I am now seeing that ISPs across the world is using an application named streamride for their some purpose.
And the customers of these ISPs are seeing ads on every page they pull from internet.
I faced the same issue and found a possible solution(what we can do from our end), from the site i specified, to prevent this ad from appearing.
I want people to know about this. There are users who think its some malware in their system and wastes time to find them out , and they even does a format of their disk.
