I was able to resolve the Windows 7 BSOD (nwifi.sys) problem by stopping & disabling all the Symantec processes. I do have one last question. Is SEP v11 supported with Windows 7? If so, how do I get it working?
Right click on 'my computer'
select "Manage"
on the left pane, open services and application
select Services.
on the right pane you will see a list of services.
right click on Symantec.
click on properties
stop the Symantec process
change the startup type to disable..
reboot the computer..
