Rejected security certificate for Yahoo Mail by Avast

Unread post by GarthP » 2016-02-10, 09:53

I just had an FM message box about a rejected security certificate for Yahoo Mail issued by Avast. So far as I can see the certificate should be valid, it's in-date etc. I was still using FM 25.1 but have now updated to 25.2. Is this likely to be an error fixed by the new version, or something else?

Please provide as much detail as possible: exact error message, certificate details, etc.

You should honestly disable whatever causes Avast to hijack certificates.

I've responded as well (but you apparently don't check your PMs). Avast hijacking SSL/TLS connections with a generated certificate is not going to be trusted by FossaMail (rightfully so).
Disable SSL/TLS scanning in Avast. It's a really bad idea to do this.
