Windows 11 comes with several built-in security features. However, relying solely on these may not be sufficient to protect against diverse cyber threats. With cyberattacks becoming increasingly sophisticated, a robust antivirus solution remains essential.
Why Built-In Protection Isn’t Enough
Windows 11 includes enhanced security features, but these are baseline defenses. They often lack:
- Advanced behavioral detection
- Real-time ransomware prevention
- Web protection against fake sites and malicious downloads
- Identity theft safeguards
Cybercriminals now use zero-day exploits, polymorphic malware, and AI-powered phishing. The built-in defenses struggle to keep up with these threats, making third-party antivirus essential.
The Importance of Layered Security
To safeguard your Windows 11 system, a layered security approach is recommended. This means using multiple protective measures that work together to provide comprehensive security. Effective cybersecurity isn’t a single feature—it’s a strategy. The best antivirus software uses a multi-layered approach, combining:
- Real-time protection
- Behavioral analytics
- Encrypted browsing
- AI-driven threat detection
- Identity and financial data monitoring
Below, we review the top 5 antivirus solutions for Windows 11 in 2025, each chosen for excelling in a specific area.

How to Choose the Best Antivirus Software
When selecting the best antivirus software for Windows 11, consider factors such as the level of protection offered, additional features, ease of use, and pricing. Not every antivirus is a one-size-fits-all solution. Evaluating the software's impact on system performance is also essential, as some antivirus programs can slow down your computer.

- Know What You Need: Start by identifying your priorities—do you need basic malware protection, or a full suite with VPN, parental controls, and identity theft monitoring? A gamer, a business owner, and a parent may all need different features.
- Assess Performance Impact: Some antivirus programs can slow down your system more than others. Look for lightweight solutions that offer robust protection without affecting startup time, browsing speed, or app performance.
- Check Compatibility: Ensure the software supports your operating system and integrates well with your existing applications and hardware. Compatibility with Windows 11, Mac, or mobile platforms may influence your choice.
- Use Reviews and Test Runs: Consult trusted reviews, independent lab results (like AV-Test or AV-Comparatives), and user feedback. Many antivirus vendors offer free trials—take advantage of these to test usability and performance before committing.
