Built-In Security Tools on Windows and Mac

Before buying antivirus software, it helps to know what your computer already includes. Both Windows and macOS come with built-in security features that are enabled by default on current versions.

Windows

Current versions of Windows include Microsoft Defender Antivirus as part of Windows Security. It scans for malicious software, receives regular definition updates through Windows Update, and works alongside the built-in firewall. You can open Windows Security from the Start menu to check its status.

macOS

Macs include several layers of protection, such as Gatekeeper, which checks apps before they open, and XProtect, which helps detect known malware. These run in the background and are updated by Apple.

Do you need more?

That depends on how you use your device, what other features you want, and how comfortable you are managing settings. Some people prefer a third-party product for extra features such as web filtering or multi-device management. Others find the built-in tools, combined with good habits, meet their needs.

Habits that matter either way

• Keep the operating system and apps updated.
• Download software only from official stores or developer websites.
• Use unique passwords and turn on multi-factor authentication where available.
• Back up important files regularly.
