The honest playbook for both products: cancel auto-renew immediately after purchase.

Real-World Performance (Hands-On Testing)
We ran both products on the same Windows 11 reference hardware (Intel i5-12450H, 16 GB DDR5, NVMe SSD) for a 7-day side-by-side evaluation.
| Microsoft Defender Antivirus | McAfee+ Premium | |
|---|---|---|
