Hello Efpalinos,

I understand you have received a prompt to update Apple Remote Desktop on your computer, and you are wondering what this program is.  Is your computer part of a network of computers at your place of business or school?  If so, it the application may have been initially installed by your network administrator.  Here is some information on Apple Remote Desktop.
