New hacking attempt?

The link you posted is genuine, however, the screenshot is clearly a scam site trying to pass itself off as Apple. Email that screenshot to reportphishing@apple.com

For future reference, no web-based entity (Microsoft, Apple, etc) would ever know your computer has an infection of any sort nor would any company email you requesting your password to your account on their server (it's their server and they can access anything you have stored on it in most cases without your assistance.)

If you get a suspicious pop-up like that in Safari in the future and can't close the browser, simply force quit Safari and then reopen Safari while holding down the shift key on your keyboard.
