What is that?
You should avoid letting it happen. It's unclear what you're trying to prevent, so clarify your request.
Consider checking the site again or restarting Skype (or whatever you launched). If needed, turn off the computer. Keep in mind, there’s a very low chance—about 1 in 10,000—that someone is intentionally trying to harm you. The odds suggest the problem is likely related to a certificate verification failure.
Who would think of doing something to a random person? I can't go back to check which site caused this. Back then I was using Google, YouTube, CSGolounge, Gmail, so I'm not sure. I clicked "NO", started watching a movie, reduced the volume and then the error came again. I pressed "NO" once more and it's no longer visible. I don't know what happened.
If you encounter this notice once more, open the view certificate option and take a screenshot.
I've noticed this alert on trusted platforms as well. I don't understand the reason, but it seems like a sign of careless management. Usually, it's harmless as long as you trust the site in question.
