DefendScan: Free AI Security for Your PC

Hey everyone! I built DefendScan after seeing AI scams increasingly target elderly family members — deepfake voice calls, fake WhatsApp messages, phishing links disguised as legitimate sites.

DefendScan runs 100% locally on your PC:

• Detects AI-generated deepfakes in photos (local ViT model)

• Scans files for malware using Windows Defender + heuristics

• Checks URLs for phishing patterns

• Analyzes messages for scam language (100+ patterns)

Zero cloud uploads. No account required. 3MB installer. Free during beta.

I'm looking for honest feedback on:

1. Does the privacy-first approach matter to you?

2. What features would make this useful for your family?

3. Any concerns about detection accuracy?

Happy to answer any questions about the tech stack (Tauri/Rust + ONNX Runtime + Windows Defender hooks) or detection methodology!
