Have you had problems with sites hijacking your Home Page or other Internet Explorer restrictions?
IE Restrictions will remove most common restrictions that may have been set by a sleaze web site as well as other methods.
I do not guarantee this will remove all types available as there are just too many to put in one program but this will take care of 24 of the most common ones.
Of course you can also use it to set any restrictions you'd like to have on your PC. |
