Removing signature

When I send an email, it automatically sets the signature that it’s virug free with a link to Is it possible to remove this with a free license?

This is not an issue with emClient itself rather with Avast. I guess Avast is catching any e-mail sent or received from emClient, scans it for any threats and adds this mentioned signature.

Probably the paid version of Avast will remove this footprint, don’t know if there is such a version aynway. OTH, maybe there is already an option in Avast free available to switch this sig off?
