Even if you use a limited, free version of a program, you'll be doing yourself a favor.The macOS, or Mac OS X system, has existed for 40 years in various forms - it’s robust, and because of its regular updates, malware developers find it hard to keep up with the changes and write viruses that will successfully infect the Mac operating system.Īpple's basic malware detection is built directly into its Mac OS X operating system. While you may think you don't need antivirus protection on your Mac, it's more important than ever now that Apple has grown so popular. And once you're infected, it super easy for other devices connected to your network to become infected, too. There are viruses out there that are smart enough to know how to hide deep in your system and work constantly to keep you from noticing it, all while performing malicious attacks. Technology has improved for the bad guys just as much as it has improved for the good guys.
You won't always know if you have a virus. If it takes much longer for your Mac to wake up than it used to, there may be something lurking in the shadows.

If this happens, you should immediately change your password to stop any more messages being sent from your account. You may also discover that your personal email or social networking sites are sending out messages that you didn't write. These ads tend to feature adult content or claim that a virus has been detected on your device and will often appear in places that you don't normally see ads.
