Ad Block messing up code

I recently installed Word Press for my blog. I use Firefox and I used to have the extension Ad Block for Firefox. I have since uninstalled the extension from my system. Well,I have noticed the following problem in Word Press when I try to link images within my pages. The following is an example of my code that is what happens when I link images in my Word Press pages. If it looks weird here go to my site and I have an entry showing the code. I am just trying to figure out what is going on.

<!-- BEGIN Ad Blocker //--> <script language="javascript"> <!-- var nstm_nsi_51; function nsic_nsi_51() { document.nsi_51.src="http://tigerwhispers.com:80/blog/fl/firefox.png/adokay/"; } //--> </script> <img src="http://127.0.0.1:1030/gif.cgi?cx=58&cy=58&txt=Firefox+Fan+Listing" name="nsi_51" border="0" height="58" width="58" /> <!-- END Ad Blocker //-->

This is what I want my code to look like.

Does anyone know why this is occuring?
