How can I remove ASUS InstantOn, if I can't find it in "uninstall program" menu?
Try using Revo Uninstaller. Even if it can't uninstall the application normally, it will force it to uninstall by wiping out all traces of its presence from the system.
After that, try running AdwCleaner to make sure that there are no leftover rogue registry keys or toolbars in your system.
Alternatively, use CCLeaner to remove the item from startup using Tools > Startup inside CCleaner's interface.
