Hello! Sorry maybe for this beginners-question: do I need dedicated anti-virus / anti-malware software for my Linux System?
I’m not using my laptop for anything shady: no filesharing, no pirating, etc. Just the usual boring bit of work or streaming or surfing the web. Do I need dedicated safety measures? Like ClamAV for example? I read a bit about it but there where mixed messages, where people said it’s not needed.
I’m running Linux Mint and Cinnamon on a laptop since a few months and couldn’t be happier with an operating system. Everything works fine and until now I had no trouble at all (besides this little annoying bug, where my touchpad gets randomly set to “deactivated”, but this really is a minor issue and maybe just a “stupid user”-Problem).
Before I suffered through decades of windows. But no more!
My understanding is that no amount of anti-virus software replaces common sense. As long as you’re not downloading sketchy programs and giving them permission to run, you’re pretty well set.
Some people might tell you that there’s no viruses on Linux, but that isn’t exactly true. Linux has something like 2% of the desktop market, which makes it less attractive to develop malware for - but 2% of a few billion computers is still millions of potential targets. Not to mention that Linux dominates the server market, and arguably that’s where malware is more valuable. To think that there’s no malware targeting Linux is naive.
Many anti-virus suites are effectively malware though. If you decide you do need AV software make sure to do your research before installing any.
Anyway, long story, I don’t personally use an anti-virus, and for your stated uses I’m not sure I’d recommend one.
If you’re mostly using it as a web browser then I would definitely recommend a solid ad blocker. UBlock Origin is free, highly esteemed, and can be installed as an extension to whatever browser you’re currently using.
Thanks for your answer! Ublock Origin is a given in all my browsers. Web is not usable any more without.
I read recently that ~90% lots of malware comes through ads, so it’s a really great security help as well.
No.
Could they shorten it up a little? I’m not big on these wordy detailed answers. ;)
Not really. Contrary to what people say, there is practically no malware targeting desktop machines and the risk is close to zero. There have been a few select pieces of malware during Linux’ history. But as far as I remember nothing to worry about for desktop users. You need to worry about security if you run a server. And ClamAV and such are mainly for scanning for Windows viruses, so noone else in the network gets infected by files they download from your server.
Do backups, though. Loosing all your files is as easy as running ‘rm -rf *’ in the terminal.
And as anecdotal evidence: I’ve been running Linux for like 20 years and I know lots of people who do. Practically no one I know uses an antivirus. And I know 0 people who got their desktops infected. We had our servers targeted though and the website defaced because we didn’t update the webserver for nearly two years. That definitely happens.
Yeah and as other people pointed out: use software from the package repository of your Linux distribution. That’s the nice thing about Linux and a popular Distro, that most popular software is packaged and ready to install with one command/click. Lately some users have adopted the habit of installing lots of software from random sources. I avoid that unless it’s absolutely necessary.
You can install an antivirus, but you really don’t need to. Malware for Linux is rare, and malware that targets desktop Linux users is extremely rare (to the point that it’s a newsworthy story every time it does appear). Most distros have ClamAV and the frontend ClamTk in their repos, but it’s primarily used to scan servers for Windows malware before it reaches its intended target. Some Windows malware can still be harmful if run with Wine/Proton, but unless you’re downloading and running a lot of Windows software from unofficial sources (which you shouldn’t have any reason to) that won’t be a risk.
A lot of people here are “use Linux!” Well as Linux’s desktop share goes up, so does it being a target for attacks. The more people you have, the less that are going to configure it correctly (that’s just a fact, and not everyone will be their parents tech support) so it’s just a matter of time.
