Yes. Norton 360 Deluxe is compatible with a Windows 11 Surface Laptop running an ARM/Snapdragon processor. Norton specifically lists Windows 11 ARM devices, including Snapdragon X Plus and X Elite, as supported.
That said, a few things to keep in mind:
Norton does technically support ARM chips now, but it's not all smooth sailing. A few features just don't work on ARM devices, period — Parental Controls, the Game Optimizer, and SafeCam are all off the table, even though the actual virus protection runs fine.
And honestly, people's experiences installing it have been hit or miss. Head over to Norton's own community forum and you'll find several posts from folks getting a flat-out "this app cannot run on this device" error when trying to install on Snapdragon-based Surfaces and similar laptops. One person even said Norton support directly told them their Snapdragon X Elite machine wasn't supported — despite what the official specs page claims. So take the "yes, it's supported" answer with a grain of salt; it really seems to depend on your specific laptop model and which Windows build you're running.
Microsoft Defender remains the most seamless choice since it's built natively into Windows 11 ARM.
