This is very odd - came across this message on three occasions visiting the site today - what is it?
You attempted to reach www.progarchives.com, but the server presented an expired certificate. No information is available to indicate whether that certificate has been compromised since its expiration. This means Google Chrome cannot guarantee that you are communicating with www.progarchives.com and not an attacker. Your computer's clock is currently set to Saturday, February 1, 2014 2:38:53 PM. Does that look right? If not, you should correct the error and refresh this page.
You should not proceed, especially if you have never seen this warning before for this site.
