Antivirus One Pro 3.4.4 for Mac is the premium tier of Antivirus One, the Mac App Store security app from Trend Micro, the Japanese cybersecurity company. Unlike Trend Micro's full Antivirus for Mac suite sold on its website, Antivirus One is a sandboxed App Store app focused on scanning your Mac and removing what should not be there.

The app itself is free to download from the Mac App Store, and basic scanning is included. The Pro-level protection, including full virus removal, is unlocked through auto-renewing in-app subscriptions, historically offered on monthly and yearly plans, so it is not a free full version and current prices should be checked in the App Store listing.

Key Features

  • Quick Scan, Full Scan and Custom Scan modes for chosen folders and drives
  • Real-time monitoring against adware, ransomware, spyware and other Mac malware
  • Virus Cleaner removal tools, unlocked with the paid in-app subscription
  • Web Threat Protection to help block malicious and phishing websites while browsing
  • Regular virus database updates from Trend Micro's global threat research network

How to Download

  1. Download from the official site
  2. Use Trend Micro's Antivirus One for Mac section there to reach the official Mac App Store listing.
  3. Install it from the App Store, open it, run a first scan, and subscribe in-app only if you want Pro removal features.

Is Antivirus One Pro free?
Downloading Antivirus One is free and you can scan your Mac, but removing viruses and the advanced Pro protection require a paid auto-renewing subscription. Subscriptions renew unless cancelled in your App Store account settings.

How is this different from Trend Micro Antivirus for Mac?
Antivirus One is the lighter, sandboxed App Store app centred on scanning and cleaning. Antivirus for Mac, sold on trendmicro.com, is the broader suite with extra features such as camera and microphone monitoring and Pay Guard.
