Malware scanner documentation

com_malscan — Documentation

com_malscan is a backend malware scanning component for Joomla. It scans your site's files for known malicious code patterns, tracks changes against a baseline snapshot, and lets you quarantine or restore suspicious files — all from your Joomla admin panel.

1. Installation

  1. Go to System → Install → Extensions in your Joomla admin panel.
  2. Upload the com_malscan_v1.3.1.zip file you received after purchase.
  3. Once installed, find Malware Scanner in the left admin menu.

2. Generating a Baseline

Before your first scan, generate a baseline — a snapshot of your current file hashes, used to detect future changes.

  1. Go to Malware Scanner → Core.
  2. Click Generate / Reset Baseline.

Only generate a baseline when you're confident your site is currently clean — this snapshot becomes the reference point for detecting future tampering.

3. Running a Scan

  1. Go to Malware Scanner → Scan.
  2. Click Start Scan.
  3. The scan checks your files against:
    • Known malware/webshell signatures (e.g. injected eval/base64 code, known backdoor filenames)
    • Changes against your saved baseline
    • Known vulnerable extension versions installed on your site
  4. Progress is shown live; large sites are processed in batches to avoid timeouts.

4. Reviewing Findings

Go to Malware Scanner → Findings to see everything the scan flagged, with a severity rating (High / Medium) and a short description of what was matched and why.

5. Quarantine & Restore

From the Findings list, you can:

  • Quarantine a file — moves it out of its live location so it can no longer run, without permanently deleting it.
  • Restore a quarantined file — moves it back if it turns out to be a false positive.

6. Automatic Updates

com_malscan checks Joomla's built-in update system for new versions automatically. Update through System → Update → Extensions like any other component.

Requirements
