Besides the World’s most popular antivirus for Windows, Avast is offering a comprehensive antivirus for Apple Mac OS X (Macintosh).

It doesn’t even require the registration, so you can just download, install and use it without any hassle.

Avast Security Pro for Mac – Is it worthy to pay extra?

Besides the free version of Mac antivirus, there is also a premium one called Avast Security Pro for Mac. The pro version offers two extra features

  • Wi-Fi Alerts – This feature will immediately notify you if someone connects to your Wi-Fi network. This helps you to keep hackers/neighbors out of your network.
  • Ransomware Shield – Ransomware shields keep your personal data from being encrypted without your permission.

For these, you need to pay for the premium version which costs $59.99 per year. Is it worthy? We would say yes as ransomware on Mac is on the rise and Avast offers solid protection against it.
