This is one of those situations that could have a couple of possible solutions…. or not. In no particular order of importance:

1. This can happen if Sun Microsystems’ Java Runtime Environment (JRE) version 1.4.2_02 is installed and configured as the default handler for Java Applets.
Solution: install the latest release of the JRE

2. Check the date and time on your computer.

Whether or not a company’s security certificate has expired is usually not a concern for the average user. If I visit a well known and reputable site like Yahoo and get a notice that their security certificate has expired, that’s between Yahoo and the company that issued the certificate…. usually VeriSign. Disreputable sites won’t bother getting a security certificate.

You can click start > control panel > internet options > advanced tab. Scroll down to the padlock icon (the Security section) and UNcheck the following items:
- Check publishers certificate revocation
- Check server certificate revocation
- Warn about invalid site certificate
This should stop the warning notices. If the warnings persist, and if they’re coming from VeriSign, you could visit their SSL Certificate Support site and contact tech support for further information:
