What is Imunify360?

Imunify360 is an all-in-one security solution built for Linux web servers. It protects your hosting account by:

• Scanning files and databases for malware
• Blocking suspicious scripts with Proactive Defense
• Managing dangerous files in quarantine
• Automatically cleaning infected code (without affecting safe content)
• Sending alerts if action is needed

You can find it in your cPanel >> Security section >> Imunify360:

How to run a Malware Scan

1. Go to the Imunify360 tool in cPanel >> Malicious tab.

2. You can run a scan manually using the Start scanning button:



3. When threats are found, you can clean, restore, view, or ignore the file - in the Actions column:

• Click Clean up to remove only the malicious part of a file:
  
  
  
  


• Restore the original version (within 14 days) if something was removed by mistake.
  
  Note: Imunify360 can try to restore a clean file version from backup (if available). You can also manually restore clean files using the AutoBackup tool in cPanel.


• View file content to inspect it yourself.


• Add to Ignore List - add file to the Ignore List and remove it from the Malicious files list.

Tip: Imunify360 also runs scheduled automatic scans each week - no need to scan manually unless you want to double-check.

How to view Scan Results

The Scan tab shows the information about all the scans performed in your cPanel account, including the scan date, folder path, the total number of scanned files, a number of threats, a number of files detected as suspicious during scanning, and actions taken for these files:



History tab: Shows every action taken - including scans, cleanups, file restores, and Ignore List updates. This helps you track what's happened over time. Logs are stored on the server for 30 days.

How to use Ignore List

Ignore List contains the list of files, databases, and directories that are excluded from Malware Scanner scanning.

You can exclude a file or folder from future scans:

• Go to Malware Scanner >> Ignore List
• Click Add new entry and enter the full path:
  
  
  
  

Imunify360 will skip these during future scans. You can remove items from the list anytime.

Note: Wildcards like /home/*/file.php are not supported.

What is Proactive Defense?

This feature blocks suspicious scripts before they can do any harm. It doesn't rely on known malware - instead, it watches for dangerous behavior (like trying to inject code or modify system files).

You can see blocked actions under the Proactive Defense tab:



Proactive Defense operates in Kill Mode on Namecheap Business servers. This is the highest level of protection - the script is terminated as soon as malicious activity is detected.

If you're sure a file is safe and want to allow it:

• Click the gear icon next to the event.
• Choose to Ignore detected rule or Ignore all rules for the file.

Note: Use the ignore options if you are absolutely certain that the action is safe.

Managing Settings

In the Settings menu, you can manage email notifications – if Imunify360 detects malicious files or suspicious actions in the account, an email will be sent to the email address specified in the cPanel settings, asking to take action.

The Try to restore from backup first option – allows to restore the file as soon as it was detected as malicious from backup if a clean copy exists.

Use backups not older than (days) – allows to set a maximum age of a clean file. File backups are stored on the server for 90 days.


By clicking on the Account icon, you can change the language of the Imunify360 software.



That's it!
