Norton from Symantec

Error: "3048,3" appears on my Norton product

These steps are for the current version of the Norton products. If you have an older version or if you do not know your product version, go to Norton Update Center.


Restart your computer

  1. Exit all programs.

  2. Restart your computer.


Run LiveUpdate

  1. Start your Norton product.

  2. In the main window, click Security, and then click LiveUpdate.

  3. When Norton LiveUpdate is finished, click OK.

  4. Run LiveUpdate until you see the message, "Your Norton product has the latest protection updates."

  5. Exit all the programs, and restart the computer.


Update your virus definitions

  1. Go to the Intelligent Updater downloads page.

  2. Depending on your version of Windows, do one of the following:

    • For Windows (32-bit): Click the first file in the list under Filename. The file name starts with the year and ends with v5i32.exe. e.g. 20070828-017-v5i32.exe

    • For Windows (64-bit): Go to the 64-bit Platforms section, and click the first file in the list under Filename. The file name starts with the year and ends with v5i64.exe. e.g. 20090922-017-v5i64.exe

  3. Save the file to the Windows desktop.

  4. On the desktop, double-click the file that you saved.

  5. Follow the on-screen instructions to install the virus definitions using Intelligent Updater.

    If the problem persists, then your computer may be infected. We recommend that you download and run Norton Power Eraser to check if your computer is infected by a threat. Go to Step 4.


Download and run Norton Power Eraser

  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. Wait for the scan to complete.

  9. Exit all the programs, and restart your computer.

What if this didn't work?

Thank you!

Thank you for using Norton Support.
