After all that cleaning my computer from spyware I realized the following codes were showing up constantly (everywhere I go) when I viewed a page source.
Just before </head> ends
HTML
<script language='javascript' src='http://127.0.0.1:****/js.cgi?pca&r=*****'></script>
And after </html>
HTML
<script language='javascript'>postamble();</script>
WHAT DA HECK IS IT??
It looks like some java script was calling from within my computer and *'s were changing constantly with each time I refreshed a webpage for a source code.
After few hours of searching, I found a possible answer. It seems like if you have firewall programs such as Zone Alarm Security or Check Point Integrity (which I have) these programs insert the above codes automatically for every web page you view.
I turned off my firewall, refreshed a webpage and viewed the source code again and this time it did not show.
We can all relex now, whew~ I thought something was still present in my computer. Just sharing this information if you ever wondered about these codes.
