[kwlug-disc] so ... what's your opinion on linux anti-virus software?

Apologies to the list, for those uninterested.
This thread is akin to Windows vs. Mac. There is no answer, there is
no resolution. But a lot of air gets thrown about anyways.
Not a bad thing, but can be wearisome for those not interested.
Zeke's vs. presentation.
Apologies to Bob for his hijacked thread.

Agreed. And well presented IMO.

Bear in mind, my perspective here is, essentially, 'getting Linux to
My point is that what should happen, from an enthusiasts point of
view, and what does happen, or we would like to happen (_everyone_ be
happy and productive Linux users, producing good stuff all day long,
with secure and malware-proof systems), aren't the same. What we would
like to happen is everyone get that new toy and get on with their day.
Of those, very few will see 'getting on with their day' as playing
with the OS. Or the window manager.
People in general don't want to learn. Or to have that learning bound
up in intuitive doing. I will not take a course or tutorial in using
my toaster, I will plug it in and stick a piece of bread in. Full
stop. Computers are not an end in themselves.

He doesn't care. It's not in his worldview.

But they don't. I've heard it said that people can't be allowed to
work that way. But they do. It is up to the installation to prevent
them from working that way.
I expect FutureShop, GeekSquad or whatever, makes some bucks fixing
users systems that have slowed to zero due to viruses. Most likely
due to expired Symantec licenses.
How many people keep their tires inflated properly. Especially in
winter. (Temperature changes having a significant impact on inflation
level.) When's the last time you checked the pressure in your spare?
THIS IS YOUR LIFE PEOPLE! But we don't do it.

Most will never talk to anyone. Certainly not them geeks from the LUG
- they talk so fast and I don't understand them and I don't really
care. (If I run at home what I do at work, I won't have to learn
anything. Which goes back to Linux being the standard on office desktops.)

No, in this case, their bank is Microsoft. Who's these Debian / CentOS

When they call this bank ... and your credit card number is ... click.
They won't call anyone. It works, or it doesn't.

Back to thread start. Basic point is, out of the box, 'virus'
protection should be in place. Full time, on the fly.
Yes, they can write and e-mail that letter. But in the process they
should not be able to expose themselves, or others, to malware.
(Part of the insidiousness of providers, these days, is coming with
Symantec AntiVirus. Oops, what do you mean it's only good for 1 year!
It has created a culture of 'coming with the OS.') Let alone Windows
coming with solitaire.

BUT YOU'RE NOT THERE. They go to FutureShop, buy a box, turn it on. We
WANT them to see Linux when they do so. MS Defender or whatever
they're calling it now, will be pre-set. Linux needs to do the same.
It needs to be safe out of the box.
(We won't go in to all the $$$ arguments why Linux isn't
pre-installed. Some day we'll get there. We've all seen in the last
few years some rays of hope. It will come. Not likely in my lifetime,
but it will come.)

Until those exposed to Windows XP (which is to say, a GUI with a start

But Windows is what they are exposed to first. Anything else is
different. I certainly don't like it, but I have to deal. e.g. As
discussed at Zeke's a few months back ... yet again, somehow, MS has
taking over the colleges and universities. <sigh>

To the users, there's little difference. They clicked here or there

True enough. But we're not there yet. And we have to get along in the
mean time. By 'anti-virus' I mean 'safe' here. Anti-virus is a
component of that. I shouldn't get harmed, I shouldn't be able to harm
others - it should just happen. I won't think about it.

That's just wrong. I'm the admin, they're on my network, I cannot
allow them to harm others. I cannot allow myself to be harmed by them.
I cannot allow them to infect me such that I may pass it on to others.
I have no control over what they do once I ship them the computer. So
I, as deployer, put some safeguards in. To them, 'it came that way.'
It's the OS.
The idiots are the ones in control. Or, as an admin, the idiots are
out there, they are allowed to connect (beyond my control). I as admin
have to quarantine them, accommodate them, work around them, and work
At home, bad things are out there. I cannot allow myself to be harmed
by others, or to harm them. For those others, the distribution is how
'it came that way.'

Because it shouldn't have gotten there in the first place. Out of the box.
To your point regarding complexity - yes, they will inherently get
some education, to the extent they are willing to absorb.
That education will be about how to use the app, not the OS, or

Paying is true of anything. Same can be said about car tuneups.

I don't think we disagree. But the education has to occur along the
way wherein people unconsciously absorb the material.
Not by having to spend multiple hours reading a book or screen and
learning about X before they can press 'Go.'
They put in a distro, and start playing. And learning about apps when
they do - not the OS. The OS needs to keep them safe, inherently. Or,
rather, the OS needs to reassure them that their perception that they
are safe is true.

Because it cost a thousand dollars.
People don't print pictures any more. That's why digital picture
frames are selling now. Dump camera contents to frame - inherent

Not what I said. They are safer. The OS needs to be safe, out of the
box. Anti-virus is one way, one of the few ways we have, of getting there.
And there are lots of nefarious people out there.

I think you're missing one of my points ... there's only so many hours
in a day. If they have a choice of spending time listening to that new
mp3 they downloaded, or reading up on security update procedures ...
They just don't. What they should and shouldn't do is irrelevant. What
they do do, is. Because of that, we have to protect ourselves, and
each other. Inherently.

You presume the security fix arrives before the security vulnerability
is exploited. (Which is sort of chicken and egg.) This isn't true,
even on Linux.
Your position assumes automatic security updates are turned on out of
the box. (Why is it so great a leap that anti-virus updates are also
turned on out of the box?)
