I got a message from apple care warning for virus, is it real?

Hi, I just got a message on Goole Chrome on a new window that opened automatically, saying that a virus was detected in my system. The message is supposed to come from Apple Care Protection Plan, the url looks like real, but... is it real or is it a scam?

I'm running High Sierra on a MacBook Air I just bought last week. I paste a screen capture below.

Thanks for any advice!
