Bug Defender — Cloud-Based Antivirus
Built a cloud-based antivirus system that scans files for malware using three antivirus engines in parallel. The design follows N-Version programming — running multiple independent detection engines increases the chance of catching threats that a single engine might miss.
Tools: Python, cloud architecture, parallel processing
Repo: GitHub
Overview
Bug Defender is designed to improve malware detection reliability by combining results from multiple scanning engines rather than relying on a single signature-based tool.
Key Features
- Multi-engine scanning — three antivirus engines run in parallel on uploaded files
- N-Version programming — diverse detection approaches reduce single-point-of-failure risk
- Cloud-based architecture — scalable file scanning without local engine installation
Why This Approach
Traditional single-engine antivirus tools can miss novel or polymorphic malware. Running multiple engines in parallel and aggregating their results provides a more robust detection layer — especially useful when engines use different heuristics and signature databases.
