This has happened before. I'm surfing the net blindly, going from link to link, when suddenly I have a website where a window pops up that says: do you want make (name) your homepage?

You click "no", and it doesn't matter, it's now your home page and you can't get rid of it. This wouldn't be bad if the homepage wasn't pornographic, which it is in most cases.

I was told to just disconnect from the net and restart the computer.
I did this the last time it happened, but this pornagraphic site is still my homepage. It stops me from using any other search engine by making it an illegal function, which shuts my computer down. There are also vaguely pornographic pop up ads. It also adds porn sites to my list of favorites. I can temporarily make another site my homepage, but it only works until I turn disconnect from the internet.

Is there a way to fix this without taking the computer to a repair shop?

If there is, please talk down to me as if I knew next to nothing about computers, because I don't

Thanks, Steve
