I just received the same message. I hope Comcast sends an email to everyone explaining the message and what was required to fix it.
What's required to fix it is for them to update the certificate on the server.
I realize that but I don't believe everyone does so my point is for Comcast to notify everyone the problem is theirs, that we don't need to do anything to our servers, and that the problem is fixed when it is...It shouldn't be the customers who are telling everyone that its a Comcast problem and not theirs.
I just the same message a few minutes ago. I clicked on it, and it disappeared, but I don't know what will happen next. I believe there is bug in Constant Guard. Since I installed it, I get numbers instead of letters on a crossword puzzle. According to the puzzle techs, there is nothing wrong with their website, so it must be Comcast's Constant Guard.
I just installed the "secure backup and share" center yesterday. Could it have anything to do with this message? I got an email saying I would get a second email that would tell me how to access secure backup and share, once I've backed up the files; I didn't get that second email.
I just got the same message on my laptop to. I am glad its a Comcast problem and not mine. Ever since I installed their Constant Guard my computer seems like it is not working as well as it did before.
