I've got this problem where my IE option --> General--> Homepage is disabled. The homepage becomes some stupid porn ad, and I was unable to change the homepage in the internet option simply because the homepage box is disable where I am unable to type anything. And my question is how to how to make the homepage avaliable for me to change homepage address.
Thanks
