Hi every one,
Two day ago i found a chineese pop up that comes out every visit to any website.
I activated the popup blocker with a high security and disabled the windows messenger Add-Ons, deleted cookies and offline files.
It prevented it from poping up again.
I need to know if my procedures are right, and what is this popup?
Thank you.

They are fine to do what you did.

As to what is the pop up...well you have it on your system and you are the only one that can tell what it is.

use your anti virus and anti spyware programs to see if it can be removed.
