current url being added to links

[eluser]bennyhill[/eluser]
In my source code (a product description from a database), I have a regular anchor tag

Code:

<a href="www.example.com">Example</a>

but when I mouse over the anchor in the browser I get the current url added to the beginning of the anchor such as

Code:

http://localhost/mysite/cat/106/www.example.com

As I stated above, it is a regular anchor tag that is in a product description coming from a database, I am not using the echo anchor() from the codeigniter library.

Does anyone know why this is happening?
