What is this?

[Jerry Jorgenson]

This isn’t a cookie, it’s a certificate warning. There was some problem with looking up the certificate. What it’s supposed to do is warn you about sites where the certificate isn’t to be trusted–which doesn’t mean the site is necessary bad, there are several reasons.

If you weren’t going to Facebook, then the site that you were at is fudging something.

thanks Jerry, the weird thing is that I was shopping online at LLBean, should I contact them?
Surely they are reputable and would not fudge something

LLBean should be reputable, but it shouldn’t put up a FB certificate either. Although you can’t get a virus on a Mac, there is malware–typically trojans–that can fool you into installing something you’d probably rather not. I suggest downloading Sophos (it’s free) and have it run a scan. If you don’t want it on later, you can uninstall it.

Thanks Jerry, I’ll try it.
MacScan was OK but still showed the pop-up.
