    Lab Test Showdown

    Norton 360 Deluxe lab results: 18/18 at AV-TEST February 2026. Gold Real-World Protection, Silver Overall Performance, Silver Advanced Threat Protection at AV-Comparatives 2025 Summary Report.

    ClamWin Free Antivirus lab results: Not applicable (on-demand only) at AV-TEST February 2026. Not applicable.

    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 ClamWin Free Antivirus 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

    Norton 360 Deluxe: $49.99 first year, $119.99 at auto-renewal. Complete bundle + LifeLock restoration specialists (US)

    ClamWin Free Antivirus: Free (GPL) first year, Free at auto-renewal. Free, open-source, scriptable for sysadmin/CI pipelines

    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.

    Norton 360 Deluxe feature set:

    • Unlimited Secure VPN
    • LifeLock Identity Theft Protection (US)
    • 50 GB Cloud Backup
    • Dark Web Monitoring
    • Parental Controls

    ClamWin Free Antivirus feature set:

    • ClamAV engine (Cisco Talos)
    • Scheduled scans
    • Explorer context-menu integration
    • Outlook add-in

    The feature difference reflects the products' different positioning: Best full bundle — antivirus + unlimited VPN + LifeLock identity + cloud backup versus Open-source ClamAV engine + Windows frontend — not for typical consumers. 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.

    Norton 360 DeluxeClamWin Free Antivirus
    Idle RAM footprint180-220 MBN/A (on-demand)
    CPU peak during full scan35-45%15-25% (on-demand)
    Full scan duration24 min46 min (single-threaded)

    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 Norton 360 Deluxe

    Norton 360 Deluxe is the right choice for: US users needing identity protection; multi-device households.

    Specific strength: Complete bundle + LifeLock restoration specialists (US). Honest weakness to know: Renewal shock ($49.99 → $119.99); heaviest CPU of top-5.

    If your priorities align with that profile — and especially if Best full bundle — antivirus + unlimited VPN + LifeLock identity + cloud backup matters for your use case — Norton 360 Deluxe is the better pick between these two.

    Who Should Pick ClamWin Free Antivirus

    ClamWin Free Antivirus is the right choice for: IT pros, build pipelines, mail/file-server scanning — NOT typical home users.

    Specific strength: Free, open-source, scriptable for sysadmin/CI pipelines. Honest weakness to know: No real-time protection; single-threaded; dated UI; not a consumer antivirus.

    If Open-source ClamAV engine + Windows frontend — not for typical consumers is the deciding factor in your buying decision, ClamWin Free Antivirus wins this comparison for your profile.
