Arrival, Installation and Autostart Technique
This file infector may be downloaded unknowingly by a user when visiting malicious Web sites.
It creates the following registry entry to bypass the Windows Firewall:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\
SharedAccess\Parameters\FirewallPolicy\StandardProfile\
AuthorizedApplications\List
\??\%System%\winlogon.exe = "\??\%System%\winlogon.exe:*:enabled:@shell32.dll,-1"

File Infection

It hooks the following APIs so that when any of these APIs are called, it proceeds to its infection routine:

• NtCreateFile
• NtOpenFile
• NtOpenProcess
• NtCreateProcessEx

This file infector infects by appending its code to target host files. It infects files of the following types:

• .EXE
• .SCR

It does not infect files that contain the following strings in their file names:

• WC32
• WCUN
• WINC

Backdoor Capabilities
It searches for the Winlogon process by enumerating the running processes and injects a thread that is responsible for its backdoor routines.


It connects to the following IRC server irc.zief.pl and waits for a command from a remote user. Using this connection, it downloads TROJ_INJECTOR.AR from the following URL:

• http://goasi.cn/ex/a.php

Actually on second thought you may want to do System restore to a point before you picked up the file infector Malware. Apparently It is causing significant registry/Windows corruption that may be difficult to repair. Did you allow it past UAC? That should have contained it in the IE7 sandbox.

Assumming for a moment it is still In the IE temp files, delete all files/cookies, etc.
