Installation question

I am installing 360 onto a new laptop that has a recently expired trial version of Norton IS and I'm not sure what to do next.  Durring installation, I got a message from the instal. manager that said it detected the following proxy settings then listed an address XXX.X.X.X and a port #.  It said that if I didn't specify these settings, that malware may have set these settings and recommended changing or clearing them.  I also have the option of choosing "do not use proxy settings".  I am on a home network with a wireless router/ access point.  What should I do next?
