How do I get rid of these porn links that keep coming back in my favorites?

Some sites, not always but often pornography related, are notorious for using all sorts of underhanded techniques to put their advertising on your computer and in your face. Hijacking your favorites or bookmarks is definitely one of those techniques.

My first recommendation is to run a spyware scanning program such as Spybot Search and Destroy or AdAware. What happens is some site or software will install software on your machine that periodically puts things in your favorites list or makes other changes without your knowledge. The spyware scanners look for various known offenders and remove them.

The second recommendation would be to watch what you install. What may seem like a helpful toolbar, or handy utility may occasionally include spyware as additional payload. In fact, you may have even agreed to the spyware when you accepted a license agreement! The only toolbar I recommend is Google's. There are several others out there, some of which are good, others of which are known to be very invasive and big offenders.

Finally, I've caught myself a time or two inadvertently adding things to my favorites without even realizing it. CTRL+D in my email program means "delete" so I'm in the habit of using it when I've finished reading an email. In IE however, CTRL+D is a shortcut to "add to favorites" which adds the current page to your favorites list. After reading a web page it's an easy mistake to make.
