Apparently Avast is now able to scan mails also when SSL security is enabled in the mail client, but the current changelog doesn't mention it in any way.
As usual Avast changelogs are pretty useless and pointless. Whoever writes those changelos for Avast really need to read some changelogs released by Emsisoft (for example). Maybe this way they will learn something helpful and maybe I don't have to check every items in every windows of the program after each upgrade to find out what's new.
