Can someone explain me how to uninstall this anti-virus software?
To uninstall this software you can go to Start > Control Panel > Add\Remove programs (Windows XP) or Programs and Features (Windows 7), select the program that you want to remove and click Uninstall. Also you can use CCleaner or Revo Uninstaller to remove any program that is installed on your computer.
This does not work if you do not have the password.
