Frequently asked questions
Is Windows Defender good enough?
For many home users with careful browsing habits, Microsoft Defender provides solid baseline protection. Paid suites add extras such as stronger web protection, VPNs, password managers and identity monitoring.
Do Macs need antivirus?
macOS includes built-in protections (Gatekeeper, XProtect), but Macs can still get adware and phishing attacks. A reputable security app adds an extra layer, especially if you download a lot of software.
