repair” tool in the installer, but it still can’t update
So I googled and decided to re-install avast, I uninstalled it in control panel then used the avastclear in safemode to clean up.
I downloaded the installer from avast official website and when I tried to re-install avast, an error showed up, and here is the log

OS is Win10 x64
In the log I noticed it can’t connect to the avast server? Could it because I recently changed my internet provider? (so far with this new internet provider I haven’t notice any other problems other than avast)
Please help me :cry:

Please (re)search before posting as what to do has been explained many times already.

Change your DNS to the one from Google and it will (or at least should) work.

I have read this on other thread in the forum and I want to try this because am having the same issues… However on the latest version of avast I just can not find this DNS setting. I read articles on how to do it but they don’t have the same GUI as my version. Do you have a link to the newest avast setting.Thanks
