Remove Adware.StartPage (Uninstall Guide)

Tell your friends:
Adware.StartPage pretends to be a valid program but actually it is an adware that modifies the Internet Explorer home page without the user's permission. This adware changes certain Windows registry values so that it starts automatically when the user logins to Windows. It may modify Windows Hosts file and add a list of URLs to the Favorites folder, some of which may contain adult content as well. Basically, Adware.StartPage is designed to deliver various advertisements to the users' systems. I'm sure you know how to change the home page in Internet Explorer. Unfortunately, Adware.StartPage changes Internet Explorer's behavior, so you won't be able to change your home page through Internet Explorer settings as you would normally do. To remove Adware.StartPage from your computer, please follow the removal instructions below.
