Certificate Error on Every Website/Browser

Hi there, I have been having an issue the last couple of days. Whenever I visit a website (about 80%) of the sites I go to regularly, I am now getting an error that "Your connection is not private". I have searched the entire internet for the answer and nothing has worked. This happens in Firefox, Safari, and Chrome....

What I have already tried/verified:

1. Date and Time are correct

2. Uninstalled browsers and reinstalled

3. Reset Keychain

4. Made sure software up to date (10.11.6)

5. Reset all browser settings to default

6. Went into keychain access and attempted to delete expired certs (deleting not an option with right click, highlighting and hitting 'delete' on keyboard, or in the Edit drop down a the top - it is greyed out).

Things to know:

My computer has also shut down a few times (before this issue) and saying it restarted because of a problem.
I have 2 admin desktops (one personal and one for work)
Work desktop seems to create the issue of restarting, as well as being slow to load when I login

I have never ever had a problem with a Mac and now I am 100% lost on how to fix this...your help would be hugely appreciated!

Picture below is screenshot of Chrome browser error in random site. Again this happens in every browser I use on 80% of the sites. My bank site and Apple site (for example) do not have this issue.

MacBook Pro (Retina, 13-inch, Mid 2014), OS X El Capitan (10.11.6)

Hello Raeanne27,

Thank you for reaching out to the Apple Support Communities. I see from your post that when attempting to visit a large percentage of websites in multiple browsers, you're receiving the following error message: "Your connection is not private". I can certainly understand why this would be a concern, and I'd like to help.

Were you able to test for this issue in another user account on your Mac? This may help to narrow down the problem a bit. You can find more information about this process here:

How to test an issue in another user account on your Mac - Apple Support

Another isolation step that I'd recommend would be to try testing for this on another Wi-Fi network while using your newly-created test user account. This will help you to determine if the problem is exclusive to the network you primarily use.

Cheers!
