Windows 11 includes Microsoft Defender, an integrated antivirus application that protects against malware, phishing, and ransomware. Microsoft states that for many users, Microsoft Defender is sufficient for everyday risks without needing additional software, provided it is regularly updated and used cautiously. The decision to use third-party antivirus software depends on individual usage patterns and specific feature needs. Microsoft warns against running multiple antivirus programs simultaneously due to potential system conflicts and resource strain. Community opinions on platforms like the r/Windows11 subreddit indicate a general consensus that Microsoft Defender meets users' security needs effectively.

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 asserts that Microsoft Defender Antivirus is sufficient for most Windows 11 users as their sole security solution, following updates to the Windows security framework designed to counteract emerging threats. The current Windows security experience includes features such as real-time protection, cloud-delivered intelligence, smart app control, and cross-platform presence. Microsoft believes that the operating system itself is the most effective guardian of user data, embedding protections directly into the kernel to avoid performance slowdowns associated with external antivirus solutions. Despite this, the cybersecurity sector argues that specialized third-party software remains important, offering features like advanced password management and dedicated identity theft protection that Microsoft Defender lacks. The threat landscape in 2026 is increasingly driven by AI, prompting Microsoft to integrate AI into the Defender engine for proactive threat detection. While Microsoft Defender provides a robust baseline for security, a comprehensive strategy also requires good digital hygiene, strong password policies, and skepticism towards suspicious links.

Avast Free Antivirus offers real-time virus and malware protection, a Wi-Fi network scanner, a browser cleanup tool, and a basic ransomware shield. It is available on multiple platforms. Pros include core protection for free, lightweight installation, and an extensive threat database. Cons are aggressive upselling, past privacy concerns, and advanced features locked behind a subscription. Malwarebytes focuses on malware and adware detection, offering real-time protection (Premium only), a browser guard extension, and a light system footprint. It is available on multiple platforms. Pros include excellent detection of adware and a user-friendly interface. Cons are the lack of real-time protection in the free version and fewer features compared to full-suite competitors. Free antivirus software should prioritize real-time protection, coverage beyond basic viruses, a browser extension for blocking suspicious sites, and automatic updates. Free versions typically handle common threats adequately but lack advanced features and support found in paid versions. Some free tools may collect user data, raising privacy concerns. To install antivirus software on Windows 10, download it from the official website, follow setup instructions, and ensure background protection and automatic updates are enabled. Transitioning from Windows Defender is usually managed automatically by most antivirus programs. Running two real-time scanners can cause conflicts; instead, pair a primary antivirus with a secondary tool like Malwarebytes for manual scans. If a paid antivirus plan is not renewed, protection may revert to a limited mode or cease entirely. Microsoft Defender offers adequate protection but lacks additional features like a VPN or identity monitoring. Standard antivirus plans typically range from to 0 annually, with renewal prices often increasing.
