Takes less than 30 seconds. Here's exactly what to do.
⬇️ Download DefendScan (Free, 2MB)Double-click DefendScan_0.4.0_x64-setup.exe from your Downloads folder.
Click Install on the setup window, then Close when done.
⚠️ You may see a blue SmartScreen popup saying "Windows protected your PC". This is normal for new software.
Why this happens: Microsoft shows this for any app that hasn't been installed thousands of times yet. It does NOT mean the file is dangerous.
How to proceed:
✅ You only need to do this once. Future updates install normally.
DefendScan opens automatically. You'll see it in your Start Menu as "DefendScan".
Try scanning a file, checking a link, or pasting a suspicious message to see it in action.
Is it really free? Yes — 100% free during beta. No ads, no tracking.
Does it upload my files? No. Everything runs locally on your PC. Nothing leaves your computer.
Why is it only 2MB? It uses smart local analysis instead of huge virus databases. Fast and lightweight.
Will it conflict with Windows Defender? No. DefendScan is a scanner, not real-time protection. They work great together.
Does it work on Mac or phone? Currently Windows only. Mac and Android versions are planned.
