Linux
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I don't use antivirus on Windows, let alone Linux. Just be mindful of what you're downloading and you'll be fine.
Same here. Ever since I remember I don't have AV, just staying out of sketchy sites is enough. Most of malware is targeted at the least aware and cautious users.
I don't because no antivirus can protect you from yourself, I learned that the hard way while I was still using Windows many years ago.
I had antivirus and antimalware on Windows and I kept them updated and ran scans regularly, almost religiously, than I got a malware that antivirus couldn't detect (they take a while to be updated with new viruses/malware that constantly come out) and the only way to remove it was a blank new install following a specific procedure to clean it all.
That day I understood that no matter how attentive you are about your antivirus, you're never really protected until it's you who learns what to do and what not while accessing the web, so I did a bit of research about how to better configure my PC, how to better recognize phishing/scamming, using adblocker, don't download random software, stuff like that.
I basically learned "how to behave". I stopped using antivirus/antimalware on Windows and I didn't catch a virus since, then I switched to Linux and I still apply the same principles of "good behavior".
That's not to say I'm immune to viruses, I'm certainly not, but my mindset now is that if I ever catch a virus, it will be my fault for doing something I shouldn't have done, and I'll do my best to learn from it instead of relying on software to do that for me.
Antivirus is a technical attempt at solving a stupid user problem. It does not actually prevent any problems and causes many of its own.
- run only what you need
- get what you need only from trusted sources
- keep what you need up to date
- configure what you need conservatively
- admin/root account only for admin stuff. Don't use root as your general login.
Frankly, some phishing attempts, especially at work, are pretty good in my opinion.
- Virus scanners only detect a fraction of the harmful programmes.
- Virus scanners can often be tricked.
- Virus scanners often have security vulnerabilities themselves, which are usually quite serious, since such programmes embed themselves quite deeply in the operating system.
- Virus scanners cause many users to become careless because they rely too much on such tools.
Therefore, from my point of view, the disadvantages outweigh the advantages. Therefore, I do not have such a tool permanently installed, neither under Linux nor under Windows. However, every 6 months I scan my Windows installation with a USB-bootable virus scanner. No actually harmful programme has been found for years.
In my opinion, the following things are much more important than any security software.
- Install updates as soon as possible. Under Windows, you can use tools like Chocolatey for this.
- Only install software from trustworthy sources.
- Only install software that you really need.
- Only use root or administrator rights if you have to. For everything else, the rights of the user account are sufficient.
- Create backups regularly.
- Think before you act.
Especially the last point is a problem for many users. I can't tell you how many times I've witnessed someone receiving an alleged invoice from mobile provider A by email and opening it, even though they had a contract with provider B.
Run sandboxed software when possible and avoid doing unsafe things.
There is no useful AV for Linux desktops.
Haven't really felt the need to. On Linux ad blocking + common sense has worked out fine. When I was still using Windows I just relied on Windows Defender since around the Windows 8.1 days, but either way my time downloading .exe files from sketchy sites is long behind me.
No. Not needed for the most part if you aren't downloading dumb shit on the internet and keeping things up to date.
Nope.... Raw dawg that shit online.
I wonder how people get phished on IG and FB. Like the get account taken over and blackmailed over a social media account.... That shit baffles me. I'm pretty sure I know how they get phished but I'm just shocked it happens to smart people.
Smart people are not immune to moments of panic or laziness or cockiness. I don't know about you, but I don't always check email headers even tho that's the closest to best way to verify the identity of the sender. And if that link verifiably goes to a website I trust, and I was expecting them to reach out, and I just have to login to check my orders and... wait, why does the url have a "redir=" parameter? Oh fuck oh god oh fuck why does the login page say "amzaon.com" instead of "amazon.com" like in the email's link??? FUCK DAMMIT SHIT

This is definitely a situation where having a password manager with auto-filling is nice. When you save your login for amazon.com it ties it to the URL as well. So if you end up going to amzaon.com by any means and don't manage to catch it, your password manager won't fill in your details because it doesn't recognize the domain.
Of course, this won't stop you from say, using one of the "Login with Google/Apple/Amazon/etc" buttons on some dodgy website, and granting it access to your account (because you'd be redirected to google.com / apple.com / amazon.com) but it's at least an layer of "Wait, something isn't right here" when the auto-fill doesn't trigger.
Password managers are an absolute must-have in this day and age. That and MFA. And making as few accounts as humanly possible.
But, the more general concepts I'm trying to get at are that pobody's nerfect, you don't know what you don't know you don't know, and we're all just apes prone to lapses in judgment at innoportune times.
you don’t know what you don’t know you don’t know, and we’re all just apes prone to lapses in judgment at innoportune times.
Oh for sure, I 100% agree! My reply was more of an educational "Hey, in case you've run into this before, this is a great way to prevent it from occurring again" sort of deal. No one is born with all-encompassing knowledge of the world and everything/anything they could ever interact with, and subsequently no one should be faulted for running into something like phishing scams where they're designed to exploit someone's potential lack of knowledge or even as you mentioned, a lapse in judgment.
I normally am good about avoiding phishing scams but almost fell victim to one because a close trusted friend of mine had their account compromised, and sent a link to something on Steam that seemed in line with what they'd normally bring up with me - and it was exactly the fact that my password manager didn't prompt me to fill in my Steam login details on that fake page that prevented me from trying to login.
(Well that and I do have Steam Guard/MFA enabled, but still)
Exactly, my last full time gig was in cyber, soc analyst. Stay at home dad now screw all that stress.
Nope.
Why
I don't have wine installed.
Even then, the good old "Reinstall if things feel sluggish" always helps.
You dont need an antivirus if you don't run software from unknown sources, and you keep your machine up to date.
For the most part, if you do all that and you're still attacked, they would probably get past an antivirus, anyways. I've never had an antivirus catch anything after decades of running Windows.
A bit thing to note for people running home servers is to watch what they expose to the internet. Insecure software and insecure configurations are huge targets for botnets these days.
Anti-virus software is like a condom. If you don’t go sticking your computer in places it doesn’t belong you won’t really need one.
Today I learned what a dickhead my computer is
No. That would defeat the purpose of me installing Linux in (old) laptops. Windows feels sluggish enough with a sea of bad things wanting your minimum wage and have Windows Defender prevent it but not all of it, obviously.
I put all my attention to prevention and set strict rules on the router. It can be as simple as setting the DNS to stuff like dnsforge.de or DIY it with PiHole with hosts lists of your hearts content that update itself weekly, I do the latter. Nothing beats a cross platform solution that protects every device in the network, if you're after 100% performance. Of course you can still catch bad things, such as social engineering by email that happened over at Linus Tech Tips. You better stay vigilant no matter what solution you use and don't sleep on making backups, which can be as simple and automated when you use Syncthing for example.
I usually haven't, but I installed Clam about a month ago on my desktop, ran a full and complete scan, then left it running scheduled scans. Hasn't found anything, and I get a lot of software from outside of my package manager, and use wine for a lot of it, so I'd say my risk/exposure is higher than most.
I think it's fine to go without AV on a linux desktop, but I like the peace of mind. There will definitely be more things targeting linux sytems as/if more market share is acquired, but in terms of security it's more important that you harden the system than run an AV.
The anti virus industry boomed because of operating systems that were exceptionally vulnerable to attacks. Simply visiting a website could install software. The root cause of this problem isn't that a user didn't run third-party software. It's that the operating system was vulnerable.
After many years of neglect by operating system vendors, there really wasn't much of a choice in how to be responsible if you insisted on running a vulnerable operating system. Therefore, the industry boomed and it became status quo for users of these operating systems.
Or you could run an OS that regularly fixes vulnerabilities.
plus if your someone that makes malware are you really going to waste time making a linux version of your malware or just stick to the windows version.
This also assumes that Linux is vulnerable the same way that Windows is for the software, which is probably isn't.
No because I use QubesOS. If I got a virus it would be gone the next time I launched my browser.
This is great and most relevant answer from all comment on this topic imo! Viruses are evolve everyday, hacker always find a way to intercept computer that has same framework system.
QubesOS breaks that framework pattern and make their system more dynamic with VM-ing everything, so the impact of viruses are near-to-zero.
++ QubesOS also provide all security enhanced out of the box SO we can enhanced it more with other security tools rather than start from RAW system like majority Linux OS..
I have clamav installed, but only run it sporadically during attacks of paranoia. The only thing it's ever found was a Windows virus in an old email attachment among some files that had come from a Windows box.
The main thing you need to do to avoid viruses is avoid running untrusted code, which means, among other things, using paranoid browser settings. Linux tends to have fewer random holes where script execution environments ooze into places where they really shouldn't be, although even Windows isn't quite as bad about that as it was twenty-five years ago.
No. Because there is no need.
Antivirus just make people more negligent even in Windows.
No I don't use an antivirus because I don't download and run untrusted programs or scripts from the internet.
I do have some block lists on my firewall that block a lot of malware, phishing, and scammer sites though.
Properly educating the users is far more effective than any anti virus software.
I don't think there's a need. I keep my system patched and I only install from trusted sources. It might make sense in a corporate environment but for a single user machine I can't image ever needing it.
Nope, nothing. I use ESET Endpoint on Windows though.
No. I only use Android as my PC via AR glasses. Is there even any antivirus software for Android? Probably, but I don't care I guess. Never had a problem.
