As time goes on, Outlook does not age, and should continue to work perfectly (theoretically), but still continues to not work perfectly. As time goes on, if flaws are found in a Boeing plane that result in a plane crash (not due to aging), Boeing is responsible.

      How about you just educate yourself and your coworkers instead? Email viruses are not just about the program used - they are also about ignornace. Here is a hint to get you started:

      1) Apply all security patches from Microsoft.

      I was just interupted as I was typing this by a coworker asking me about a virus (talk about synchronicity). We don't use Outlook and she wasn't infected but she printed out the email and showed it to me. Sure enough - whatever.scr. I told her to delete it immediately.

      Why did she ask me first and not print it? Because we have a policy here - which brings me to point 2:

      2) Don't open anything that isn't work related.
      3) All computers show all extensions on files.

The email said to email this warning to EVERYBODY IN YOUR ADDRESS BOOK. One of my coworkers received the email and asked me about it. Of course it was a hoax and I wrote an email back to the original sender telling her that she basically just sent out a manual email. If everybody sent out that email to everybody in their address book it would be a disaster. The moral of the story - ignorance is the worst virus.

Time and time again, I have heard it said that this is due to their market share - hackers want to be seen and thus make their virii attackers of the software that most people have. But this really rings hollow for me - the MacOS has always been relatively free of virii, as has Linux, as has BSD, as has AmigaOS, as has BeOS etc. This seems to imply that maybe aside from marketshare, Microsoft engineers (or marketting staff) are doing something wrong.

    Let's take a constructive approach to this topic. With so many SysAdmins out there, what are the TOP TEN things that Microsoft (or any OS maker) can do to prevent virii? I am just a humble Business Analyst, but here are a few ideas that come to mind for me (I hope the coders will forgive my ignorance on some of the finer points):

    10. Disable scripting in certain programs (e-mail) by default.
    9. Automatically download security pactches to PCs if they are of a sufficient severity level (but put measures in place to make sure the same mechanism is not used to transmit virii/worms)
    8. Auto-detect large numbers of e-mails being sent at once and alert users before sending
    7. Make the default install for all systems the most secure install
    6. Create a system to auto-report virus/worm infections to a central (independent) agency for monitoring (user-selectable kill switch for this functionality should be available tho)
    5. Allow purchase of "health insurance" for PCs by Microsoft to reimburse for lost productivity/hardware due to infection - monetary incentive for MS to push quality and security
    4. Create a module of the OS to track virus reports/alerts and display them in the taskbar - produces one trusted source for alerts and to decrease the effectiveness of e-mail hoaxes
    3. Integrate virus alert into mail program for incoming e-mails - advise users when a known large-scale e-mail virus/worm is out there to decrease openning of infected mail.
    2. Give sysadmins the ability to change e-mail setting for all users when a large-scale outbreak is going, to specifically turn off scripting, html reading, java, etc.
    1. Provide a method for a daily audit of all processes running on a machine to identify all those not initiated by the user, and flag those taking part in suspicious activity.
