    Maybe a lot of /. readers are too young to remember real viruses, or to have played around/collected them, but its been a decade since a real infectuous virus has gone around.

    If it can't infect any arbitrary EXE file, its not a virus, its a trojan or a worm, depending on wether or not its a moronic user or a security hole that allows it to enter the system.

      I agree trojans aren't viruses, but worms are exactly the same thing as EXE viruses except at a bigger scale -- instead of merely infecting EXEs on one system, it infects systems on a network.

      The main reason we needed to have a copy of the virus in every executable was because we were running on DOS, which doesn't usually support multiple programs running at once. And a lot of networks were little clumps of networked file systems.

      Now that the most common OS's support multiple processes at once, and the internet/web/email is the main thing that connects everybody (and writable network file systems are mainly only found in the workplace), viruses have naturally changed.

    "There's still a big perception out there that only broadband users need one," Lee says. "Everyone needs a firewall, along with antivirus."

    This rings all too true. If forwarding ports for certain applications wasn't such a pain in the ass, I would say make ISPs require firewalls or find a way to have some sort of personal firewall for their connection that they can access from the internet and change the settings on. Just a thought.

    This would bring up other problems, but it'd at least stop a lot of problems with trojans and open relays.

      That would be fairly easy to set up. An ISP could provide a web interface to configure per user "pin holes". Default to blocking all traffic from the customer, and some traffic to the customer (smb traffic, for example), and let them enable things if they need to. Not hard to do at all, as long as arbitrary "thou shalt not use port X" policies aren't brought in along with it.

      That may be true for a Windows machine where controlling the number of open ports is difficult and where you have every piece of software calling home, but on my Linux laptop, I don't run a firewall. I just don't see the need. I've got ssh open and that's it. And X, from which I haven't heard anything since 4.0.

        Well, unless some evil program hits you and opens up another port. And that is were the firewall comes in - second line of defense. Even if someone evil manages to open up a rootshell, the packet filter will not allow any connections out or in.

      How...

      ...does that evil program break in and get run if the ports are not in use?

      ...does the evil program abuse a port if the software using that port is secure?

      ...do you protect your firewall once the evil program is on the same side as the firewall and all your other apps?

      While firewalls are useful at times, they are not magic. They are tools and not always appropriate.

No amount of emergency IT sessions with the staff explaining precautionary tactics involving attachments is going to change that, and if any psychologist recruitment is necessary it's to explain why the average person keeps clicking attachments to messages in obviously broken English.

    But how often do you run across a computer you have to service with expired virus subscriptions? It seems to happen to me quite a bit. I suppose M$'s virus scanner mentioned earlier on /. might help, but that reeks even more of conspiracy than the current "protection money" setup does.

    Rather than bundling a questionably legal virus scanner into their next service pack, Microsoft should perhaps add a tool that helps to lock down permissions on NTFS volumes, creates unpriveleged accounts for users and various services, etc. Even with the multitude of security holes, Windows can be made a lot harder to mess with, if you put a little work into.

    Your other suggestions are sound, as far as they go, but unfortunately most people will deliberately run with administrator privilege if they can, and there is still the fundamental problem that the OS does not run if system files are write protected. OK they can be protected from regular users, and it helps, but is not sufficient. But, I think you are saying that it should default to the most secure settings out of the box, instead of the opposite. People like us have been saying that for years, to no effect.

    When the virus sends itself out, have it send an email containing a simulated conversation between two college students planning a weekend out. Have the conversation end with the comment of sending the pics of the weekend as a slide show or something. Have one of the email addresses (visible in half the replies) be one character off the target email address.

    So now our victim sees a conversation between two college students plannig a weekend out and sees reference to attached pictures in a slightly odd format. Follow up immediately with another email in a paniced tone explaining that the pictures were sent to the victim in error due to a typo in the email address and please delete them as they contain some embarrasing half/fully naked pictures.
