I have recently purchased Norton 360 to replace Kaspersky Internet Security: however I have discovered only today that it covers only one device. I wish to upgrade to Norton 360 Deluxe since my tablet has also Kaspersky installed. I think Kaspersky had been hacked since it was affecting other sites, since corrected by Norton 360.
How do I achieve this upgrade?
First you need to remove Kaspersky from your computer. You should only have one real time security product running at a time. Having more than one installed can actually reduce your protection as the two products fight for system resources. You should download and run the Kaspersky removal utility from https://support.kaspersky.com/common/uninstall/1464
To change your subscription level, you need to contact Norton Support and ask them to help with this. www.norton.com/contactcs
