Imp68 - There is no items in Startupitems folder at all.
andyBall_uk - yes, I found a file safariextz that bitdefender uses to reinstall the addon to, and trashed it. reboot my pc, and volla its back.
call me stupid, i even removed my user account and deleted all files associated with it, just to see if this annoyance can go away.
its all because, I tried to install Bitdefender Antivirus for Mac. Trial from their website. Now their .dmg file comes with an uninstaller. But running it, doesn't do anything. I rebooted my pc several times, only to get disappointed. This is increasingly becoming frustrating, i am even thinking about wiping my mac clean and reinstalling Mac OS X Mountain Lion all over. ( A guy with no home, living off public wifi, and motel wifi, it isn't easy to download 4.4GB file, which requires 44 hours plus according to download manager, so I am trying to do anything and everything that can help me not to reinstall a fresh copy of OS ).
