yea i pretty much gots the same problem.....if u can find out the software thats preventing u from accessing sites, u can remove it from the registry hive.......but make sure u kno the right binary key, as deleting the wrong one may permanently damage the OS and ull have 2 do a system restore.....

but ninjaproxy is a schweet proxy....and u can always go into https:// which is a secure mode of browsing

sometimes using firefox also allows u to navigate through the IE explorer firewalls.......

hope that helped
