ChicaPC-fix finds and fixes all of the errors it finds. Some programs re-create the same invalid entries that were removed in the first scan. ChicaPC-fix will find them and remove them again from your system. There is no need to be worried, as a small number of errors may reappear after being removed by ChicaPC-fix. To get a rid of the errors permanently, you will need to find the program that is re-creating them.
