I've been learning about Linux while waiting for a new computer and malware protection is one of my biggest concerns. Does Linux have antivirus tools comparable to those on Windows? Do most distributions include a firewall, or would I need to configure one myself? Can malicious websites or browser-based attacks affect a Linux system, and does the distribution I choose make much difference? I'm not expecting one person to answer everything, so general advice or reliable resources about staying safe on Linux would be appreciated.

Most distributions already include firewall support, and you can configure rules if you actually need them. Antivirus software is available, including tools such as ClamAV and some commercial scanners, but desktop users generally don’t treat it as essential protection. If you exchange files with Windows computers, run services exposed to the internet, or download questionable software, scanning can be more useful. The specific distribution matters less than keeping it supported and up to date.
Linux malware definitely exists, since malware is still software that can run on a compatible system. However, it usually needs an exploit or the user to download and execute something dangerous. Most desktop Linux users are fine with regular updates, avoiding untrusted downloads, and not running commands they don’t understand as administrator. Linux is less frequently targeted than Windows, but it isn’t magically immune.
You generally don’t need to design a complicated firewall or install antivirus immediately. Start with a mainstream, supported distribution, enable automatic security updates, use a normal user account for everyday work, and install software from trusted repositories. Extra security tools should address a specific need rather than being added just for reassurance.
Browser-based malware can affect Linux if the browser or a website exploits a vulnerability, but simply visiting ordinary websites doesn’t normally give them unrestricted access to the system. The bigger risks are malicious extensions, fake software updates, pirated downloads, and commands copied from random guides. Use a supported browser, install updates promptly, keep extensions to a minimum, and be cautious before granting programs elevated privileges.
That helps. I’m also not always using official streaming services, so I’ll be more careful about downloads and may look into scanning tools.
