If you check your Windows services or your latest HijackThis log, you may find a new entry: the Install Driver Table Manager. We've gotten a lot of requests recently asking what this is, so we decided to poke around and find out.

It appears that this file originated from the InstallShield line of application installers. It is supposed to only be used when installing a new program on your system (like when you run the setup.exe program). However, Apple's iTunes 5 added this entry into the Windows services, and it doesn't even seem to be necessary!

It's important to note that this program is not spyware. However, you can set it to "Manual" so that it does not start up automatically when your computer starts. To do so:

- Right-click on My Computer and choose Manage.
- Then expand the Services and Applications section and click on Services.
- On the right-side of the screen, find the entry for InstallDriver Table Manager and double-click on it.
- Change the Startup Type: to Manual.
- Hit the OK button and close the Computer Management screen, and you're all done.

You can run iTunes normally after doing this step. iTunes doesn't seem to access this service at all, so it may just have been sloppy programming on Apple's part (they don't always do well when porting their Mac applications like iTunes to Windows).

Note: If you are looking for this entry with HijackThis, it will appear as an O23 entry.
