# Antivirus

Antivirus protection is your **“first-pass filter”** against malware that slips past firewalls and web-application defenses. Liquid Web supports three layers of coverage:

1. **Real-time Windows defense (ESET).** Fully managed on our end—signature updates, live monitoring, and on-demand scans are handled for you.
2. **Linux file & email scanning (ClamAV / ImunifyAV).** ClamAV ships with cPanel/WHM and can be toggled per account; ImunifyAV adds a friendlier dashboard and scheduled scans across cPanel, Plesk, and InterWorx.
3. **Comprehensive malware + WAF bundle (Imunify360).** Goes beyond signature scans with machine-learning detection, herd immunity, and automatic cleanup—ideal for multi-tenant hosts.
