I would guess that you didn't use MS Update to PATCH your machine and
that you have file/printer sharing enabled on a PUBLIC IP address and
were not running any firewall or virus software.
The problem with ZA, BI, etc... is that if you don't properly configure
them, or if you allow something that you don't really understand, that
you will get hacked.
A router is your primary line of defense - it blocks ALL inbound
connections unless your computer invited them in.
Quality Anti-Virus software is the next.
Running Microsoft Update every evening is the next step.
Running Microsoft Office Update every week is a good thing to do also.
Since you said Windows 2000 - I would assume that you may have IIS and
FTP and SMTP services installed - if you are not using them then you
should remove them.
Once you get the $50 linksys router you should download the free
WallWatcher program and enable logging in the router. It will clearly
show you what is going IN and OUT of your network.
No one I know that is using a Linksys router between their network and
the internet was effected by the Blaster worm (or the slammer or any
other worm) in more than 3 years.
There are many other things you can do, but if you do everything above
you should not have any problems with uninvited strangers.
Remember - if you get an email, even from someone you know, and it has
an attachment, and you didn't ask for it, don't open it - even your
friends can send you infected files (or macro's) once their machines are
compromised.
