When you don't know what you're talking about please don't give people advice.
I think you mean either Delta IT realized they had an old compromised certificate on that site or the hackers/police/intelligence agency are no longer doing a man-in-the-middle attack on you.
Never click through such a message! (Should I say that again!?)
I'm sure I know what I'm talking about... Otherwise I would not be managing SSL certificates and a PKI infrastructure for a worldwide organization (plus a few InfoSec certifications).
If you read my message carefully, I mentioned the word
false positive. Avast and other "internet security" tools often misinterpret a certificate mismatch or any other kind of error and have a generic "revoked certificate" message...
So please read carefully before offending others.
Delta could have a bad IT reputation, but trust me, there is a very small chance that they would revoke a certificate in a production server without installing a valid one first.
