Internet Explorer and Hotmail problem

[chauhan]

Loaded my PC today, as normal, and tried to check my email with MSN (login.live.com) and it keeps saying:

Certificate Error: Navigation blocked

There is a problem with this website's security certificate.

The security certificate presented by this website was not issued by a trusted certificate authority.

Security certificate problems may indicate an attempt to fool you or intercept any data you send to the server.

How can I make sure that the certificate is real?

Thanks.

for a start I'd use firefox instead.
