Fix problems downloading Norton Power Eraser

For Norton Power Eraser to run, you need to have the Internet access. An incorrect DNS setting or Windows host file setting can block the Internet access on your computer. Check whether you can restore the Internet access on your computer by fixing the proxy settings, DNS settings, or Windows host file settings.

STEP 1

Check proxy settings

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

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

    inetcpl.cpl

  3. In the Internet Properties window, on the Connections tab, click LAN Settings.

  4. Do one of the following:

    • If you do not use any proxy servers, or if you don't know about proxy servers, make sure that the Use a proxy server for your LAN option is unchecked.

    • If you use a proxy server, make sure that the settings are correct.

  5. Click OK.

  6. In the Internet Options window, click Apply and then click OK.

STEP 2

Check for incorrect DNS settings

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

    control

  3. Click the Network and Internet icon, and then click Network and Sharing Center. In the left pane, click Change adapter settings.

  7. In the Internet Protocol (TCP/IP) Properties window, on the General tab, check the DNS server settings.

    • If Use the following DNS server addresses radio button is selected, check the server addresses. Make sure that the DNS server addresses displayed are the same that are provided to you by your Internet service provider or your network administrator.

    • If the DNS server address starts with 85.255.11x.x, then it is more likely that the DNS cache has been poisoned as the result of a Pharming attack.
