Download and burn to CD a firewall (BlackICE or whatever), firefox 
and AVG updates. Take to your friend's and do a clean OS install, 
then install the firewall (close all ports incoming), firefox (use 
this browser rather than IE) and AV updates.

Open the manual for the lynksys and read it. It will instruct you on 
connecting your machine to it via ethernet and then using your 
browser (if required) to complete the setup. Its probably a NAT 
router so that means you have "internal" addresses such as 
and external address which is provided by your ISP via your Netopia 
modem (as a note I am not familiar with all the Netopias but you 
might also have NAT capability there also so check the manual)

After that you should be good to go.
