Trojan.Win32.KillAV.s or KillAV.s is a trojan on Microsoft Windows that is part of a large family called KillAV. This one, unlike the other trojans in the KillAV family, does not actually kill Antivirus software.


Once launched the trojan will create a massive file with a length of a single byte in the form of setup.img in the C:\ Drive. The trojan will then try to delete every executable on the hard-drive.
