My brother recently went to college and since he's been there his computer has been hit hard with a lot of spyware and viruses. His Norton antivirus is catching most everything and I've had him use ad-aware and Spybot. Though he keeps getting slammed with stuff. I'm about to have him start using FireFox instead of Internet Explorer to browse.
My question is...is there a firewall program or something to that nature that we can get for him that will help him stay more secure on the network at school? I read somewhere about a NAT router. Is that even possible to use in his case? Anyways, any input or suggestions would be much appreciated! :o)
