There are several options for a small business to obtain inexpensive
protection...

A couple of methods:

1. If you have a small number of machines to protect you can use one of the
private software firewall on the market (such as BlackICE or ZoneAlarm) and
at least have some filtering in place (if you use the "commercial"
versions - not the free ones - you can also do email attachment filtering).
I personally am using the pay version of the ZoneAlarm software as a
secondary firewall on my machine and have not been hit with any of the virus
attachments to date because of the attachment filtering).

2. Use a SOHO firewall product such as been previously suggested although I
would add the WatchGuard SOHO to the list as well. They have released a new
version of their software (firmware) for the product and it has all sorts of
added features you find on more expensive firewalls and is easy to
administer (read: you don't need to be a Masters Degree in Computer Science
to set it up and use it) - it even has the capability to allow remote users
to access the trusted side of the network using IPSec VPN.

3. The least method would be using a Network Address Translation(NAT) router
or Port Address Translation (PAT) router with internal private network
addresses for your network - but - you are relying on your ISP NOT to pass
the private network addresses through their routers to preclude direct hack
attempts (can be done but not as easily as some would lead to believe - you
have to steal the TCP session to do it)...

I realize most small businesses getting started do not have the capital to
invest in a medium range firewall and the above are suggestions I give a
small business - most can be implemented by someone with a basic knowledge
of firewall security practices for less than $600 or so - of course it is
more expensive if you have someone do the configuration and installation...

Personally I tend to lean towards the WatchGuard SOHO solution myself (and
use one too) as it seems to have the greatest number of features (especially
the IPSec VPN capabilities for remote connections) and it can be setup and
used by most anyone (uses a web-based configuration menu or can be remotely
administered through an IPSec VPN link using WatchGuard's remote management
software - but the SOHO has to be configured for that first since there is a
shared pass-phrase used for the IPSec key generation)...

Of course - all of the above is for naught if things are not configured
correctly - even on the big firewalls....

just food for thought...
