How McAfee Antivirus Works

McAfee’s real-time engine runs continuously in the background, analyzing every file and connection on your device. Once you activate McAfee online at mcafee.com/activate and install the app, here’s what happens under the hood:
  • Monitors files, emails, and downloads in real-time — every attachment you open and every file you download is scanned the instant it arrives
  • Blocks viruses, ransomware, spyware, and trojans — McAfee Smart AI™ performs 4+ billion scans per day to identify and neutralize threats before they cause damage
  • Runs automatic background scans — scheduled and on-demand scans sweep your entire system to catch any threats that may have slipped through
  • Sends instant alerts for threats — you receive a notification the moment a threat is detected, with clear options to quarantine or remove it
  • Updates virus definitions automatically — McAfee pulls the latest threat intelligence continuously so your protection is always current
