Files put on desktop

Files nativelog game and runtime are put on desktop and when I open Minecraft it says downloading game unpacking and that type of stuff. File nativelog is the launcher info. File Game has java in it. File runtime has file jre-x64 which has file 1.8.0_25 in it which has java info in it. Can still play Minecraft fine. THE AFFECTED VERSION IS 1.8.1 BUT THE AFFECTED VERSION SELECTER DOES NOT HAVE IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
