Well, straight to the point.
At first, I can't copy/paste/move/rename folders (only folders, any other filetype is fne). Then, everytime I logged in I get a couple of messages like "xxx has stopped working" (the xxx themselves are google installer, rundll, and whatnot). Now, I can't play mp3 on my windows media player, and sometimes my WMP would crash whenever I play anything at it.
Any kind of help would be appreciated.
