Yes. Don't.

I wouldn’t recommend using anti-virus software. It usually creates a lot more overhead, plus it usually mimics existing solutions already in linux. The only viruses I have ever caught using an anti-virus software on Linux are the test viruses to see if all is working fine.

Anyway, here’s my 20+ enterprise experience recommendations with Linux :

• enable secure boot: will disable launching non-signed kernel modules (prevent root kits)
• enable firewall: and only allow ports you really need.
• SELinux: it is getting better, and it will prevent processes to access resources out of their scope. It can be problematic if you don’t know it (and it is complex to understand). But if it doesn’t hinder you, don’t touch it. I do not know AppArmor, but it is supposed to be similar.
• disable root over ssh: or only allow ssh keys, or disable ssh altogether if you do not need it.
• avoid using root: make sure you have a personal account set up with sudo rights to root WITH password.
• only use trusted software: package managers like apt and rpm tend to have built in functionality to check the state and status of your installed software. Use trusted software repositories only. Often recommended by the distro maintainers. Stay away from use this script scripts unless you can read them and determine if they’re the real thing.

Adhering to these principles will get you a long way!

Do you have any antivirus recomendations for Linux.

Install all applications from your package manager.

Don't run things as root.

Don't visit sketchy websites.

Run an ad-blocker that isn't owned by an advertising company.

There are anti viruses that run on GNU/Linux like ClamAv and kaspersky but they actually do not target the machine they run on or at least they are not so useful. Their intention is to stop the spread of malware.

In general, you just need to install softwaref uaong the package manager from trusted sources that are usually the defaults of your distribution and not input your password when you are not expecting it.

When copying commands to the terminal, most terminals will warn you if you are copying a command that requires root privileges.

That said for the operating system, apply it to the browser as well by being eclectic on what extensions you install and voila. 99.99% guaranteed malware free.

You don't need one if you know what you are doing but there's ClamAV

Most antivirus software are just root level tools to harvest your data, that pretend to help

I don't understand why we keep telling new users that it is useless to use an antivirus on Linux. For people with computer knowledge, sure. However more widespread Linux adoption will mean more casual users will start using it. Most of them don't have the "common sense" that is often mentioned ; these users will eventually fall for scams that tell them to run programs attached in emails or random bash scripts from the internet. The possibility is small, but it's not zero, so why not protect against it?

1. Do not run a root account for regular stuff. This is a lot less common now since most distros require you to create a non-root account during install and a lot of the systems annoy you if you're running as root, but you'd be surprised by the sheer number of people who use accounts with UID 0 daily. This may also be caused by """more experienced""" friends/family setting it up that way to try cutting corners regarding access rights, but the bottom line is: don't be that person. Use root when necessary only.

2. Get into the habit of not blindly running every command you see online or trying every trick you read/hear, at least not on your main system. Try to setup a VM (or multiple) for the purpose of trying stuff out or running something you're not sure what the impact might be.

3. Keep your system updated, from kernel to userland.

4. Get into the habit of reading news regarding exploits, malware and the responses for them. You don't need to become an infosec professional or even understand what they actually do. What is important is for you to learn what to avoid and when something really bad is discovered so you can update as soon as possible.

These 4 steps are arguably more important and create better results than any anti-virus could ever hope to do for you. They won't ever get to 100% security, but then again, nothing will.

I think clamav is a good antivirus

At first: In most cases you don't need and don't want one.

I wanted to get one as I have several old (over two decades and more) Windows game CDs that I've bought long before switching to Linux. Back in the days it was actually a thing that sometimes malware slipped into professionally pressed CDs (especially on discs that came with PC game magazines or cheap game collection boxes).

For this case (Windows software check before attempting to run with wine) I can recommend ClamAV. It is open source and available on probably every distribution. But there is no need to attempt having it running all the time. I just run scans from the terminal whenever needed.

Unless you are in a cooperate environment or very careless with the stuff you download and commands you run you shouldn't need one!

The typical consumer Windows antivirus was designed to solve a different set of problems in a different environment and analysing files for signatures and behaviors against known threats was very valuable when so many people were running executables from unsafe sources intentionally or not. Even on Windows an antivirus has never been the best way to secure a machine. It was always the lowest common denominator solution that you put on everyone's machine because it was better than nothing.

Linux has been well served for a long time by the division or privileges between root and users and signed trusted distro sources. The linux desktop is trending towards containerized flatpak applications running in seperate namespaces with additonal protection via seccomp. Try and understand the protections Linux provides and how to best take advantage of them first and only reach for an antivirus if you still think it is needed.

Common sense. ClamAV exists, but I have no idea if it's worth it

Currently I don't like any of the common AV solutions, ClamAV is the best we have and has great signature based antivirus, with many excellent third party virus signatures (I even use it on windows). however ClamAV has no heuristic based capabilities which means it's lacking quite a bit in that regard.

I really wish we had a decent hurestics based AV solution oriented to consumers but afaik none really exist that are any good.

If you’re looking for personal antivirus, you probably don’t need one. ClamAV is an option, but it is aimed at scanning emails rather than anything else. If you’re looking to protect your company or a network of computers, then Wazuh is a great choice.

ClamAV goated

Use common sense and dont install random shady shit from the internet.

Best antivrius in the world

Yes, no antivirus. You don't need it. There are no viruses. Plus, the way Linux is setup it's not easy for a virus to do alot of damage.

Common Sense Antivirus(tm) is breddy gucci.

I've been running Linux for 20 years. Not once have I been in a situation that required an antivirus. The one time I've had a security breach it was not a virus but user error that left a door open. And even then, it was just ransomware, not a virus.

Virustotal is great to scan anything you download that does not contain sensitive information, and ClamAV + TK will work locally to scan anything that contains sensitive information (e.g. documents sent by others) or things too big for Virustotal.

Like others are saying, there's less of a need for antivirus on Linux since there's less easy entry points (e.g package manager over downloading an installer) and less (but far from 0) malware made for Linux. But we all probably download app images or get documents related to job searches at some point and I personally prefer to scan almost file that I get from a remote computer.
