My PC has been acting pretty funny lately, literally claiming that every web certificate I come across is invalid. I've even reformatted the thing, and I continue to have the problem. This is across IE, Firefox, and Chrome? What's going on and how can I fix it?

Is there a possibility that somebody is intercepting your communications? – nhinkle♦ Dec 11 '10 at 20:21

  • Make sure your computer's clock is set correctly. X.509 certificates have "start" and "expire" dates.

  • Open the same website on two different computers (the other can be at work, school, whatever) and compare the certificate information (subject, issuer, fingerprint).
