Avast keeps shutting down its protection shields itself?

Avast Free Antivirus / Premium Security

Hi,

After the last update of avast free version, on one computer it keeps shutting down its own protection shields.
We need to activate them manually over and over again, but this keeps on happening.

What can we do to make it work properly again please?

Thanks!

Have you tried a new clean install?
