Welcome
As you only have 360 with 3 installs you do not have a version that can give you support for your iPad. You need to have the 360 Multi Device version that will cover 5 devices, from PCs to mobile devices.
Having said that, you will not actually install 360 on a mobile device, but Norton Mobile Security. Check the Compare tab of the 360 MD page here, and look for IOS in the descriptions to see if it provides any features you need. http://us.norton.com/norton-360-multi-device/
