Why Does Norton Slow Down Your Computer System?

Last Updated on November 15, 2020

An antivirus program is a must-have for any computer system operating in the modern cybersphere. It serves to equip the PC with the necessary tools and features needed to counter the attempts of third parties to break into the system and steal or delete personal data. Norton.com/setup Antivirus is one of the most popular antivirus programs that is used all across the globe in all sorts of applications because it provides complete security from all kinds of cyber threats. Unfortunately, not all is a paradise in the world of Norton.com/setup users. Many Norton customers report that their computer system has slowed down after they have downloaded and started using Norton.com/setup Antivirus on their PC. Why is this so?


A slow or poor performing PC will lag, experience glitches, show you random pop-ups, and interfere with the various apps and software you use on your computer, causing them to crash frequently. There are many reasons why this can happen, including the following:

Poor System Compatibility

You should make sure before downloading the Norton.com/setup software that your system fits the minimum requirements for the application to function optimally. System lagging usually happens with the antivirus program if there simply isn’t enough RAM available for it to perform its function properly.

Secondary Antivirus Programs

If you are running or using other antivirus or security software on your computer in addition to Norton.com/setup, it can cause the latter to start acting up and impacting system performance. Antivirus programs typically launch when you turn on your device, so the presence of two different apps can cause conflicts and hog the system down.

Process of Updating

Norton Antivirus may occasionally slow down your computer during the period that it is installing the latest updates. To do this, the app connects to the Norton server to download the released patches, a process that can be RAM consuming and thus bogging down the speed of the system.


You can try using the following tips to improve system speed while using Norton.com/setup Antivirus:

  • Free up space on your disk by deleting unwanted documents, applications, and temporary files.
  • Run Disk Cleanup.
  • Uninstall any other security software on the system.
  • Stop background applications by ending them in the Task Manager.
  • Find and remove any damaged or corrupted registry entries in the Windows system registry files.
