1. Ensure no other anti-virus software is installed.

   For the best results there should be no anti-virus applications installed in addition to McAfee Anti-virus. Begin by checking for and removing any extraneous anti-virus software.

   • If you're not sure if you have another piece of anti-virus software installed check your taskbar for anti-virus icons.

     • 

       The 'M' icon on the far left can indicate McAfee Anti-virus is already installed.

     • 

       The 'diagonal shield' icon on the far right shows Symantec Anti-virus is installed, this anti-virus system should be uninstalled before proceeding.

     • 

       This 'V Shield' icon shows a version of McAfee Anti-virus is installed, this anti-virus system will be uninstalled automatically.

   • If you know you have other anti-virus software installed, please use add/remove programs and uninstall it.

   • In a few exceptional cases as a last resort it will be necessary to use NoNav or McAfee Consumer Products Removal Tool to completely uninstall remaining anti-virus components.
