Unable to Delete Application File

All:

I've got a damaged Application file in my Applications folder. The icon for the file is represented by a grey/white icon with a circle/slash on it. If I perform a CMD+I and I use the lock to unlock access to the file I cannot make any changes to permissions, etc. It is zero bytes. I have not been able to use it in a terminal shell using SUDO and root. I cannot toss it in the trash, etc.

Some information from Unix terminal shell...

HXXXX:Applications sysop$ rm CrashPlan.app

override rw-r--r-- root/admin schg for CrashPlan.app? y
