What is Maldet? (LMD)
Maldet is a malware detector that is mostly used on servers that run Linux. It makes use of threat data from network edge intrusion detection systems to remove malware that is actively employed in assaults and generates signatures for detection.
For those in charge of shared Linux hosting servers, it will be quite helpful. A compromised account frequently has malware files and infected files inside of it. Using Maldet, you can quickly recognise the files and either remove or quarantine them.
Maldet offers a wide range of switches and options. Let’s use the example to examine all the switches and options in maldet.

maldet -a /home/?/public_html
8. -c, -checkout FILE
This command will upload suspected malware to rfxn.com for review & hashing into signatures
9. -l, -log
This command will view maldet log file events.
