Yes.

It has an antivirus in the repositories anyway.

I've never run antivirus on Linux. I've been using various distributions
for over five years - currently have five home systems on the net
14/7/365 via broadband - I've never had an infestation.

Have you look at what the AV vendors supply for Linux.
Reason there is not much AV protection for /Linux/ malware is because
it is none running around. Any exploits found are fixed pretty fast
and delivered next day. Now waiting for Second Tuesday of the Month.

Funny question there. You kinda mixed your apple and orange comparison.
Last port scan of "out of the box install" I made of ubuntu showed all
ports closed.

That does "prevent third parties accessing data" from the Internet.

As soon as you install/enable services/daemons, those ports will be
open to attack.
Before that point, you would want to enable the firewall.

As for accessing your data, black hats have moved from attacking your
system from the Internet to attacking your system from your
applications. The main attack is serving malware via cracked Ad
servers and cross scripting via java.

If you were to keep up to date on all your applications as soon as
they have updates, run Firefox with NoScript Add On and privoxy
installed with lots of blocked ads in user.actions, you would be ahead
of any AV Software sold for /Linux Malware/.

I do not wait for Third Party Apps like Firefox to show up in package
selection. I download/install from the Vendor as soon as I know of an
update. Example, I am running Firefox 2.0.0.13.

For intrusion detection you can install something like
aide, ossec-hids, samhain, tripwire, snare,...

I happen to run Mandriav Linux which installs with the firewall
enabled and have privoxy and aide as additional package selections.

Don't worry overly about a virus - do worry about using WEP. Do not use
WEP if you have secure data. WEP is NOT secure and if your data goes over
that wire people can get at it. Use WPA.

Do not listen to anyone who says otherwise.

You are confusing access with virus infection.

Your Linux install will be as accessible as you make it. This is a
function of your networking configuration and file sharing settings. The
defaults are darn tight.

But, no matter how accessible your data is, the machine is essentially
immune to malware infection in the conventional sense.

I've run Linux distributions of one sort or another for 10/11 years & never used
an AV. AV applications are only any use if you have windoze machines in your
network, to stop them getting infected.

No you don't. Switched from Windows 3 years ago, never had any

You do not need an antivirus if you use only Linux, but if, for
example, you use your linux copmputer to relay mail for windows
computers, you may want an antivirus such as clamav.

The only thing I would concerned with is a firewall. Use firestarter it is simple.

How do you know?

Your statement distills down to "can't have happened because I
never bothered to look".

So you're saying no Linux viruses exist?

Did you know the very first virus ever was a Unix critter? And htat
it's still found in the wild occasionally today?

Didn't think so.....

My av software sorts out all manner of "cross platform" nasties
like html tricks and phishing scams.

Are you saying that's of no use to anyone?

Because a lot of knowledgeable people are every day looking for that
first Linux virus that'll survive in the wild.
I'm sure Microsoft will have a big announcement made when it happens

Until then the average Linux user only has to worry about phishing scams
and the likes but they're typically caused by gullible computer users,
not malware.

A different matter is when you're running services that are open to the
net like an Apache web server, especially a root kit could cause serious
problems.
But again, the usual AV software wouldn't know about it.

No self propagating Linux viruses exist, they cannot replicate so in
essence they are at worst malware.

Basically these few programs are all concepts that don't survive outside

I only have one of my email addresses which gets a little spam from time to
time, but spamassassin removes any phishing & HTML posts along with UCE.

Is this some wintard whining about the Morris Worm, fercryinoutloud?

http://world.std.com/~franl/worm.html

You'd think wintrolls could find something newer than 20 YEARS. You really
"care" about net sanitation--start with M$ botnet spam TODAY, 'kay? And it
doesn't include FOSS cleaning up AFTER deliberate M$ net sewage spews.

Again: M$ better take care of the net, or the net will take care of M$.

Well said

As if there has not been any progress in the past 20 years!

This rather unique occurrence happened well before Microsoft run
computers were habitually connected to a network and was a lesson for
all system admins and software developers.

Well not quite all, when Microsoft finally found the net they seemed to
have thought common sense re. network security did not apply to them and
now we all suffer the consequences.

(I just wonder why it sounded you directed this as an accusation at me?)
