Why Norton 360 Turns Into a System Nightmare
Norton 360 presents itself as a complete security suite, yet many Windows users discover a very different reality. Although it promises protection, it quietly introduces severe slowdowns, unexplained glitches, and unpredictable system behavior. Users often spend weeks troubleshooting strange issues without realizing Norton caused them.
Moreover, Norton does far more than slow a computer. It interferes with file operations, blocks legitimate apps, breaks network connectivity, and injects itself into many parts of the operating system. Because it acts silently, diagnosing the root cause becomes extremely difficult. Many users only find the real problem after they disable Norton and watch their systems return to normal.
In addition, Norton fails to deliver the strong protection it advertises. It drains system resources, hurts performance, and disrupts normal workflows while offering little real-world security value. Quite a few users even say Norton 360 behaves worse than malware because it destabilizes Windows without an obvious benefit.
- It slows down Windows and interferes with everyday tasks.
- It blocks safe applications and prevents normal file deletion.
- It creates hidden disruptions that mimic system failures.
Because these problems occur silently, Norton 360 functions more like an obstacle than a security tool. This review examines why so many users report similar issues, how Norton creates them, and why Windows often runs dramatically better once users remove or limit it.
A Decade of Silent System Sabotage: A Customer’s Battle with Norton 360
One of our long-time customers shared a striking example of how Norton 360 caused years of frustration. Since purchasing Fast Duplicate File Finder (FDFF) in 2016, he has experienced persistent problems with deleting files. Over the last decade, he worked across multiple FDFF versions and three major Windows operating systems-Windows 10 Pro (32-bit), Windows 10 Pro (64-bit), and Windows 11 Pro for Workstations (64-bit)-on two different workstations: a Dell 490 and a Lenovo P330. Despite numerous updates, drivers, and ancillary software, the issues have never been resolved.
The files he tried to scan and delete were both local and on network-attached storage. What stood out was that every environmental change-new OS updates, hardware changes, and other software installations-failed to fix the problem. FDFF remained the constant, revealing that the interference came from Norton 360. Even though he was paying for a premium security suite, Norton silently caused countless issues on his system, blocking normal operations and even disrupting our software.
This real-world case illustrates the hidden dangers of Norton 360. Users can spend years troubleshooting mysterious errors, system slowdowns, and blocked functions, all while believing their antivirus is protecting them. In reality, it can act as the main source of system instability.
Here is how he solved the problem and why he will probably Stop Using Norton 360:
“Interestingly, there have been no errors or messages in the Windows System logs nor any messages in the records of the anti-virus or malware software indicating blocking FDFF to indicate any difficulties — a note on this below, and I even have FFDF white listed in my current program Norton 360.”
Even with Fast Duplicate File Finder white-listed and key protections disabled, Norton 360 silently interferes.
Again, thanks for the workarounds has having those I was able to change enough settings in Norton 360 to learn that, although no interference was being logged, I had to disable Exploit Protection manually for FFDF to be able to delete the files without interference. If anyone else is using Norton 360 whom you need to assist, the option is located under Settings> Features> Exploit Protection. Once one selects the green slider next to the label

Even this temporary workaround highlights Norton 360’s poor design and hidden interference.
After which a confirmation dialog is presented (not shown), and one is returned to the main page.
Norton 360 displays a red warning even when the user restores normal system operation.
That nothing was logged in Norton’s report strikes me as rather odd.
