Because machines can be infected from USB memory sticks, CDs, exploits on web pages and the list goes on and on we not only protect the network but each machine from the others.
Given that such protection can be free why wouldn't we?
Ive been wondering why when you have a network of computers in your home, why you would need security installed on each computer?
The router is suppose to be firewalled, and shouldnt the main computer be serving all the security for all computers for the virus portection?
Also, when your connected to a network isnt there a program that you can use to chat to each of the computers, without signing up and regesitering to use?
Im not having issues just wondering what others are thinking about this, so it can make more sense to me. Thanks
