Also if you are running PHP, then https://github.com/nbs-system/php-malware-finder. They detected stuff (consequences of WordPress compromise, obfuscated webshells) that ClamAV doesn't complain about.

My recommendation would be to use ClamAV an open source antivirus engine. It is a versatile tool designed to detect multiple types of threats from numerous file formats and other use cases (cross-platform, integration such as mail server). Finally, it is updated on a daily basis, ensuring protection against the latest known threats. This rapid update cycle is crucial for an antivirus tool to be effective.

Linux has (free) tools to improve security and detect/remove malware: Lynis,Chkrootkit,Rkhunter,ClamAV,Vuls,LMD,radare2,Yara,ntopng,maltrail,Snort,Suricata...

There's clamAV which is open source: https://www.clamav.net/

For personal use, the most commonly used is ClamAV.

Absolutely but if the OP feels they must then they should look into the free ClamAV.

I'd go with what Bman said but second to that ClamAV is a good free option.

Ehhh, there is antivirus software for Linux, like ClamAV. Also a lot of exploits these days target browsers since its an easier attack vector. Also, malware is malware, and most servers use Linux by default. So any malware that's targeting a Linux server could target a desktop user. I don't like the whole "Haha, malware doesn't affect me because everyone targets windows". Sure, those "download now!" buttons that are targeted to gullible windows users might not work on your operating system however your OS is still vulnerable and can still be exploited by malware.
