Security Alert Popup every time I log in

Will someone please fix the security popup every time I log in. Or do I have a bug?

 You have a bug.                     

Bullshirt. It only happens on this site.

Well why did you ask if you had a bug?

It could still be bug. Some security software does pick up things it considers a threat but are safe. There maybe somthing Chess.com can do to fix it, but that depends on what caused it. Any idea where the popup is coming from? Browser, third party software (e.g. Virus Scanner), etc...

I only asked if there was a bug to see who the trolls would be when they answered that I have a bug.

Oh, sorry Ronnie. I guess that makes you a  troll.

BY the way, this week-long affliction suddenly stopped occurring yesterday, so thanks for all the valuable help anyway.

The security pop-up was claiming that the certificate for this site was fraudulent. It always sent not one but two pop-up windows.
