My Dad has just had to buy new Virus protections software that has a firewall too (McAfee 2007).

He has a main desktop PC and a laptop.

The desktop is hardwired to a wireless router and the laptop os wireless to the router.

How would he go about getting the Virus software to protect both computers???

Does he have to install it onto both machines???

Or is there a way by utilising the router? so that whenever the laptop sends and receives the router passes it through the virus software on the main PC........

Any suggestions or advice on how to do this???
