    No. Again that falls under the super user permission system. Even if you mounted your Windows hard drive in Linux, it would be in /media/windows. /media is on the root directory and requires the use of sudo to write to that folder. Without super user access, nothing will "spread".

    The people who write viruses and worms aren't sympathetic to any group, that's the whole point.

    It's called crackers, not hackers!
    That is a major difference.
    Also, most people refer to kernel-writers (Linus Torvalds and Co.) as hackers.

    You can, however, mount your ext2 partitions in Windows very easily, using drivers that ignore the permissions and let you do anything to all the files there.

    Sorry bud, but someone who writes viruses is a hacker not just a cracker. There are several different types of hackers, the most prominent two would be white hat and black hat hackers.

    White hat hackers are the guys who mostly go around trying to find vulnerabilities in the systems of random businesses and tell them how to fix it. Lots of people make a living off this; they don't always do it for free.

    Black hat hackers are basically the ones who find and exploit security vulnerabilities for their own personal/political gain.

    That's a Windows problem. And still, I'm almost certain that an app like explore2fs won't allow you to write to the ext2/3 partition (but it cold still be formatted).

    Alright, but this not the issue for desktop users is it? I suppose it's regarding servers, right?

    I never said Windows was insecure, but that Linux were safer. One point as you said, root/admin is not enabled by default. This has been fixed in Vista though (UAC), but in such a way that many disables it.

    I heard it in almost every thread regarding viruses on this forum. There's a reason for ClamAV picks up Windows viruses isn't it?

    IPTables is turned off by default. You do not need Firestarter to restrict ports, but most people prefer a graphical frontend.

    A desktop computer is an unlikely target for a "hacker" or "cracker", but if someone were spreading viruses/worms around they would try to infect anyone and anything. Not that they'd get far....Servers are more on the receiving end of direct attacks by someone trying to get unauthorized access. A much bigger issue.

    I wasn't disagreeing with you, simply saying that Windows could be secure.

    ClamAV probably shares a database with both clients. I don't use AV software because there's no need for it. However, I think it's just in case you've already let it spread. It can't write to the root folder without the permissions.

    IPTables is never "off" as far as I know, but there are generally no rules by default.

    The ext2IFS driver at fs-driver.org allows you to write to ext2/3 partitions.

    And you're right, it is a Windows problem, but a problem nonetheless. If someone downloads a windows virus in Linux and saves it on an ext3 partition, then mounts that partition in Windows, they can run the virus. Of course if they had anti virus sortware for Windows with some sort of constantly running protection thy might not be able to run the thing. It's not something Linux can do a lot about.

    This isn't because linux allows the virus to spread, it's because infected files can be sitting on a linux system (doing nothing harmful) and get passed on to a Windows system (where it will do something harmful).

    Linux users use ClamAV to make sure that everything on their system is clean. Files infected with Windows viruses will not do anything to linux.
