I have Norton Internet Security and can login to Xfire! Why?
As of the 2005 edition, go to Norton Personal Firewall. Click Configure. Click Custom Level. Then check the box that says “Enable Control Access alerts”. Then Norton will give you a pop up that allows you to permit Xfire to connect to the internet. You can also do this manually. Configure> Programs tab> Click Add. Browse to the xfire.exe. (Default is C:\Program Files\Xfire) You may need to also add xfire_exception.exe to the list as well. You will have to repeat this everytime Xfire updates, since the firewall will view Xfire as a new or changed program.
