MacBook Pro won't start since deleting various files I removed some ".dylib" files because BitDefender Virus Scan told me so. I wanted to remove all of Genieo's stuff but I presumably missed the "launch.conf" file. Had no access to it.

Now my Mac freezes while starting up. The big problem is that the DVD-drive is out of work since a long time ago, so I can't reboot with the installer disc. Also safe mode doesn't work.

I think I have OS X 10.6.9 on a MacBook Pro
Use single user mode to remove launchd.conf
