i noticed my r4 was not working so i plug it into my computer and i saw these random folder and icons the icon name was random shapes and they will not delete. now my r4 will get to the menu i will click the game icon and then it freezes and it does not show any games nor any menu options like the cheates or anything .
the last thing is that my moonshel is gone and some of options. did the random folders infect the other ones???????

does any body suggest anything????
