Heavy correlation of Mumu infections with infections of the Valla virus have been observed. It is suspected that Mumu caused a resurgence in Valla infections after Valla infected one of the .exe files included in the Mumu package. Previous to this, Valla was considered obsolete. It now ranks among the most-reported viruses on the WildList.
