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.

Aliases

• Backdoor.IRC.mIRC-based (AVP)

• Win32.IRCFlood (CA)

Characteristics

This detection covers packed and renamed mIRC (an Internet Relay Chat application) instances. Many IRC trojans will distribute the mIRC program to allow the execution of mIRC script files.

Symptoms

Unexpected traffic on TCP port 6667.

Method of Infection

Varies. Typically this trojan is contained within a self-extracting archive along with other script based trojans.

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
