.Mac scans email for virusesAll email messages sent to your Mac.com email address are automatically scanned by the mail server for viruses. If the mail server detects a virus, the virus is deleted before it reaches your Mac.
Although the Macintosh operating system is not affected by most viruses, the mail server detection process also targets Microsoft Windows-based viruses. Even if one of these Windows-based viruses were to reach your computer, because you're using a Mac, you will not inadvertently pass it along to a friend whose computer may be vulnerable to it.
