should File/Program be deleted?

Sorry all to bring up a Adobe issue again, but it was actually on the Norton Threat Explorere that the whole reader 8 security issue was raised.

 

Along with reader 9 is something called Adobe_Updater.exe. I googled and found all kinds of people talking about deleting this, taht it is a security risk. Seems odd to me taht it would be a security risk, since it is digitally signed by Adobe.

 

1. Should this be deleted?
