Apple Care Message - Virus?

It's spam ...

Avoid phishing emails, fake 'virus' alerts, phony support calls, and other scams - Apple Support

DO NOT CLICK ON THAT LINK.

It is not legit. I haven't experienced it but my first thought would be to use the following which has an excellent reputation, to see if it will deal with the message: Free Cyber Security & Anti-Malware Software | Malwarebytes

That assumes that the message is "appearing on your screen" -- if it is just an email, ignore it.

Hi

I had the same thing pop up as a Safari window and was alerted to the fact it was likely to be scam popup as it purported to come from AppleCare and I know I had not signed up to that beyond any initial free service which came with the iMac and I didn't think the iMAC came with any anti-virus scanning software anyway. Also the screen indicated there would be problems in "1 min 56 seconds before damage permanent" again which sounded wrong as if a machine was infected any virus software would generally report it had found it (and done nothing else). Hence as per other replies I thought it a scam and killed the Safari window. Screenshot below if its of use.
