I called in and further asked them to investigate this usual problem.
What we found out, is that the my modem is suffering from a huge packet lost, without even being connected to my computer. So that ruled out the warez problem, glad I didn't format it then found out I didn't need to..
Another good thing is that... 40% of the modems in my area is suffering from the same problem. So I guess its not a throttled after all... A ticket been issued to see why there is such a huge packet lost happening in the area.
