How to choose an antivirus
- Verify the product and version in a current independent test.
- Compare ongoing renewal cost, not only first-year discounts.
- Check whether you need parental controls, backup, password manager or VPN.
- Keep Windows, browser and applications patched.
- Avoid running multiple real-time antivirus engines simultaneously unless vendors explicitly support it.
What independent tests do and do not prove
AV-TEST scores represent particular Windows versions, test periods and product builds. Results can change. Review AV-Comparatives as an additional independent perspective; do not treat a single ranking as a permanent guarantee.
Frequently asked questions
Is Microsoft Defender enough?
For many Windows 11 home users, it provides competent baseline protection when enabled, updated and paired with good browsing habits. Extra features may justify paid software for some people.
Should I install two antiviruses?
Usually avoid two competing always-on antivirus engines. They can conflict and slow your system. Use compatible on-demand scanners if needed.
Does antivirus stop every threat?
No. Even top-scoring products cannot guarantee protection against phishing, scams, malicious attachments or new attacks.
Sources and methodology
Recommendations are based on included features, convenience and the independent July–August 2026 AV-TEST Windows 11 results (protection / performance / usability, each out of 6). This is not a fresh lab test by MyPCWorld and should not be treated as a permanent ranking.
