Preventing Future Installations
Chances are, if you had no idea how Safari had installed itself on your desktop it may have been included when you were updating older versions of QuickTime or iTunes. Any time you update one of those programs (assuming you use either one), you will have to update them through Apple Software Update. Safari is included as optional software and you may have installed it without wanting to. There is a way to prevent Safari from installing on your computer again. In your list of programs under your Start menu, look for Apple Software Update.
As soon as you load it, the program will search for software updates or new software for you to install. Lo and behold, there’s Safari 5 listed under New Software. If you don’t want this update anymore, make sure the box is checked, and then click on Tools. Scroll down to the option Ignore Selected Updates and the program will vanish from the list.
If you want to restore the program at some point in the future, you can select Restore Ignored Updates, also under Tools.
After completing these steps, Safari should now be both gone from your computer, and should not be offered as an option from Apple from whenever you decide to run Apple Software Update.
