SSL Problem

Following a problem with updating my Avast Pro (2014.9.0.2008) I uninstalled it using the Avast Uninstall tool and then reinstalled the program. Everything went well, though it seemed to take a very long time to download the installation files.

However, I’m getting the following messages (see attached images) regarding SSL issues. If anyone could help me resolve the issue I’d be grateful.

Thank you.
