Webroot SecureAnywhere Antivirus takes a radically different approach to antivirus: it performs the vast majority of its scanning in the cloud, resulting in an installable program of less than 5MB and virtually zero system impact.

Cloud Scanning Architecture

Webroot’s metadata analysis engine can identify unknown malware by analyzing over 30 behavioral characteristics of a file — without needing to execute it. This approach delivers instant protection against zero-day threats while consuming minimal local resources.

Performance

Webroot is the fastest antivirus on the market by a significant margin. Our full system scan completed in under 2 minutes. The installer is just 4MB and installation takes seconds. RAM usage at idle is less than 0.5MB.

Features

• Real-time anti-phishing and anti-ransomware
• Identity Shield (real-time protection)
• System optimizer (system cleaner)
• Lightning-fast cloud scanning
• Anti-theft for mobile (premium)
• Network connection monitor

Verdict

Webroot is the perfect antivirus for users who prioritize speed and minimal system impact above all else. It’s also an excellent choice for older or low-spec PCs. The cloud-only approach means protection may be reduced in offline scenarios.
