Good point from both of you. I swear I have never had a virus or anything like it but, to always be protected I guess is the best way to go. Yes I always visit the trusted sites if there is such a thing. I sometimes see a shareware site that is marked as dangerous but, I certainly have not had a problem even with those sites.

As for a firewall though I do use the windows firewall, I almost for sure would rather use the firewall from my router.
