Just a thought, but appears to be files that you are reloading back on each time, could be virus/trojan riding a double extended file, do a search/find for *.exe, look down the list of files and see if one or more are double extended.Then do the same for *.mp3, then *.jpg etc.  Mp3's come to mind, but not them necessarily.
Also you might try a very deep trojan scanner program like ANTS, it found a trojan for me that all others had missed for 2 yrs. I deliberately moved the trojan to a new folder and it found it again.
Just some thoughts.
