Quick Overview

The Virus Scan feature in zGuardian inspects files and content for malware, viruses, and other malicious payloads. It works in conjunction with SSL Inspection to scan encrypted traffic and provides options to bypass non-critical content types for performance optimization.

How to Use This Feature in the UI

1. Ensure SSL Inspection is enabled, as Virus Scanning requires decrypted HTTPS traffic.
2. Navigate to Security > Antivirus > Virus Scan in the zGuardian interface.
3. Enable the Virus Scan toggle.
4. Configure optional exclusions:
   • File Types to Skip: e.g., .png, .pdf, .exe
   • Content Types to Skip: e.g., video/mp4, audio/mp3
5. Click Apply Configuration to save and activate changes.

Concepts & Use Cases

• Primary Purpose: To detect and block malicious files before they reach the user device.
• Virus scanning is essential for inspecting downloadable files and attachments delivered over HTTPS.
• Exclusion of non-risk content types like images, audio, and video helps maintain performance without reducing security posture.

Note: Virus scanning is only effective for HTTPS traffic if SSL Inspection is enabled.

Troubleshooting & FAQs

• Q: Why is virus scanning not working?
  A: Confirm that SSL Inspection is enabled. Without it, encrypted content cannot be scanned.
• Q: Why are downloads slow when virus scanning is enabled?
  A: Consider excluding high-bandwidth, low-risk content types like media files to reduce inspection overhead.
• Q: Can I whitelist files from scanning?
  A: Yes. Use the file type and content type exclusion options in the Virus Scan settings.
