Overview

This is a trojan detection. Unlike viruses, trojans do not self-replicate. They are spread manually, often under the premise that they are beneficial or wanted. The most common installation methods involve system or security exploitation, and unsuspecting users manually executing unknown programs. Distribution channels include email, malicious or hacked web pages, Internet Relay Chat (IRC), peer-to-peer networks, etc.

Characteristics

This is a remote access trojan.

When run, this trojan drops PCClient.dll to the windows directory, typically:

C:\Windows\PCClient.dll

Then it adds the following registry entry.

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
Policies\Explorer\Run system32 = (File path)

Then this trojan injects the dll in to the process of “IExplorer.exe”.

This dll attempts to query a remote DNS server with "7oo.meibu.com". Then it makes http connections to the site and sends hardware information including the computer name, CPU, memory status, and drive information. This trojan also waits for commands from the remote site.

Symptoms

• Unexpected http access to the site mentioned above
• Existence of the file and registry key mentioned above

Method of Infection

Trojans do not self-replicate. They are spread manually, often under the premise that the executable is something beneficial. Distribution channels include IRC, peer-to-peer networks, newsgroup postings, email, etc.

Removal

All Users:
Use current engine and DAT files for detection and removal.

Modifications made to the system Registry and/or INI files for the purposes of hooking system startup, will be successfully removed if cleaning with the recommended engine and DAT combination (or higher).

Additional Windows ME/XP removal considerations
