Most modern antivirus software is a virus in and of itself.
We always say that McAfee uses all the system resources so the virus doesn’t have anything to work with.
At home I have MS defender turned on by default on my windows machine. I was copying the contents of one nvme to another the other day and noticed I was only getting 60MiB/sec. I looked at task manager, realized why, turned off proactive scanning of files, and watched it jump to over 2GiB/sec. Really nailed that point home.
I don't use antivirus on Windows, let alone Linux. Just be mindful of what you're downloading and you'll be fine.
Windows has done of the best antivirus built-in
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.
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.
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.
Antivirus is a technical attempt at solving a stupid user problem. It does not actually prevent any problems and causes many of its own.
Frankly, some phishing attempts, especially at work, are pretty good in my opinion.
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.
I don't, but that's because of how I have things setup around the network. While most people here say it's because they don't need it, I am in a position that I need SOMETHING simply because others in the household could bring in malware and rather than trust them to make smart decisions, I proactively monitor all network activity for anything unusual. That being said, I have clamAv installed and run a weekly scan, but my real "antivirus solutions" are as follows: A syslog server that's connected to grafana/MySQL and alerts me based on very specific criteria. Along this, I've got my network firewall configured to block all "untrustworthy countries" in and out 100%, as well as use an IDS/IPS (also connected to syslog for alerts). Lastly, an internal DNS which grabs from like 20 sources that include some reliable lists with malware domains and such, and a custom list of my own that I add to as useful security news feeds hit my RSS feed with urls in their blog posts.
Actually got a list of other things going on in the network to make it even more secure, but just wanted to list the main things that'll give you a step up in the anti-malware front.
None of this is buletproof without proper care for how you use the Internet, though.
You get the idea. My message got way too long and turned into a rant lol.
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
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.
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'm not sure if you recommended syncthing a backup tool, because it isn't one. Just making sure that there's no confusion...
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
Personally I don't use one on any platform because the antivirus companies tend to... Create problems in order to solve them. If you're going to use one on Linux, ClamAV is probably the play. However, far better for your security is to pick a distro that publishes security patches quickly, like Debian or Arch Linux, and then to update your system frequently
No, it's Linux.
Linux still can get viruses. Just not as likely
The pattern of using managed repositories instead of downloading random shit off the internet prevents a lot of it outright.
Just have to remember which repos are “managed” and which are not. Installing stuff from PyPi or NPM might actually require you to read through quite a lot of code before installing. I don’t think most people are that diligent.
Yup, and much of stuff is just common apps. A browser based exploit may not care which OS you're running Firefox/Chrome under (or Edge, I suppose if you're one of the dozen running that in Linux). The log4j vulnerability was first seen in Minecraft hosts and clients, and that equally affects those running on Linux. Steam has also had vulnerabilities in the past, as have various document editors.
That said, I really can't say there's any consumer-level antivirus that I'd trust to be effective on my desktop (especially without impacting performance) even on Windows, let alone Linux. If you really know what your box is doing and it doesn't change much you might consider SELinux rules etc, but those are a significant amount of work even for servers (which tend to behave more predictably).
Not using software from untrustworthy sources or visiting sketchy sites, plus some monitoring of your network traffic may be a more effective solution.
This (Also is there a service that audits code's maliciousness for me? I sometimes use some unfamous stuffs from github for gaming, customizing etc. As long as I don't give them a root permission I should be ok?)
There are tools that do this but it's mostly for known issues or vulnerabilities (i.e. bad practice in coding or done after the fact). Some stuff runs code on at sandbox looking for sketchy behavior, but hackers may work around that by having malware that only activates in CD l specific circumstances or times.
There can also be "privilege escalation" exploits which can allow a rogue process to obtain root/admin, and even without the process would have full access to whatever the user does in terms of network/device/hardware/process access (or sudo, as applicable).
Not being able to run as root doesn't help all that much if the process is able to access sensitive saved data, files and/or the internet
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 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.
That is always a possibility. The only av currently existing that is free is clamav - there are multiple gui frontends for it since it's really meant for servers and stuff - I've mainly seen people use it to scan files before you send it to a windows user tho so not much use unless you need to do that
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.
The best antivirus is yourself
whacks you with a rolled up newspaper NO. BAD.
this is only true for users who understand good habits and bad habits, people who understand how their computer is vulnerable and how they are vulnerable, people that know what's supposed to be on their computer and what it does and why. It's not true for someone who doesn't know what they don't know, or who is only just starting to understand the scope of malware and phishing and other malicious activities.
Exactly. I can't know what I don't know.
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.
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.
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.
