Bitdefender Free Antivirus
Bitdefender Free gives users a solid, silent antivirus engine with real‑time scanning, customizable scheduling, quarantine management, behavioral threat detection, and phishing safeguards - without paid extras. Its minimal system drain makes it a practical safety layer for Windows PCs.
Bitdefender Antivirus Free for Windows is a lightweight, no-cost anti-malware solution that delivers essential protection without interfering with system performance or user workflows. It supports Windows 7 SP1 and newer, requiring at least 2 GB of RAM and 2.5 GB of free disk space. At its core, it provides real-time protection - filtering active processes, applications, web links, downloads, and email attachments to spot and neutralize threats as they emerge. The scanning engine adapts by monitoring behavioral patterns in real time, enabling the detection of both known and zero‑day malware. Users can run manual or scheduled scans, choosing between quick or full-system scans. The quick scan typically completes in under three minutes; full scans take approximately 28 minutes to scan several hundred thousand files. A quarantine module isolates suspicious items, giving users the option to restore or permanently delete them. Individual files can also be whitelisted to prevent future removal. The system remains unobtrusive, operating mostly in the background. It avoids unnecessary pop-ups or interruptions, notifying users only when action is required . Its footprint on CPU and memory usage is minimal, making it suitable for general use, including gaming or creative tasks. Protection extends to phishing attacks, covering deceptive websites through link analysis during browsing and email checks, though testing indicates there may be occasional misses, possibly improved with a browser extension.
