The bottom line

ClamAV catches known viruses but misses more than Norton or Defender. No suspicious behavior detection -- only recognizes threats it already knows. Open source but maintained by Cisco (US, government contracts). Code is auditable and forkable if Cisco misbehaves.

Findings by concern
Data Sharing 1/4 LOW 1 finding
⚫ mediumregulatory findings vs firmware analysis
Open source but maintained by Cisco (US, government contracts). Code is auditable and forkable if Cisco misbehaves.

What they claim: ClamAV is independent open-source software.

What we found: Maintained by Cisco Talos since 2013 Sourcefire acquisition. Cisco: US company, government contracts. But GPL-2 means fully auditable, community can fork.

Security 1/4 LOW 1 finding
⚫ mediumfirmware analysis vs policy claims
ClamAV catches known viruses but misses more than Norton or Defender. No suspicious behavior detection -- only recognizes threats it already knows.

What they claim: ClamAV provides adequate malware protection.

What we found: Lower detection than commercial AV. No behavioral analysis, no heuristics, no ML. Signature-based only. Not designed for desktop real-time. Adequate for known malware on servers.

Honesty 1/4 LOW 1 finding
✔️ lowpolicy claims vs app permissions
Most private antivirus but it's a command-line tool for technical users. Need something that 'just works'? Look elsewhere.

What they claim: ClamAV is usable antivirus for all users.

What we found: Command-line, no polished GUI, no real-time desktop protection. ClamTk basic Linux GUI. Not practical for non-technical users.
