woke up to a wired security certificate untrusted thing ??

HI all so i made the mistake of closing this un-trusted certificate with the red x so wanted to know if it did anything did windows add it or anything not even sure what the heck it was, just a box that said not trusted security certificate , which is wired as it was not there when i went o bed at 1 am this morning. but does closing out with the x and not clicking on add or not trust actually trust it or anything as i certainly don't want whatever the heck it was trusted. I was half asleep when i seen it and just closed lol.

No, closing it out doesn't make it automatically trust it - just ignored it.

Awesome thanks for the quick response if it poops up again going to click not trust pretty strange i don't tend to go to sites that are bad or strange, so kinda wired that was even there.

Check your date and time if it wrong that will make all certs wrong

Date and time looks A ok 10:15 am 12/18/2017 i did get a popup one site i usually go to last night first time there, and it bypassed my pop up blocker in google maybe it came from that who knows at any rate since closing i have not seen it back.
