Microsoft states that the built-in security features of Windows 11 are adequate for most users, suggesting that third-party antivirus solutions may not be necessary. However, there are scenarios where third-party antivirus software can be beneficial, especially due to recent vulnerabilities in Defender. Independent testing organizations have rated Defender highly, with AV-Test placing it among the top antivirus solutions and AV-Comparatives awarding it the Advanced+ badge. Microsoft emphasizes that Defender runs continuously as part of Windows and receives updates through Windows Update, ensuring automatic protection. The company advises that additional security software may be useful for users managing multiple devices or seeking specific features like identity monitoring or parental controls.

Recent supply-chain attacks are increasingly targeting well-known software such as CCleaner, Steam games, and Notepad++, allowing hackers to distribute malware through legitimate updates. The introduction of artificial intelligence has accelerated the frequency and sophistication of these attacks, with hackers compromising developers or exploiting third-party tools to inject malicious code. Notepad++ was specifically affected by a supply-chain attack where a compromised third-party tool led to the distribution of tainted software. Attackers use various strategies, including hacking developers' credentials, purchasing access, or compromising tools relied upon by developers. Antivirus software is crucial for protecting users from malware, even from trusted sources, as modern solutions have minimal impact on system performance.

Microsoft has updated its guidance for over 500 million Windows 11 users, encouraging them to evaluate their security measures. The company asserts that Microsoft Defender, its built-in antivirus software, is adequate for most users, providing protection against potential risks from the moment the PC is powered on. While Microsoft acknowledges that its default protections are usually sufficient, it also notes that the decision to use third-party antivirus solutions depends on individual usage patterns and desired features. Users managing multiple devices, sharing devices with family, or seeking additional services like identity monitoring may consider third-party options. However, Microsoft warns that adding extra security tools can complicate system performance and incur unnecessary costs. The perception of built-in protection has evolved since the Windows XP and Windows 7 eras, with Windows 10 and 11 reinforcing the reliability of Microsoft Defender. Despite this, the guidance is not expected to significantly impact the third-party antivirus market, as testing has shown a variety of excellent options available for users looking to enhance their security.
