Why aren't there any open-source antiviruses? There is ClamAV, which is barely used, and isn't that good to begin with.

Is it because the attackers can easily bypass the security of the code is in the open? Or is it because the market is already oversaturated?

Is there even a reason to try and make an open-source antivirus, that can compete with big players like Avira, Kaspersky, and others?

@NickKaramoff I imagine the on-going work to write the definitions and behavioural analyses, following OS changes and the delicate nature of hooking into I/O drivers makes it such a huge ongoing effort.

Do you have any sources as to why ClamAV isn't that good?

@NickKaramoff I imagine it's because so many FOSS folks consider themselves too smart to need an antivirus. :ms_stick_out_tongue:
But jokes aside, not sure. It'd be wonderful if we had more of them.

@NickKaramoff Obscurity isn't security. Any AV that rests on the assumption that its code is somehow secure by being closed-source is one worth avoiding. Granted, I doubt any of them actually do that.

There is always a reason to make an open-source competitor to anything closed-source, as a matter of principle that we should eliminate closed-source software. See above.

I think the real point is that virus definition updates take a lot of man-hours to be useful, ie. timely.

@NickKaramoff interesting thought and I want to know the answer too.

@NickKaramoff I'm using Linux Mint and I don't see any point of using an antivirus. When I was a true Windows user from maybe 2017 and back, I was a Kaspersky fan and user for over 10 years.

But Kaspersky aren't nice privacy-wise. They got banned in the US for an incident in 2014.[1] They also installs their own SSL certificate and makes it trusted by default.[2]

I love/adore Kaspersky even today, but there's a limit!
