Error: "3040,40018" appears on Norton Security Suite or Norton Business Suite

The error happens if you already have a non-Symantec security product on your computer. Symantec recommends that you run only one antivirus or antispyware product. Running only Norton Security Suite or Norton Business Suite provides the best protection and minimizes conflicts between security programs. We suggest that you uninstall any non-Symantec security product from your computer. For instructions to remove a non-Symantec security program from your computer, read the program documentation or contact the program manufacturer.

If you do not have a non-Symantec security product or if the problem persists even after uninstalling the non-Symantec security product, go to Step 1.

STEP 1

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.

STEP 2

Enable Auto-Protect at startup

  1. Start your Norton product.

  2. Click Settings.

  3. Under Detailed Settings, click Antivirus.

  4. On the Automatic Protection tab, if the Boot Time Protection shows Off, move the slider towards middle to Normal.

  5. Under Real Time Protection, if Auto-Protect shows Off, click the status indicator to turn it On.

Run a full system scan

    • If a virus is detected, write down the name and location, and then try to repair it. If it still cannot be repaired, try to quarantine or delete it. (If the file is one that you need, you may have to reinstall it later.) Go on to line 5.

    • If a worm, Trojan, or security risk is detected, write down the name and location, and then try to quarantine or delete it.

  4. Do one of the following:

    • If you were able to quarantine or delete a virus, worm. Trojan, or security risk, you are done. Restart the computer in normal mode. Follow the steps under STEP 5 to restart the computer in normal mode.
