Most the anti-malware for Linux is aimed at Enterprise/Corporate level stuff.
For example Bitdefender used to have a Linux version of their free antivirus for home users, but they discontinued it.
On the other hand, if you’re a business customer, they have a lot of paid Security Endpoints for Linux.
Generally, as it stands, most real quality security for Linux setups is genuinely aimed at businesses, not individuals, sadly.
I’d say the biggest, most glaring hole is that, much like in Windows, most users don’t really understand the file system and user and group permissions.
Linux, as an OS, requires a lot more on the users part in understanding basic security right out of the gate.
