If the installation script of Avira Antivirus Premium, Avira Internet Security or Avira Professional Security reports that the installation of LSP (Layered Service Provider) failed, LSP has to be reset. This may happen if Web Protection or Mail Protection are installed along with another LSP-based program on the same computer.


Note
These instructions are not suitable for Windows 8.
It may be possible that some software is not working anymore after you have reset the LSP.
Make sure to log on as an administrator, if you have not already done so.



To reset the LSP on Windows XP:

  1. Go to StartRun
  2. Type cmd and press Enter, to open the command prompt
  3. Type the following command:

    netsh winsock reset

  4. Press Enter
  5. Restart the computer


To reset the LSP on Windows Vista/ Windows 7:

  1. Go to StartProgramsAccessories
  2. Right-click Command Prompt and select Run as administrator
  3. Type the following command:

    netsh winsock reset

  4. Press Enter
  5. Restart the computer

After the restart, you can continue installing Avira Antivirus Premium, Avira Internet Security or Avira Professional Security.


Please perform a change installation:

  1. Open the Windows control panel
    Windows XP / 2000: StartSettingsControl PanelAdd or Remove Programs
    Windows Vista / 7: StartControl PanelProgramsPrograms and Features


  2. Select the Avira application (e.g. Avira Internet Security) and click on Change

    Avira Internet Security change installation
     
  3. Select Modify and click Next

    ISEC12_change installation modify
     
  4. Confirm all the following dialogs with Next as well

  5. Restart your computer

Please keep in mind that this problem may remain if LSP-based programs are still installed on the system, since they can repair themselves, i.e. renew their entry in the LSP-stack.
