Firefox Invalid Security Certificate

[johnnypok]

I have been plagued by this mysterious lack of invalid security certificates on my browsers for quite a while now. Ever since I deleted my temp folders for some extra space, or around this time, I have been receiving this error for most popular websites such as google, you tube, and Facebook which don't allow me to access it and other smaller websites which I can bypass the error.

I've heard things like maybe the time on my computer is wrong, but its correct. This is really starting to inhibit my life and I have unfortunately had to switch my main browser to Yahoo. Another thing is on the smaller websites when I bypass the invalid certificate they are usually un-formatted and look very primitive like logos are missing and the text is just on the left side going down. I can't take much more of this and need some answers please.

One last thing is that I have Kapersky antivirus, but idk if that affects this problem at all.
Thank you for reading and hopefully answering my question, my life is falling apart.🙁

not to be repetitive, but, aside from the "time", what is the "date"?

The time and date are correct, and I have noticed that internet explorer asks me about the certificate but I can still bypass it to connect to google.

Someone please help me this is destroying my life I can't do anything...

It says i may need to import a root certificate for the site but I can't find any websites that have one. Any idea of where I can find this root certificate for google websites?
