Warning: SUID file ------will not be repaired.

Hi:

When trouble shooting some difficulties in a game I was directed to run

Disk Utility Program ---Disk Utilities Repair Disk Permissions

I ran the program and got this Warning.

Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent" has been modified and will not be repaired.

Should I be concerned? Will it cause difficulties? Have I been hacked?

Pantheria.
