Lab Test Showdown
ClamWin Free Antivirus lab results: Not applicable (on-demand only) at AV-TEST February 2026. Not applicable at AV-Comparatives 2025 Summary Report.
HitmanPro lab results: Not applicable (second-opinion scanner) 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 ClamWin Free Antivirus and HitmanPro 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
ClamWin Free Antivirus: Free (GPL) first year, Free at auto-renewal. Free, open-source, scriptable for sysadmin/CI pipelines
HitmanPro: $24.95 first year, $24.95 at auto-renewal. Second-opinion cleanup for infected Windows machines
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.

- Outlook add-in

The feature difference reflects the products' different positioning: Open-source ClamAV engine + Windows frontend — not for typical consumers versus Cloud-based second-opinion scanner — runs alongside primary AV. 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.
| ClamWin Free Antivirus | HitmanPro | |
|---|---|---|
| Idle RAM footprint | N/A (on-demand) | N/A (on-demand) |
| CPU peak during full scan | 15-25% (on-demand) | <15% (on-demand) |
| Full scan duration | 46 min (single-threaded) | 5-10 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 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 your priorities align with that profile — and especially if Open-source ClamAV engine + Windows frontend — not for typical consumers matters for your use case — ClamWin Free Antivirus is the better pick between these two.
Who Should Pick HitmanPro
HitmanPro is the right choice for: Tech-support workflows; users needing second-opinion cleanup.
Specific strength: Second-opinion cleanup for infected Windows machines. Honest weakness to know: Not primary AV — no real-time protection (HitmanPro.Alert is separate).
If Cloud-based second-opinion scanner — runs alongside primary AV is the deciding factor in your buying decision, HitmanPro wins this comparison for your profile.
