Can norton security be installed on my apple ipad

You don't need it, and there is no real version of it for iPad.

The Norton mobile Security App only scans on demand. Due to the way iPadOS is built it cannot be active scanning anything but itself and your active Wi-fi connection when you open it.

Its pointless to have it on an iPad, as there are no viruses or malware that can affect an iPad.

Please do not install it.

Go to the App Store on your iPad and in the Search option at the bottom right, type Norton. That will take you to the app. Tap that to bring up the download.

You don't need that program your iPad. It can interfere with normal operations.
