HELP!!! Recovery Disk Wont load

After running NIS 2010 for the first time windows will not reboot.  The windows error says a virus may be preventing it from loading.  I have tried to boot from the Norton recovery disk (both the one that came with it and on I created off the web site) Both go through a "Window Loading" bar then go to grey background and bring up a window that says "trying to install ms_tcpip6" and they just sit there.  Any ideas???
