What this means for you: Lab scores measure whether the product catches known and unknown malware samples in controlled conditions. Both Norton 360 Deluxe and Comodo Internet Security sit within the range where detection isn't typically the deciding factor — your pick usually comes down to pricing model, bundle features, and whether the corporate ownership matches your trust threshold.
Pricing & Renewal Reality

Comodo Internet Security: Free / $29.99 first year, Free / $39.99 at auto-renewal. Strong free tier; unique containment architecture
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.
| Norton 360 Deluxe | Comodo Internet Security | |
|---|---|---|
| Idle RAM footprint | 180-220 MB | 130-180 MB |
| CPU peak during full scan | 35-45% | 25-35% |
| Full scan duration | 24 min | 20 min |
For users with modern hardware (2020+), the performance difference is usually imperceptible during daily use — both products idle quietly and scan without disrupting active work. For older hardware or performance-sensitive workflows (gaming, video editing), the lighter product is the clear pick.
