This may work in removing everything related to the program but then again I'm not sure. When you wish to uninstall something completely:
1. Find the uninstaller .exe file.
2. Right click on it and select properties
3. Under the 'shortcut' tab find the "target" box.
4. at the end of the target address, type "/clean" (without the quotation marks).
exact example) "C:Program FilesZone LabsZoneAlarmzauninst.exe" /clean
This should then remove all files related to the program, or at least that's what my research in killing norton, itunes, and aim had shown.
