Bitdefender Antivirus Free vs Intego Antivirus for Windows: Side-by-Side Comparison (2026)

Bitdefender Antivirus Free

Small businesses and individual users on a tight security budget should pick Bitdefender Antivirus Free for its behavior-based malware detection, which catches zero-days before signature updates arrive. The vendor's 2,300+ employee team and Romanian headquarters mean this isn't a garage operation; the product has shipped real-world ransomware blocks across Android, Windows, and macOS simultaneously. Skip this if you need EDR with threat hunting or centralized management across dozens of devices; Bitdefender Free is endpoint protection only, built for single-user or small-team deployments where you're your own admin.

Intego Antivirus for Windows

Startups and small teams on tight security budgets should pick Intego Antivirus for Windows for its behavioral analysis engine, which catches zero-day threats without requiring the tuning overhead that signature-heavy competitors demand. The real-time malware detection and Web Shield for phishing combined with automatic threat updates mean you're protected without constant admin attention. Skip this if you need EDR visibility into user behavior or threat hunting capabilities; Intego prioritizes blocking over investigation.
