What our users say
“I uninstalled my previous antivirus because it killed my render times. MalwareFox is silent, invisible, and my Adobe apps finally run at full speed again.”
Freelance Designer
“I just want security that shuts up and does its job. I installed this on my work laptop six months ago and haven’t had to think about it since. No nags, no drama, just protection.”

Why MalwareFox?
We answer to our users — not shareholders.
Honest Pricing
The price you pay today is the price you keep at renewal. $24/year, always. No first-year discount that doubles at renewal like the big names.
Zero Data Trading
We sell software, not your browsing data. Zero logs kept. Unlike some “free” competitors, your privacy is not our business model.
Lean by Design
Under 50 MB RAM. Under 1% CPU. Deep scans run only when your PC is idle. You’ll forget it’s even there — until a threat shows up.
Frequently Asked Questions
Everything you need to know before you download.
Where does the 99.3% Lab Protection Score come from?
MalwareFox is powered by the award-winning K7 Computing core engine. The 99.3% protection score reflects rigorous, independent testing of this core engine by AV-Comparatives. We combined their enterprise-grade threat detection with our lightweight, zero-distraction interface to give you the best of both worlds.
How does MalwareFox work?
Download, install in under 60 seconds, and register for a free trial or paid license. Run your first scan and MalwareFox quietly protects your PC in real-time. After the trial, manual scanning stays free forever.
Does it replace Windows Defender?
Yes. MalwareFox registers as your primary antivirus and takes over protection from Windows Defender.
Will it slow down my PC?
No. MalwareFox uses less than 50 MB of RAM and is built to run silently in the background — even on older hardware.
What happens after the 15-day trial?
Real-time protection and virus definition updates stop. You keep the on-demand scanner free, forever. Upgrade anytime to restore full protection.
Is it safe to install? How do I uninstall?
MalwareFox is 100% clean — no bundled software, no adware. Uninstall anytime from Windows Settings → Apps, just like any other program.
Do you sell my data?
No. We sell software, not data. Zero browsing logs are kept. Read our privacy policy for details.
