Windows Defender hijack

I was on FB and a message on my message area came up, I clicked on it, and I got the old "Windows Defender" hijack-your-page scam. Can someone tell me if it's possible there's residual stuff left behind. I've been hit by this before and I just shut the computer off and restarted. Nothing appears to be there, but would there be any thing I should look for in the Task Bar? Sort of surprised Avast or Defender didn't stop this.
