MacBook Won't Connect to internet

[darkdefeat2030]

I'm new with mac. I have a mac book osx version 10.4.11. It has 2.16 GHz intel core 2 duo processor, 1G ram. Anyway, Its running on a D-Links cox cable router. Two other non-mac computers are running off of it just find. I reset the router and tested the connection and it says i'm online. When I try to go on firefox or itunes or any thing that needs internet it don't connect. Is it a virus? Can you recommend a virus protection adware as well.

There ARE no viruses in the wild that affect Mac OS X.
No antivirus software can detect a Mac virus, because no Mac viruses exist.
There are trojans that exist, but these can be easily avoided if:

• you are careful what applications you install
• you are careful where you get applications
• you never enter your administrative password without THINKING!
