Hi,
One of the girls at work has started getting this message everytime she starts 
up her MacBook and asked what should she do about it.

The message is

"An item in the startup Items Folder (Library/StartupItems/hexSleeperX.app) 
does 
not have the proper security setting. Closing this item may cause problems. 
If you trust this item and want to fix the security settings, click Fix. 
To always prevent this item from being used, click Disable.
To stop using this item and show this message again, click Decide Later.
Decide later Disable Fix"

Suggestions? Advice? I've never seen it before.

TIA

Maureen
