Defender with zero fps, quite impressive
End of 2025 when I completely moved to Linux on my new laptop, I removed my second TB HD which I kept for data on my old Windows desktop and ran real malware test on Windows 10 with WHHL light (WDAC ISG excluding UAC protected folders, SRP deny scripts in user folders, allowing executables and Defender on HIGH using configure defender with firewall wall hardening) and threw every malware I could lay my hands on it (for free) and NPE and HMP only found inactive remnants of intrusion attempts. The router firewall logs showed nothing funny, so I dare say it was not infected.

After two months of throwing rocks at Windows it was still functional and I had to wipe the system before bringing it to recycle collection point. So with safe hex practice Defender is a solid choice when you up his defenses with Configure Defender.
