Hi Slomo,

When you go to a website, are you getting an error message something like this:
“There is a problem with this website’s security certificate. The security certificate presented by this website has expired or is not yet valid.”

The Solution:
There are a few different possible solutions for this website security certificate problem. I’d suggest that you start at the top of the list and work your way down.

1. Check the website address.
Website security certificates are configured to very specific website addresses. If you typed in the address using http:// but not, www, try using www. It could be that the security certificate only applies to the www address.

2. Check your computer’s clock.
Website security
certificates sync up with your computer’s clock. Old computers in particular
run the risk of having a dead CMOS battery—the watch battery in your computer
that keeps its system clock ticking. Click the clock in the system tray and
selectChange
date and time settings to correct any issues.

You can reset the clock by:
For most Windows users:

1. Click on the time and date in the notification area in the bottom right-hand corner of your screen.
2. Click on “Change date and time settings …”
3. See if the clock is set right and change it if need be.

For Windows 8 users:

1. From the Start Menu Charms click Settings.
2. In Desktop Settings, click “More PC settings”.
3. In PC Settings, click General to check and reset the time if necessary.

3. Check into the site.
There are times when websites do not update their security certificates. If it is a company or institution you have a relationship with, contact them and explain the problem. In other cases, it might be best to look for alternative websites.


Website security certificates are designed to keep users safe. Sometimes users might encounter alarming security certificate messages. These are usually cleaned up quickly by following the steps above.

I hope this helps.

Regards,
Lokesh.
