Project description:
"I want to launch a subscription-based antivirus product for desktop and mobile. I am not a coder and need an experienced team or freelancer to design, develop, and deliver the complete software solution.

The goal is to create a reliable, lightweight, and user-friendly antivirus app that can scan, detect, and quarantine malware, with a backend system to manage subscriptions and updates.

Scope of Work:

1. Desktop Application (Windows and macOS)

Integrate a proven antivirus engine (white-label/OEM or licensed third-party).
Features: manual scan, scheduled scan, real-time protection (optional), quarantine, virus definitions update.
Subscription verification: the app must check user license before allowing full functionality.
Simple, clean UI for non-technical users.

2. Mobile Application (Android initially, iOS optional)

Scan apps and files for malware using licensed engine.
Optional safe browsing and anti-phishing features.
Subscription verification integrated with Google Play / Apple App Store billing.

3. Backend / Cloud Infrastructure

Host servers for license management, update delivery, and optional cloud malware checks.
Automated subscription billing and renewal system.
Secure API with authentication and HTTPS encryption.

4. QA & Security Testing

Test on multiple OS versions and devices.
Use safe test malware (EICAR) for detection testing.
Fix all bugs and ensure zero crashes.

5. Documentation & Handover

Full technical documentation for maintenance.
User guides for desktop and mobile.
Deployment instructions for updates and backend management.

Skills Required:

Desktop app development (C++, C#, or Rust)
Mobile app development (Android / iOS)
Experience integrating antivirus engines (white-label or OEM solutions)
Backend development (Node.js, Go, Python, or similar)
Cloud infrastructure (AWS, GCP, Azure)
Security & QA testing

Deliverables:

Fully functional desktop and mobile antivirus apps
Secure backend subscription management system
Technical and user documentation
Deployment scripts and update mechanism
Source code repository (Git) access

Budget & Timeline:

Budget: Open for discussion
Expected delivery: 1 month

Additional Notes:

I prefer freelancers who have experience working with antivirus software, white-label engines, or security applications.
If you have suggestions for better design, architecture, or licensing options, I welcome professional input.
Emphasis on usability, security, and reliability." (client-provided description)
