QUOTE: "Or is an iso file direct off another cd you can't change or add anything to the .exe file. Thx"
First you wouldn't add anything to a working executable file. An executable type file generally starts up the rest of a program. An iso image on the other hand is similar in some ways to a zip file where you edit, add, or remove items from it. Although some exe type files can be modified by programmers any change on a default executable for software by the user can spell disaster. A corrupted exe file can act like a virus at times. The only way an iso image would contain a virus would be when the iso image contained files from an infected machine. (Then you could have all kinds of bugs running around!
