They do different jobs, so most people want both. Windows Defender is Microsoft’s excellent built-in antivirus — it stops viruses and malware, and you should leave it switched on. EverGuard is not an antivirus and does not replace Defender. It adds the thing Defender doesn’t do: AI-powered protection against phishing and scam emails inside Microsoft Outlook, plus simple PC clean-up tools. Defender is free with Windows; EverGuard is £4.99 a month.

| Disk clean-up, startup manager & shortcut fixer | No | Yes |
| Made for non-technical Windows users | General purpose | Yes, that’s the whole point |
| Price | Free with Windows | £4.99 / month |
EverGuard supports Classic Outlook on Windows 10 and 11. Gmail, IMAP and New Outlook support are on the roadmap.
After 15+ years in PC repair, the people who built EverGuard almost never see viruses any more — Windows Defender handles those. What they see instead is people losing money to a convincing fake email from “BT”, “PayPal” or their bank. That’s the gap EverGuard fills.
No. It is email protection plus PC clean-up. Microsoft Defender remains your antivirus.
No. Email checks run only when new mail arrives, on the AI side — not on your CPU.
No, it complements it. The two are designed to run together.
Risk-free for 30 days. Keep your antivirus, add scam-email protection.
