I'm just tired. On the last post about having Linux at our work, many people that seems to be an IT worker said there have been several issues with Linux that was not easy to manipulate or control like they do with Windows, but I think they just are lazy to find out ways to provide this support. Because Google forces all their workers to use Linux, and they have pretty much control on their OS as any other Windows system.
Linux is a valid system that can be used for work, just as many other companies do.
So my point is, the excuse of "Linux is not ready for workplaces" could be just a lack of knowledge of the IT team and/or a lack of intention to provide to developers the right tools to work.
The original post made the claim, I merely stated fact that Linux can be vulnerable to viruses like any other OS.
Want a straight forward answer?

A virus is a specific type of malware but for the general public is broadly synonymous with malware. Ask the average user, and the commenter in the OP screenshot, what the difference is without looking it up and they can’t tell you.
A virus doesn’t need to be spread broadly for it to be concerning, impactful or dangerous. Often these attacks are very carefully targeted at the victims.
A vulnerability is generally exploited by a virus to inject code by either modifying memory or files the target program relies on. One such vulnerability was
https://arstechnica.com/information-technology/2022/03/linux-has-been-bitten-by-its-most-high-severity-vulnerability-in-years/
With this vulnerability it was possible to modify any file on a Linux device, meaning viruses would be simple to implement and deploy. Many android devices are still vulnerable.
To think that all possible vulnerabilities have been fixed, or are known to linux developers, would be extremely naive.
Furthermore a virus is often targeting a specific application and while OS level controls restrict the avenues of attack it doesn’t prevent flaws being introduced by developers.
You’ve already been given a list of viruses for Linux, if you’re genuinely so concerned with defining them by impact you can look them up. You have the information needed to do this yourself, and it is not my responsibility to educate you, though I do seek to counter misinformation where possible.
Well, the first article pretty much says what I'm saying. In theory there can be viruses. In the real world they have pretty much no effect. They are more a curiosity than something that really exists and has had consequences. It even says you're installing antivirus because of the windows clients, not because there were linux viruses.
The second article also is about a security vulnerability and talking about potential consequences. Not a virus that uses this as means to infect people. Not actual consequences.
We're going in circles. I'm sorry.
And a virus and a vulnerability in some software (or kernel) that can you get hacked are two entirely different things:
So while talking about cybersecurity. Why would I lump all that together and strip the words of their meaning? And in this case on top: One thing is something that actually happened. The other things are just words about something hypethetical. I'm aware you have to protect against potential threats. Nonetheless both things are something different.
Regarding your advice: Yes. I've looked it up. I found no viruses that had any significant real-world impact. Hence me insisting on it. I said in my first comment I want to see impact. Not an academic study. Because context matters. We're talking about someone advertising Linux to an undetermined group of people. These people are concerned with implications for them. If they need to worry. Not if in theory anything can happen. That doesn't help you choose between two options. And we're talking about 'simple truths'. They're kinda always false. But people want to hear them. They want it condensed into one sentence. Because they own a company that manufactures car tires and they don't want to get a 20 minute lecture about computer attack vectors. They want to hear if they need to worry about their Linux server. Is it safe or not, do I need to pay someone to install Sophos? And be done with it.
You're twisting my words so they lose meaning. And change the context. And then posting articles about something related but not the thing.
So you found viruses, which debunks the claim in the OP, yet you remain skeptical they exist.
We're done here.
Please read my first few comments. I've talked about it and that's not what I said. I have found no viruses conforming to what I've clarified in my very first comment. I've also explained why it's important to differentiate. I have found things alike. But never the thing. If you twist my words enough and change the context, it would almost seem like I'm contradicting myself, yes. But you're the one twisting things around until you're right.
And why are you just now talking about that? Nearly every single comment of me starts right with a sentence that clarifies what I mean?
Frankly I don't care about whatever "metrics" you have made up to justify your ignorance.
Actually I have a better idea, please contact Linus Torvalds on Mastodon with your opinion that there aren't any viruses on Linux.
I will happily eat some popcorn while reading your eviceration.
For the record: I'm not the one changing the meaning of the word. I use it like in the definition. You're the one extending the meaning arbitrarily.
I think I'll just wait and see if some expert comes along and gives me my single example. If that doesn't happen I'm going to stick to my opinion: They exist in theory, but not in practice. And vulnerabilities and rootkits exist, but a vulnerability isn't automatically called a virus because those are different things.

To end with some more friendly words: I'm pretty sure some people are confusing the words 'malware' and 'virus'. Malware is the umbrella term. I've already admitted there is malware. For example the Mirai worm i think had affected hundreds of thousands of IoT devices (speaking of fire and forget embedded linux). And I've seen wordpress plugins with vulnerabilities and actual rootkits on webservers myself, as I told earlier. But I've also said in this context the distinction matters.
