Microsoft says Windows 11’s built-in 'Defender' antivirus is "usually sufficient" for most PC users: "I haven't used a 3rd party antivirus since XP"

Microsoft Defender.

In a world where bad actors are increasingly adopting sophisticated techniques to deploy malicious attacks, including general artificial intelligence to unsuspecting users, it feels like a no-brainer to have some kind of antivirus installed on your device.

Having an antivirus installed helps protect you against malware, phishing attacks, and ransomware that can give hackers unauthorized access to sensitive data. Luckily, Microsoft ships Windows 11 with Microsoft Defender as an in-box app to help curb such issues and provide users with real-time protection and advanced features designed to keep their system secure.
