i bougtht two of these devices from dealextrenme and both had viruses on them.
can you check on the player via the file manager and see if you have any files like autorun.ini and ravmon.exe and also the one i received was not the same as the ones in the pic, if your has screws holding the case together then yours are different too.

BTW - the yellow lie in the player hides the file name but it is "autorun.ini"
just a heads up
not if you have not got your system set up to "view hidded files and folders" then you will not see the files when it is connected to the computer, you will need to look on the player itself
beside one of the units fell apart, buttons fell of and i only had them for 2 hours before i opacked them up and sent them back.
i thought these were seriously bad quality, even for the price
