The NAV auto protect functions CANNOT switch ON @@
 

after i installed the longhorn , the norton AV 2003 pro & Internet Sec,
can't autoprotect , it said some virus or somethings doesn't
allows me to do that,, is it incompatible with longhorn O.o?
fine now , i installed the Mcafee v ,

could be incompatability with longhorn. Don't know for sure, don' t know anyone else trying to run it, it's still in alpha testing probably, let alone beta which will still be bad.
