Re: No NetBios share + No Open Port = Safe Win98?

["Luchino - Samel" <samelinux () gmail com>]

May be you can install a firewall on the pc so when you use it you can
view any incomeing connection and block it, but for a home pc, used
only for surf the web [no web are secure, any mail may contain virus
et simili] i think that the router with port blocking is  enought a
good chose and basicaly the best.
A good antivirus help for "bad mail" and remember, the best safe pc is
the the switched off one 8)

Sorry for the bad english
