To update the maldet use the below commands.

maldet –update-ver

maldet –update[/i]

To scan the files.

maldet -a /home/username/

It will scan all the files and provide you the output.


To scan all user uder public_html paths under /home*/ this can be done with:

[email protected][~]# maldet –scan-all /home?/?/public_html

To scan the same path but the content that has been created/modified in the last 5 days:

[email protected][~]# maldet –scan-recent /home?/?/public_html 5

To scan but forget to turn on the quarantine option, you could quarantine all malware results from a previous scan with:

[email protected][~]# maldet –quarantine SCANID

If you wanted to attempt a clean on all malware results from a previous scan that did not have the feature enabled, you would do with.

[email protected][~]# maldet –clean SCANID

If you had a file that was quarantined from a false positive or that you simply want to restore (i.e: you manually cleaned it), you can use the following:

[email protected][~]# maldet –restore config.php.2384
[email protected][~]# maldet –restore /usr/local/maldetect/quarantine/config.php.2384
