Hi cristianojgm,
Is the avast behavior module linked to the cloud?
Yes,
Avast Behaviour Shield was originally developed by AVG.
And when I visited Avast with some fellow Evangelists in 2017, they explained to us in a presentation how Behaviour Shield works.
So I know it is using the cloud, but I don't remember the details.
Does it also work disconnected from the internet?
...
I am not sure if it doesn't work at all when disconnected from the internet.
Things can change in time, so I will try to find out.
Greetz, Red.
