How to Download and Setup Norton Security in my Dell Laptop?

Hi Ashley_360,

Thanks for posting.  Apologies for the confusion over antivirus software.

Windows 10 comes with full Anti-Malware software which is Windows Defender and you don't need separate product. But for whatever reason, if you want to use third-party Anti-Malware products, you could do it and it will disable Windows Defender.

Here is a short video from the Norton website you may find helpful:

You didn’t specify what version of Windows you’re using, but if it’s Windows 8 or newer, Windows Defender is anti-virus that’s built-in, and Defender these days compares very nicely against third-party solutions, even the paid ones. If you have Windows 7, you can download Microsoft Security Essentials for free.

I personally do not recommend third-party anti-virus, especially on Windows 10, for reasons I wrote about in this thread: https://www.dell.com/community/Inspiron/Disadvantage-of-Removing-Antivirus-from-Laptop/td-p/7264019

If you think you already have issues, then you might want to try Windows Defender Offline, which allows you to create a bootable scanning tool that can check your system from outside Windows. That can be important for rootkits that can hide themselves from anything running within the OS they’ve infected.
