Browsers all say that there is a SSL error/security cert prob and wouldn't allow me to enter websites.?

I tried going onto Google but it prevented me from entering saying that it cannot connect to the real google.com. No matter which browser I tried, there is a SSL error/security cert prob. What could be the problem?? Chrome suggested that it could be due to a connection to a new wifi network but even when I switched wifi networks, I still face the same problem.

This sometimes has to do with a wrong date being set on a computer. All certificates have an expiration date and if the computer has a seriously wrong date, that could be a problem.
