[FEATURE] Centralized ClamAV Signature Distribution

[maneeshaxyz]

Summary

Implement a centralized ClamAV signature distribution system where our central server acts as the authoritative source for virus definitions, distributing updates to all Silver instances automatically without relying on individual sysadmin intervention.

Why is this feature needed?

Currently, each Silver instance would independently manage ClamAV signature updates via freshclam. This approach has several issues:

• No control over when updates happen across deployments
• Inconsistent signature versions between instances
• Reliance on sysadmins to manage updates at each site
• No visibility into which instances are up-to-date
• Potential for outdated signatures if freshclam fails silently

We need to force signature updates from a central source to ensure:

1. All Silver instances stay current with virus definitions
2. We control update timing and can test signatures before distribution
3. Compliance and audit requirements are met (knowing which instances are updated)
4. Zero-day threats can be addressed quickly across all deployments
