i would suggest trying to restore your pc / laptop to a date before you added the files / started to have problems
all though this will not remove the files from the FS folder it may undo any changes you have made to any system files / settings thus allowing you to boot windows properly again
i doubt very much that this problem was caused by FS.
as i said give system restore a try and let us know how you get on
