I have Verizon as my ISP and have the Verizon Security Suite as my virus protection for my desktop computer. I just bought a laptop and have connected it to the internet through a Belkin N wireless router. Do I need seperate virus protection on the laptop itself? Thanks!

I did a clean install of Windows XP SP3 on my laptop and then when I went to my network connections my wireless is not showing up. I checked all the drives and they are fine and then network adaptor is fine but still not seeing my wireless tried to create a new wireless network and nothing still…I am not that computer savvy so just wanted to know if anyone knew what the problem could be?
It’s a gateway laptop MX6425– my router is a belkin…I’m on my desktop but have my laptop and there is no wireless connection showing only the Network Adapter Connection shows..I already did the whole Download the drives to flash drive then to laptop and still nothing. I looked in device manager and my network adapter is fine and disabled and enabled.
All the drives are installed and fine but still nothing, no wireless connection. I do appreciate the help guys!
