Programs take too long to start or run on your computer

There are several reasons that can cause your programs to start or run slowly. Norton can help you with some of the causes.

Before you follow the steps, make sure that you get your PC tuned up using Norton's performance features. For more information, read Fix computer slow problems.


Restart the computer

  • If you have many applications running in the background, it can cause your program to start or run slowly. Restarting your computer helps you to have minimal programs running in the background.

    After you restart the computer, try running the program that was slow.


Run Norton File Cleanup

    Norton File Cleanup removes unwanted files in Windows Temporary folder. Over time, temporary files can significantly reduce the available disk storage space on your computer and affect performance.

  1. Start Norton.

  2. In the Norton window, click Performance, and then click File Cleanup.


Uninstall any non-Norton security product

    Each security software is designed to work independently on a computer. Multiple security solutions on a computer are generally not optimized to work together, resulting in performance degradation.

  1. Press the Windows + R keys to open the Run dialog box.

  2. Type in the following text, and then press Enter.


  3. In the list of currently installed programs, select the non-Norton security product, and then click Uninstall or Remove.

  4. Follow the on-screen instructions.

  5. When the uninstall completes, restart the computer.

    You can also read the program documentation or contact the program manufacturer for instructions to remove a non-Norton security product from your computer.


Download and run Norton Power Eraser

    One of the most common reasons is that you might have an infection on your computer. Run Norton Power Eraser to perform a deep scan and remove the infection.

  1. Download Norton Power Eraser.

  2. Click Save.

  3. Select the location as Desktop, and then click Save.

  4. To run Norton Power Eraser, double-click the NPE.exe file.

    If the User Account Control window prompts, click Yes or Continue.

  5. Read the license agreement, and click Accept.

  6. In the Norton Power Eraser window, click the Scan for Risks icon.

  7. By default, Norton Power Eraser performs a Rootkit scan and requires a system restart. When you see a prompt to restart the computer, click Restart. If you do not want to include the Rootkit scan, go to Settings, and uncheck the option Include Rootkit scan (requires a computer restart).

  8. After the computer is restarted, the scan starts automatically. Follow the on-screen instructions.

    Wait for the scan to complete.
