Each time I open Thunderbird to receive mail Through "Mail Washer Pro" I get this message, however, the email still comes in and gets sent. Many of the incoming emails I.E. allowed adds (not spam) are missing pictures in about 60% of the senders. The rest shoe up just fine. Are they related problems or are there two different ones? I'm using Malware Bytes Premium and can't seem to find a block being caused by that.

that error is about SSL certificates being issued by folks that the product does not know. These are usually issued by anti virus companies that ask you the destroy your local security so their untrusted certificates can be used because their company would not pass the sorts of audits certifying authorities must pass.

I would suggest disabling HTTPS scanning in malware bytes and see if suddenly the images start appearing and your error messages stop. I think they probably will.
