Have a problem with favourites on Internet Explorer. Some websites keep automatically adding to my Favourites list. I delete them every time, but when i turn my computer on again, they keep reappearing. How do I stop them doing this?

Take this to a security thread and we will see if this is a case of spyware chances are it is. So take it there.

Amen to that. You've got a spyware/security problem for sure, and it'd be best dealt with by following the suggestions made here:

and then posting about any remaining problems in the 'Security' forum section.
