An odd error with VirtualBox on OSX 10.6

I recently updated my version of VirtualBox on my OSX 10.6 box to version 4.1.8 and it suddenly stopped working. When I tried to start on of the virtual I was given the following error message:

Failed to load VMMR0.r0 (VERR_SUPLIB_WORLD_WRITABLE).


After searching the Internet a bit I found a highly unusually solution. Remove write permission for Other!!

$ chmod o-w Applications

Why this work, I do not know but it does. If you know why, please leave a comment.
