Solve : Invalid security certificate for Yahoo mail w/ IE8 and FF, also Comodo warning?

Answer»

I attempted to log in to my Yahoo Mail account using Firefox v3.6.10 and received this message from FF.

Quote

This Connection is Untrusted
You have asked Firefox to connect
securely to login.yahoo.com, but we can't confirm that your connection is secure.

Normally, when you try to connect securely,
sites will present trusted identification to prove that you are
going to the right place. However, this site's identity can't be verified.

What Should I Do?

If you USUALLY connect to
this site WITHOUT problems, this error could mean that someone is
trying to impersonate the site, and you shouldn't continue.

login.yahoo.com uses an invalid security certificate.

The certificate will not be valid until 1/4/2006 11:09 AM.

(Error code: sec_error_expired_certificate)


Also, soon after this same time, Comodo firewall notified me of an intrusion attempt from another PC and asked whether or not to trust this. I clicked block.
Note; I've working out of town and have been staying at a hotel for ~ 5 weeks using their WIRELESS AP. (There are several 802.11g wireless AP's in this area - 4 truck stops & 6 motel/hotels). I have seen this Comodo firewall WARNING a few TIMES lately and always clicked block.

Why is this happening? What should I do?
