Some virus infected my system. I scanned the computer with norton antivirus couldn't remove it.

Here is the details , i copied from the Auto-Protest blocked theats popup window -> view details pages.  I read other post about the virus and still not sure how to remove this virus from my system.

 

I would like to know what is the proper way to  remove the virus.
