What is mcafee?

McAfee is a company that makes software to protect computers, phones, and other devices from viruses, hackers, and other online threats. Their main product is called “McAfee Antivirus,” which scans your device for bad software and helps keep your personal information safe.

Let's break it down

  • Antivirus engine: Looks for known viruses and malware by comparing files to a big database of threats.
  • Real‑time protection: Monitors what you do on your device and blocks suspicious actions before they cause harm.
  • Firewall: Controls incoming and outgoing internet traffic, stopping unwanted connections.
  • Web protection: Warns you about dangerous websites and blocks phishing attempts.
  • Updates: Regularly downloads new threat definitions so it can recognize the latest malware.

Why does it matter?

Every day, new viruses and hackers try to steal data, lock files for ransom, or use your device to attack others. Without protection, you could lose important photos, have your identity stolen, or see your computer slow down or crash. McAfee helps prevent these problems, giving you peace of mind while you browse, shop, or work online.

  • Smartphones and tablets (Android, iOS)
  • Small business networks and servers
