i am using wired edimax router (br6104k) and i enabled the firewall feature in it with all the options.
Do you think that this built in firewall is enough to protect the computer from "outside" problems ?
i also use AVG free antivirus and MS SPYWARE.
I had no problem till now, but 2 of my clients which did not have a router and a firewall had a nasty trojan that they got rid off only after installing NIS 2005.
