I have a computer I was gifted and it has Norton 360 installed and it is controlling the Windows security actions. The issue is that Norton is regularly popping up with issues showing to be corrected. Thousands of files that are not needed and apps slowing down computer. It can fix it but not unless I pay more and the the subscription price is lots after that.
If I uninstall Norton, will windows security automatically be activated?
I have read that to fully uninstall Norton I need to download the Norton removal tool from their website. Is this correct?
Thanks

It can be incredibly frustrating to have a gifted computer bogged down by constant upsell pop-ups. What you are experiencing is very common with pre-installed or standard third-party antivirus software. They often flag thousands of benign browser cache files or harmless temporary data as "issues" to create a sense of urgency, only to lock the fix behind a premium optimization paywall.
Here are the direct answers to your questions to help you clean up your machine:
Yes. Windows has built-in, real-time protection called Microsoft Defender (Windows Security). Windows is designed to detect when a third-party antivirus is active and automatically step aside to prevent software conflicts.
The moment you completely uninstall Norton and restart your computer, Windows Security will recognize that it is now the primary line of defense and automatically switch back on to protect your PC. It is completely free, runs quietly in the background, and is highly rated for modern threat protection without slowing down your system.
Yes, this is highly recommended. While you can start the uninstallation process through the standard Windows Settings menu, third-party antivirus programs are notorious for leaving deep registry entries, background services, and leftover folders behind. These leftovers can sometimes glitch and "trick" Windows into thinking Norton is still there, preventing Windows Security from turning itself back on.
To ensure a completely clean break, follow these steps:
Download the Official Tool: Go to the official Norton support website and search for the Norton Remove and Reinstall tool (sometimes referred to as the Norton 360 Remover).
Run the Tool: Open the downloaded file. It will give you options—make sure you select the option to Remove Only (do not select the reinstall option).
Restart Your Computer: Once the tool finishes its job, reboot your PC.
Verify Windows Security: Click your Windows Start menu, type Windows Security, and open the app. Check the Virus & threat protection tab to ensure it shows a green checkmark and states that Microsoft Defender is active.
Once Norton is gone, those aggressive pop-ups will disappear, and you will likely notice your computer running much faster and smoother!

The Norton Remove and Reinstall tool is the recommended solution to completely remove Norton from your system. Once Norton is uninstalled, Windows Security will activate and take action on your system security.
AI answer
Uninstalling Norton 360 will allow Windows’ built-in protection (Microsoft Defender Antivirus and Windows Firewall) to take over, but it is important to ensure that at least one security solution is active at all times.
When a third‑party antivirus such as Norton is installed, it typically disables Microsoft Defender Antivirus. After Norton is fully removed, Windows Security should automatically re‑enable Microsoft Defender and Windows Firewall, provided no other third‑party antivirus remains installed.
To remove Norton:
While Norton is being removed, the device is in a reduced‑protection state. Ensure that Windows Firewall is enabled and avoid downloading or opening files from untrusted sources until Microsoft Defender is active again.
If more than one antivirus or antispyware program is installed at the same time, the PC may experience decreased performance, instability, or unexpected restarts, so keeping only one active security suite (for example, just Windows Security) is recommended.
