360 Premier Locked

360 premier on a gateway all-in-one computer with windows 7 has locked itself  and completely blocked access to the internet. Norton Autofix reports 8504, 104 but can't correct the problem. Downloaded the online tools to fix 8504, 104 on another computer and transferred them via CD but without internet they are useless. Tried to uninstall 360 via windows, but that did not work.  Additionally windows connection wizard won't work.  Norton Utilities is working normally and the rest of the computers functions appear normal. Suggestions on how to uninstall and/or get internet back.
