Is Windows Defender Good Enough?
Windows Defender has significantly improved since Windows 10. In independent AV-TEST evaluations, Windows Defender now scores 95–98% on malware detection — good, but slightly below leading paid antiviruses. For users who:
- Browse only trusted websites
- Never download software from unknown sources
- Do not do online banking on their PC
- Have no sensitive files on their computer
Windows Defender may be sufficient. However, for anyone who shops online, does banking, uses public Wi-Fi, or handles important files, a dedicated antivirus like McAfee provides meaningfully better protection.
Where McAfee Outperforms Windows Defender
1. Malware Detection
McAfee consistently outperforms Windows Defender in independent tests, particularly for zero-day (brand new) threats. McAfee’s AI-powered Real Protect engine detects new threats before they are in signature databases, providing an extra layer of security.
2. Web and Phishing Protection
McAfee WebAdvisor and McAfee’s browser protection provides real-time warnings before you visit phishing sites, fake login pages, and malicious download links. Windows Defender has SmartScreen which is good, but McAfee’s web protection is more comprehensive.
3. Additional Security Features
McAfee includes features Windows Defender simply does not have: a full VPN for secure public Wi-Fi use, a password manager, identity monitoring (alerts if your email appears in data breaches), and secure file shredding.
4. Customer Support
Windows Defender has no dedicated consumer support line. If something goes wrong with your security, you are on your own. McAfee customers can call +44-800-066-8910 for free 24/7 UK support.
Can I Use McAfee and Windows Defender Together?
No. When you install McAfee, Windows Defender automatically deactivates itself to avoid conflicts. This is normal and expected behaviour. McAfee takes over all antivirus protection on your PC. You do not need to manually disable Windows Defender.
Should You Upgrade from Windows Defender to McAfee?
If you do online banking, shopping, or store important personal files on your PC, upgrading to McAfee is worthwhile. The added protection of identity monitoring, VPN, and stronger malware detection significantly reduces your risk. McAfee Total Protection for 1 device costs around £19.99/year. Call +44-800-066-8910 for advice on which McAfee plan suits your needs.
