✍️ Description

New script: ClamAV. It's an unprivileged Debian 13 LXC running clamd on TCP 3310, with freshclam keeping signatures updated. Mail servers, Nextcloud, Paperless-ngx and other clamd clients can use it as a network virus scanner. You can also bind-mount storage into it and scan with clamdscan.

Drafted with Claude Opus 5.5 (Claude Code, medium reasoning), then reviewed and tested by me. Details are in the AI Assistance section.

Why Debian packages instead of fetch_and_deploy_gh_release:

• Upstream's release .deb is a bare CPack build. Everything lands in /usr/local, with no maintainer scripts, no systemd units, no clamav user and only .sample configs, and it takes ~550 MB installed. Using it would mean hand-building users, configs and units (anti-patterns 9/31).
• Debian's clamav/clamav-daemon/clamav-freshclam provide all of that.
• Debian keeps ClamAV current in stable through stable-updates, a standing exception to the freeze. Debian 13 ships 1.4.3, upstream's LTS line.
• update_script follows the existing apt-cacher-ng pattern: apt_update_safe plus a package upgrade.

TCP setup:

• debconf is preseeded (TcpOrLocal=TCP, TCPSocket=3310, TCPAddr=0.0.0.0), so the config survives package upgrades.
• Debian's clamd is socket-activated through clamav-daemon.socket, which only listens on /run/clamav/clamd.ctl. The TCPSocket setting alone left port 3310 closed in testing.
• A socket drop-in (ListenStream=3310) is written before the package install, so no daemon-reload is needed.
• TCPAddr is set explicitly because without it local clamdscan fails silently (rc=2, no message).

Testing (Proxmox VE 9.2.24):

• Ran ct/clamav.sh from this branch through the engine (unattended, default settings). It created an unprivileged Debian 13 CT (2 CPU / 3 GB / 8 GB) and every step completed.
• clamav-daemon and clamav-freshclam are active, and clamd listens on the local socket and *:3310.
• From another LAN host: PING → PONG, VERSION → ClamAV 1.4.3/…, INSTREAM with EICAR → Eicar-Test-Signature FOUND, clean stream → OK. Inside the CT, clamdscan on an EICAR file → FOUND.
• update_script (running ct/clamav.sh inside the CT): Updated ClamAV → Updated successfully!.
• TCPSocket 3310 and the socket drop-in survive apt install --reinstall clamav-daemon clamav-base. Port 3310 and both services come back after a CT reboot.
• RAM is ~1 GB with signatures loaded. The 3 GB default leaves room for ConcurrentDatabaseReload, which briefly holds two copies of the database.

🤖 AI Assistance (X in brackets)

If you used an AI tool (GitHub Copilot, Claude, ChatGPT, etc.) to write or generate any scripts in this PR, you must confirm compliance below.
Select exactly one option.

• No AI used – Scripts were written without AI assistance.
• AI was used – I confirm the scripts were built using AGENTS.md and .github/agents/pve-script-creator.agent.md as guidance, and the output has been reviewed and corrected to match those guidelines.

Please describe to which degree, if any, an LLM was used in creating this pull request. Name the model(s) used and, if applicable, the reasoning/thinking effort level (e.g. "Claude Sonnet 4.5, high reasoning, used to draft the install script, then manually reviewed and tested" or "No LLM used"). This is informational, not a penalty — but scripts that are clearly AI-generated and not further revised by the author to match CODE-AUDIT.md / CONTRIBUTING.md may be closed without review.

Claude Opus 5.5 (Claude Code), medium reasoning. It researched upstream and Debian's packaging, drafted all three files following AGENTS.md and pve-script-creator.agent.md, and ran the tests above on my Proxmox host. During testing it found and fixed the socket-activation issue (port 3310 not opening) and the silent clamdscan failure. I reviewed the scripts and this description before submitting.

📋 Additional Information (optional)

Two checklist items are deliberately not followed:

• fetch_and_deploy_gh_release/check_for_gh_release aren't used, because the app comes from Debian's repository. See the Description for why.
• Updates go through apt (apt_update_safe + upgrade_packages_with_retry), not git pull or a release fetch.

interface_port is null because there's no web UI (same as gitea-runner). The JSON notes warn that clamd's TCP port has no authentication, which matches upstream's official image.

Try this script

ct/clamav.sh, run in the Proxmox VE shell or on an Incus host:

COMMUNITY_SCRIPTS_URL=https://raw.githubusercontent.com/cisox/DevScripts/clamav \
bash -c "$(curl -fsSL https://raw.githubusercontent.com/cisox/DevScripts/clamav/ct/clamav.sh)"

COMMUNITY_SCRIPTS_URL is not optional for ct/. Fetching the ct/ script from a
branch does not tell the engine where that branch is — with bash -c "$(curl …)"
there is no file on disk for the scripts root to be derived from, so it would fall
back to upstream main and look for the install script there.

Against a core branch as well

Add COMMUNITY_SCRIPTS_CORE_URL=https://raw.githubusercontent.com/OWNER/core/BRANCH
to test an engine change at the same time. The two resolve independently.

Useful flags while testing

dev_mode=net logs every fetch with status and duration, so you can confirm the
branch is really being used. dev_mode=keep stops a failed build from deleting
the container along with the evidence.

[cisox]

Tested the command above on Proxmox VE 9.2.24 (unattended, default settings, dev_mode=net). The install script was fetched from cisox/DevScripts/clamav, the build completed, clamd and freshclam are active, and an EICAR INSTREAM over TCP 3310 returned Eicar-Test-Signature FOUND.
