Hi Sam - Thanks for your opinion, however https://www.av-comparatives.org/comparison/ disagrees with you? Latest industry-wide tests have Gen products (Avast, AVG and.. Norton) as the *ONLY* protection blocking 100% of attacks with lowest system impact of all vendors. Perhaps it’s time to update your opinion with this FREE 6-month trial? Hope this helps - DWN

Thanks for your feedback. If you're interested in a third-party perspective on Defender, there's a helpful comparison video that puts both Norton and Defender through the same malware tests. It’s quite eye-opening: Norton successfully blocks all the threats, while Defender unfortunately doesn’t hold up as well. You can check it out here: https://youtu.be/S9LPxOPiYqU?si=ot2Bo4lSLd8nMyyN&t=448

Hi JessicaB,
Thanks for sharing your experience—and I’m really sorry to hear your computer is still running slowly. We know how frustrating that can be.
Norton 360 is designed to protect your devices without getting in the way, but performance can vary depending on your PC’s specs and settings, and sometimes a few quick adjustments make a big difference. If you’re open to it, here are some steps that often resolve slowdowns:

Run a Smart Scan & Update Everything
Open Norton 360 → Security → Scans → Smart Scan. Also make sure Windows/macOS and Norton are fully up to date.

Check for Conflicts with Other Security Apps
Running more than one antivirus or firewall can cause heavy slowdowns. If there’s another AV installed, uninstall or turn it off.

Adjust Scan & Background Settings

Schedule full scans for off-hours.
Turn on Silent Mode during gaming or heavy tasks.
Temporarily turn off VPN when you’re on trusted networks to see if that improves speed.

Reduce Startup Apps
On Windows: press Ctrl+Shift+Esc → Startup tab → disable non-essential apps. Fewer boot items = faster load times.

Free Up Space & Check Disk Health
Ensure at least 15–20% free disk space. On Windows, run Disk Cleanup and consider Storage Sense. SSDs benefit from firmware updates.

Look for Resource Spikes
Use Task Manager (Windows) or Activity Monitor (Mac) to spot apps that use a lot of CPU or memory and close/adjust them.

If you’d like, we can help you step-by-step and tailor this to your device model—just let us know your operating system and any other security apps installed. Your peace of mind matters to us, and we want Norton 360 (and LifeLock) to feel protective, not intrusive. If you are still facing issues please do not hesitate to get in touch with our support team here www.norton.com/support

Hi Roberto - Thanks for your feedback, but if you really want the #FACTS on Windows Defender, watch this 3rd-party comparison of Norton and Defender.

Hi Kim - Thank you for reaching out. Sorry for your confusion, but this is *absolutely* a FREE 6-month subscription that thousands of BBY customers take advantage of monthly. We take a credit card like any other subscription service these days (Netflix, Amazon Prime, etc.) but there’s NO initial charge and you can cancel renewal at any time, including immediately after activating the license. You then get half a year of device, scam and identity protection from the best service in the industry for over three decades! Hope this helps and you reconsider - DWN
