That happens more with paid antivirus than with free.
Some paid antivirus are actual malware.
McAffee and Norton come to mind, but I’m sure there’s more
I love how the personal data is depicted as a physical object that isn’t there any more.
And yet when people try and defend piracy, they say that because it’s not a physical object it isn’t stealing
It could be ransomware.
You’re right, it’s not stealing. It’s spying, or stalking, and I’d go to jail for doing it.

Does anyone have any insight on how Malwarebytes is on this front?
Malwarebytes is pretty basic and probably does but I still have it.
I also use Spybot Search and Destroy as well as SUPERAnti spyware.
Idk I always felt they helped keep my basic PC used only for gaming and general web browsing running smooth.
I’d love to hear more of alternatives and stuff
All anti virus software actually, not just free ones. The paid ones are probably even worse.
except ClamAV
yea, because they have all payment info. for a while we were able to crack eset.
but now i have to pay 15 bucks a year for a key on kinguin
McAfee basically is a virus. Pops up like hell’s popping corn and is hard to get rid of
They do that to simulate usefulness. Like “that was a close one, without me you’d be increased by now” and “hey look at me now hard I’m at work”
Malwarebytes is like that too. They also bombard with ads to pay for their premium services and shit.
what is your source on this? “trust me bro”?
My source is that’s exactly what I experienced when I used to have Malwarebytes on my PC.
you “experienced” Malwarebytes stealing your personal data? and doing what with it exactly? and how did you detect and verify this happening?
It actually bothers me that I have to spend Enterprise levels of money to get access to any type of Linux endpoint security a la Bitdefender Gravityzone.
I get it, “they don’t make viruses for linux” or some nonsense. When a massive number of corporate servers run Linux, I think it’s fair to say that’s a target surface for people to develop attacks that can include viruses. I’m just over this idea that we’re safe by default or something. You’re not really safe unless you make your own personal computer use a giant pain in the ass of security steps just to access basics, anyway.
Anywhodles, anyone got the deets on some actual quality Linux virus/worm/malware protection beyond stuff like security hardening, key authorization, firewalls, dns blackholing for ads, and everything else I already have and set up beyond “virus protection.” My servers may not be important, but they’re still servers I’d rather not go through the pain of rebuilding.
Honestly…as far as I’m concerned, for linux servers (any servers, but linux servers especially), there isn’t much value in a traditional AV client that runs on the server itself.
Viruses and malware come from people downloading crap and going to shady websites. People shouldn’t do that on servers, and it should be blocked anyway by web filters.
Honestly if a linux server even has a web browser and xorg/wayland installed, you already fucked up. I’d allow lynx in niche circumstances.
There should be security layers long before anybody gets to the linux server…namely IPS’s and firewalls.
Most enterprise firewalls have a way to block known-baddies on their first SYN. There are probably several community-driven blocklists that can be imported to other firewalls, or even directly into the host-based firewall (which should also be running, along with SELinux or AppArmor or whatever)
The real threats with linux servers are:
- lateral spread
- compromised accounts, poor privileged account management, or insider threat
- exploited vulnerability, which is most likely the entrypoint.
Keep SELinux/AppArmor up, manage permissions properly, have webfilters, IPS, L4 Firewall, WAF (if appropriate) in-line, and have an automated patching strategy. AV software does none of this (and would probably ask you to disable SELinux as step 1 in troubleshooting…)
Oh, yeah, and run applications in unprivileged containers wherever possible.
IOW, the solution is good cyber hygiene. At the server admin level, the biggest concern should be managing RBAC and patches.
I only wish I had a spare device with specs good enough to properly run Snort. Having an IPS isn’t always an option, sadly, for people doing this at home.
I was fortunate to build a homelab right before the market went crazy. I invested heavily into 7th/8th gen intel and DDR4.
I’m actually about to part out my lab – I just sidegraded my CPU from 5700G to 5600X3D…so I’m gonna put the 5700G to the task of ‘all my eggs in one basket’.
But my current lab consists of:
- Lenovo M710s for OPNsense
- 2x Lenovo M710s and 1x Ryzen 5825U uSFF in a kubernetes cluster (used to be 3x M710s, but I put the 5825U in there for the vega transcoding)
- A NAS (i7-6700, all the DDR3 I could fit on the board, LSI controller, some disks, etc)
I’m hoping to put all that into the 5700G, and squeeze in my old RX570 for a VM responsible for Jellyfin, but I’ll have it boot to retroarch and set up sunshine on it, so it’ll basically just be a persistent gaming VM like an always-on console. That way I can play practically any console, on any device in my house. Or PC game somewhat decently from my laptops.
It’s in the fun stages now of homelabbing…gear is fucking expensive, what can I do with what I’ve already got (especially w/r/t gpus, memory, and storage).
I’ve got some M910q’s I gotta find a use for. I’m thinking HTPC (as part of de-googling my life and getting rid of my Google TV’s), but I need to find a good 10-foot, controller/remote driven interface that isn’t Kodi. It looks like Plasma Bigscreen is out now, I’ll need to check that out.
Anywhodles
You made me smile
Remember, kids: don’t do security by obscurity
Yeah for sure. AI has made that even more redundant now by removing the effort barriers also.
I know a corporation that runs on that premise, and it worked great up until they added modern frontends as “translator” to modernize the system.
First of all, username checks out.
Second, the thing about viruses (as opposed to other types of exploits) is that the user has to run them, and Linux doesn’t make downloaded files executable by default the way Windows does. Nor are Linux users conditioned to download programs from random sketchy sources the way Windows users do.

I think about this every time install instructions for something are “run this terminal command to add our repo to your sources”. Would probably be pretty easy to get an auto-updating attack path for the unsuspecting. The first drop doesn’t even need to be malicious, just ship the virus as an update.
Yeah, if you’re doing some sort of
curl | shnonsense you’d better trust whoever is supplying that script implicitly. On the bright side, I’ve only ever seen that on the first-party website of the project being installed, so it could be worse.I think about this every time install instructions for something are “run this terminal command to add our repo to your sources”.
Or when there’s an installation option that’s just piping curl/wget into bash, like
curl -sSL https://install.pi-hole.net/ | bashIt’s super convenient! But risky. Even if the fetched script is legit, the command is still one typo’d URL away from fetching and executing something entirely different (imagine squatters sitting on install.pi-hole.com instead of .net and serving a malicious script)
I appreciated that pi-hole was (and still is) transparent about the drawbacks of this installation method when I installed it years ago.
I think the biggest risk now is supply chain poisoning, where a system update or package installation runs executable code alongside it that can be malicious, as most supply chains for Linux distros don’t have automatic security checks in place but rather rely on the security of the identity of the package maintainer. If their setup gets compromised that’s the bigger risk rather than the traditional “virus” like you said
I don’t think people are saying there’s literally no viruses for Linux, just that because Linux desktop use is so low, malware developers l developers focus on Windows because that’s what most end users will be trying to run their software on.
It’s not a secret that lots of Enterprise systems run Linux. Almost all switching and routing operating systems that run the entire internet are Linux based. But there isn’t a person using those. They get configured and then run without user interaction. So their attack surface is different.
That’s what people mean when they say there’s no real malware for Linux.
Most “virus” infections this day are just programs that look legit and trick people into installing them. You’re not going to get a Linux server that way.
Also people using Linux are some kind of brain and understanding of computers. Not necessarily the case on windows.
No, the ones who say this kind of stuff are literally believing that there is no malware on Linux, and there is precedence for it.
Something something history is doomed to repeat itself.
I think the day there’s a widespread apt or pacman hidden malware ala npm will be a watershed moment for the Linux community. A lot of people don’t even have clamav installed
the day there’s a widespread apt or pacman hidden malware
You mean like all the recent exploits on the AUR? It’s already happening. Digital hygiene is a responsibility that many don’t take seriously.
Well, time to switch to BSD /s
I’m worried even some random package like
fastfetchgetting compromised. I never installed that, it came with CachyOS, and it’s an “official package”. Does anyone actually check all 70+ packages that update per week? I dunno, it gives me the same uneasy feeling when I first was introduced to NPMWell, there’s a difference between that and NPM, which is that there are some manual steps involved. There’s no standard way to “push an update to every distribution in existence”, you just put out a sign somewhere saying “hey, new release” then everyone has to look at it and package it in whichever way they feel appropriate, oftentimes to a “testing” space first before the “regular” one. Some random Gentoo user who rebuilt just same day would notice way before Alpine stable people, for example.
Even Jia Tan wasn’t too successful, their backdoor only functioned when in a small set of distributions (Debian…) and yet got noticed almost right away.
The only major malware that isn’t for the big 4 right now are:
- ones that are preinstalled in IoT and “smart” devices
- targeting said devices with remote holes (ironically sometimes made available by the preinstalled malware)
Yea, I’ve got the same issue, i couldnt really find anything either so ive just been using portmaster and hopping that’ll catch the virus if i ever get one.
A good anti-virus company would soon go out of businesses if they did not secretly create viruses and deploy them out to the world so they can come to the rescue. Not much different than planned obsolescence of washing machines and such.
If only there was a community driven, open source anti virus, that is easy to use, and available for Windows…
Is this sarcastic or is there one?
ClamAV. Not the shiniest one around and I’ve never used it on windows, but it does exist and filters malware on tons of email servers around the world (among other things).
Curious… have you ever had it prevent infections on your machine?
I just started using it, being quite new to running a Linux desktop. With the AUR attacks recently I thought I’d intentionally download an infected archive just to see if ClamAV would detect an infected download or at least a directory scan… it did not. I waited several days, updated it and scanned again, but still no luck.
Maybe I’m being unreasonable but coming from Windows and it’s Defender utility, it seems to be updated much more frequently. I know a person running Windows a person is more likely to be a target than a Linux user, but still it seems like up-to-date AV protection is lacking on Linux and will likely be a bigger problem as Linux desktop popularity grows.
It blocks malware every now and then on my email server and I’ve seen it clear files on samba-servers with windows clients and prevented infections from spreading in the network. So, it’s not useless, but it’s not on the same level than commercial competition either.
I think a big part of the solution of this entire problem is some form of sandboxing. That way, if one of your sandboxes gets a virus, it won’t have access to information that is outside of that sandbox, and you can delete the virus by deleting the sandbox. At least in Linux, when you install something as a flatpak, it’s automatically in a sandbox. Another example is that some game launchers can automatically launch games in their own sandbox.
Of course, then you have the issue that certain programs have access to tons of personal data and also get used all over the place, like web browsers. Even if you install those in sandboxes, I’m not sure how you can protect yourself, apart from really locking it down and then vigilantly cleaning the directories that they can see. But that’s a lot of extra work. A good solution would be more automatic.
Unfortunately Linux had quite a few kernel level local privilege escalation issues recently. The sandboxes use the same kernel as the host. However, still better to have a sandbox.
Also webbrowsers a use sandboxing for ages and split privileges between multiple processes but can still have critical security issues.
Even full blown VMs sometimes have issues that allow escape to the hypervisor.
I still really like sandboxing and I’m not a huge fan of antivirus solutions, just saying it’s not a magic bullet.
I did only say that I thought sandboxing was “a big part of the solution.”
At least in Linux, when you install something as a flatpak, it’s automatically in a sandbox. Another example is that some game launchers can automatically launch games in their own sandbox.
Even then, however, often you have to give those flatpaks access to more system resources to work, which reduces the effectiveness of the sandbox and give viruses other paths to escape from. It’s not a lot of flatpaks I’ve had to do this with, but for the ones I have, it’s been a pain and a little bit frustrating that I have to open access to certain system/user files for it to work.
Also, I’ve just had trouble with certain flatpaks and their packaging for a long time now, but I’ve had various issues that are frustrating with both flatpaks and appimages that I simply don’t have when installing from the apt repository. Sandboxing is useful in certain cases for sure, but maybe not for everything sadly.
So, the way I see it, there are three layers of managing security for sandboxes. There is the developer. There is the distribution system. And then, there is the user.
Flathub gives warnings at the top of each app’s page. Ideally, they’d block publishing of apps that need a dangerous amount of permission, rather than just warning the user, but I understand why they don’t. I think they need like a flatpak secure mode that removes dangerous settings when installing a flatpak, and then they add to the top of their pages which apps don’t work with their safe installs.
I think then, that the future of flatpak security could evolve to alleviate the problems you mentioned. For one, as flatpak adoption increases, developers will end up at least looking at their flathub pages and have a desire to reduce those warnings.
Because right now, too much burden is placed on the user. I’m hoping that the technology will evolve to put all of the burden on the developer and the distribution system.
Something easy you can do for web browsers is just have at least two installed: one that you use for personal info and trustworthy sites, and the other that you use for unknown/sketchy sites.
Free is usually better than paid. With paid you have a profit motive from the onset.
The one and only time this is wrong.
At least they can make money spending way too long making an anti-virus.
Free is unsustainable, so most likely they are robbing you, or trying to sell more of the antivirus.
Most consumer-oriented paid antivirus programs were and are pretty much their own malware.
