It's not likely a firewall would prevent spyware from getting onto your
computers. For a program that keeps reinstalling themselves, you will need
to find a browser hijacker removal program. Anti-spyware programs won't work
against these hijackers usually, as they keep renaming themselves all of the
time.
Your simplest course of action against a hijacked browser is to stop using
Internet Explorer and start using Firefox instead. Once you get used to FF,
you'll wonder why you ever used IE.
If you're running with Windows XP and have downloaded the Service Pack 2,
then that installs an updated version of IE that has an "Manage Add-ons"
option under the Tools menu. It will list all programs that have attached
themselves to IE, and allow you to unlink them. Some of them may be
legitimate tools, such as the Yahoo or Google toolbars, perhaps the
Macromedia Flash plug-in, etc. Others you'll have to think about and find
out what they do.
If you aren't running Windows XP SP2, then you can still do uninstall IE
add-ons, but you'll have to download a program called HijackThis! to do it
(completely free). Again, just like with Manage Add-ons in the previous
example, this thing will list a combination of legitimate and illegitimate
add-ins, it's upto you to figure out which ones are which.

If you're running something like ZoneAlarm or Sygate personal firewalls,
they all have an option to allow full internal network links amongst a
trusted network of machines. You once you activate that, then the nodes will
be able to talk to each other as if the firewalls didn't exist between them.

Sure, most of the personal firewalls will all you to do that. They can all
be configured to recognize the local subnet and treat it as a trusted zone.
