Hi All! I replaced my Norton System Works on my desktop and Norton Internet Security on my Laptop with PC-cillin Internet Security 2005 this past weekend. The two computers are linked via wireless network. Prior to installing PC-cillin, I was able to share files. After, I was not. I spoke to tech support and they had me remove the firewall option in PC-cillin, saying that it is the same as the firewall built in my Linksys router. I am able to share files again, but I have a concern I thought one of you might shed some light on. The PC-cillin firewall has a setting for wireless networks. What good is that since most wireless networks use a router with firewall built-in. Also, when I take my laptop away from the network, I guess I will have to manually reinstall the firewall? Can anyone advise me as to whether I am missing something here. It would seem to me that I should be able to use all the features that come with the software. As always, thanks for your sage advice.
