UAC Bypass ‑ Trusted Folder Abuse (WID 4688: credwiz.exe)
The computer seems to be infected with a virus.
The
UAC bypass through Trusted Folder abuse
is a method for tricking Windows into running programs with
Administrator permissions, by using a blank-terminated
Windows \System32 folder.
The program doing it is named credwiz.exe. The name is legit,
but the program may not be the one that is part of Windows.
