We noticed that we need to deliver guides around some known things which are possibly not known to the new users. Somehow, many we missed to talk about them since the year 2010. Anti Malware is not fully correct phrase for Linux but the meaning is obvious. Here is a usable list of Anti malware for GNU/Linux server.
Malware are programs which aims to disrupt the normal operation of a server. Virus, spyware, adware, ransomsomware are some known names of specific group of malware. They can steal private information, distort or delete personal data, control the system to use it for the purpose of Man-in-the-Middle attack, using for botnets, running DDoS attack etc.
It must be understood that, there is no general purpose anti malware, antivirus for GNU/Linux as Linux or rather modern unix systems are engineered in a different fashion. Commonly the vulnerabilities are directly patched. Of course existence of Windows like Linux virus theoretically possible but not commonly known.
We are using these listed softwares alone or in combinations for specific security, they are no way replacement of generally suggested security of your server. The likelihood of a Linux server being infected by a virus is very very low, not zero. If that is a concern, then you should understand that and determine if the business is important to you. If the business is worth more than the CPU cycles and disk I/O that it will take to scan, then you should install and use commercial solutions.
Our “anti malware” are free softwares and basically collection of scripts.
