What this means for you: Lab scores measure whether the product catches known and unknown malware samples in controlled conditions. Both AVG Antivirus and ZoneAlarm Extreme 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
AVG Antivirus: $0 (free) / $29.88 Internet Security first year, Free / $49.99 at auto-renewal. Same Avast engine with familiar legacy branding
ZoneAlarm Extreme Security: $44.95 first year, $64.95 at auto-renewal. Enterprise-grade firewall in consumer product
The honest playbook for both products: cancel auto-renew immediately after purchase. Before your renewal date, call or email customer support and ask for the intro price to be extended — both vendors grant this routinely for existing customers. Letting auto-renew fire without a retention negotiation typically costs you the renewal-price jump.

The feature difference reflects the products' different positioning: Same engine as Avast; classic brand positioning for older users versus Check Point firewall heritage — enterprise firewall tech at home. Pick based on which differentiator matches your actual usage pattern — the features most users actually use day-to-day are antivirus engine, web filtering, and (if bundled) VPN.
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.
| AVG Antivirus | ZoneAlarm Extreme Security | |
|---|---|---|
| Idle RAM footprint | 105-145 MB | 150-190 MB |
| CPU peak during full scan | 15-25% | 30-40% |
| Full scan duration | 12 min | 23 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.
Who Should Pick AVG Antivirus
AVG Antivirus is the right choice for: Long-time AVG users upgrading; same engine as Avast with different UI.
