Name secure2.bat


Backdoor.IRC.Zcrew.C is a backdoor Trojan horse that may allow for the remote control of an infected system through IRC and FTP.
Allows unauthorized access to the infected machine.

When Backdoor.IRC.Zcrew.C is executed, it performs the following actions:
Creates the following files in the %System%\instsrv folder:
001.config; Configure; COPYING; cygregex.dll; cygwin1.dll; firedaemon.exe; foxdg.exe; hideapp.exe; ident.exe; inst.bat; iroffer.cron; KILL.EXE;
lrs.reg; Makefile.config; mybot.ignl; mybot.ignl.bkup; mybot.ignl.tmp; new.txt; README; rn.bat; secure1.bat; secure2.bat; startsecure.bat; test.bat; WHATSNEW

Creates the following nonmalicious files in the folder, %System%\instsrv\src:
admin.c; dccchat.c; defines.h; display.c; globals.h; headers.h; iroffer.c; iroffer.cron; misc.c; plugins.c; transfer.c; upload.c; utilities.c

Starts foxdg.exe, which is the Iroffer application, as a service process.

Manual removal:
Navigate to the key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
amd delete the value: "Bat"="C:\winnt\system32\instsrv\secure2.bat"

Also you must delete the nonmalicious files:
