Uninstall the Social2Search browser addon from your computer.

It appears to be intercepting connections to web sites you visit, probably to inject its content into web pages. In the process, it is inserting its own invalid SSL certificates into HTTP connections.

A human-readable version of the certificate is below -- the "issuer" of the certificate is what led me to Social2Search:
