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

When executed this trojan modifies the Internet Explorer search page settings to: http://www.i--search.com/ie/

Upon execution the following registry entries are made:

• HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main "Search Page" = "http://www.i--search.com/ie/"

A file called pcsearch.reg is dropped into c:\Windows and run at everystartup:

• HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run "SysSearch" = "REGEDIT.EXE -s C:/WINDOWS/pcsearch.reg"

This means that if you try to remove this new Search Page manually within Internet Explorer, this trojan will constantly re-open it after you re-start the PC.

Please note that pcsearch.reg is already detected as Reg/Seeker trojan.

Symptoms

• Internet Explorer Search Page changed to http://www.i--search.com/ie/
• Presence of pcsearch.reg on the system.

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

AVERT recommends to always use latest DATs and engine. This threat will be cleaned if you have this combination.
