Avast UI fails to load

I have the Premier version of Avast.

Since yesterday, Avast says that I’m not protected, and the UI always fails to load when I click the Avast icon in the tray.

I get the following error message:

Whenever I click the green “Restart Service” button, the UI opens, but when I restart my computer I get the same error again…

What can I do?
Thanks in advance…

What avast version do you have, the latest is 18.2.2328 ?
I believe that should have resolved the Avast UI fails to load.

Have you tried an Avast Repair or a clean reinstall of avast ?

I have the latest version of Avast, and I changed the services properties according to the URL that Asyn sent.

It didn’t solve my problem, so I had to completely uninstall Avast and than re-install it.

Unfortunately, now I encounter another serious issue. When I try to run a “Smart Scan”, it crushes after a few seconds, and I get the following error:

I’m sorry that it’s not in English, my Avast interface is in Hebrew… This message says that Avast is not enabled, that something went wrong and that I’m not protected…

Have you rebooted ???
