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.

    I have a premium AVAST Pro Anti Virus but can not be downloaded and not supported on macOS?

    This is the message when I am attempting to open it;

    You can’t open the application “avast_pro_antivirus_setup_online (2).exe” because Microsoft Windows applications are not supported on macOS.

    I downloaded the avast and it told it me it was complete and I got the green check mark. I did not get the avast icon and I can’t find it to get it to run. when I tried to download it again, it told it was already installed. Just not confident it is working

    could you respond to my question. I downloaded the free avast security, but read there is also an avast antivirus. How does on download the antivirus? Pop-ups come everyday that avast has blocked some form of virus. Is there a way to hide the pop-ups. Thank you
