In this article: http://oraclebiblog.blogspot.com/2009/07/how-to-hide-saved-filter-view-link.html John Andrzejek shows a way of doing this by editing a CSS file.
I prefer editing the viewmessages.xml.
Remove the text between the kmsgViewSavedFilterAnchorText tags. (you have to do this for every languages you use).
Till Next Time
