pplive关闭的 when I do not use it. I find a pxx.exe related to PPLive task under Task Manager runing all the time. I shut it down and disableed my network card last night. Lets see what will happen today!
I think I found out the problem. It was PPSAP.exe. Even my PPstream (I was wrong, I use PPStream not PPlive) is not open, that program keeps uploading a .pgf file created by PPStream from my pc. I shut it down from Task Manager and changed the setting in PPstream.
