Should I run Norton360 on my MacBook Pro? I have just replaced my Dell.

No, it is not recommended.

Third party anti-virus does nothing on the macOS except add issues and compete directly with Apples own built in security.

Instead of Norton360, you can periodically run a scan with a free program called Malwarebytes. It can be used to quickly remove any malware that has made its way into your Mac.

I also suggest that you read these articles:

macOS contains various built-in security measures, such as Gatekeeper, which verifies that downloaded apps come from developers who are registered from apple.

The best way to protect yourself is to understand where malware comes from and how to avoid it. You should also keep your software updated to ensure that your Mac is using the latest built-in security and that bugs/vulnerabilities have been patched.

✋🏼 Please NO! The last version of Norton that did not cause Mac owners issues was released in in 1999.

The only threat to Macs is adware—a self-inflicted wound about 95 percent of the time— and most anti-virus apps ported from Windows do a poor job of detecting adware.

The macOS protects itself and and, catlike, even self-cleans automatically. When you add useless third-party "protection" utilities like anti-virus and worse, so-called "cleaning" apps, they compete with the elegant systems you paid Apple to build into the system. Trouble follows.

That stuff WILL make you pay with continued performance and stability problems.

Your title very concisely includes another reason not to install:

"I have just replaced my Dell."

Please treat your new Mac like a Mac, not something else.
