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

rm: CrashPlan.app: Operation not permitted

##############################################################################

HXXXX:Applications sysop$ ls -al Crash*

-rw-r--r-- 1 root admin 0 Mar 19 19:17 CrashPlan.app

##############################################################################

HXXXX:Applications sysop$ sudo chmod 755 CrashPlan.app

WARNING: Improper use of the sudo command could lead to data loss

or the deletion of important system files. Please double-check your

typing when using sudo. Type "man sudo" for more information.

In recent versions of OS X, the system-immutable (schg) flag can be cleared by the superuser without booting in single-user mode.

Thank you. It's been a long week. This started last week and I've been exhausted and to tired to think straight. I even called AppleCare twice - no resolution and my foggy brain wasn't able to recall the right unix commands. I was on the right track having tried a few things in single user mode. Linc - I don't know at this point about your point about not having to go into single user mode. Since the fixed worked in that mode.
