C:\WINDOWS\system32\lsass.exe is op zich een legitiem windows proces, wat internet verbinding voor diverse andere programma's verzorgt.

Het virus heet over het algemeen issas.exe (je hebt ook virus dat lsass.exe heet als ik de resultaten van google zo bekijk) en het legitieme proces lssas.exe, maar omdat de naam van het virus met een hoofdletter I in taakbeheer staat zijn ze niet uit elkaar te houden. De hoofdletter I en de kleine letter l zijn namelijk hetzelfde in het lettertype wat taakbeheer gebruikt.
