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 trojan which deletes files on the C:\ drive via changes made to the autoexec.bat file. This trojan accomplishes its deletion using the program "deltree.exe" typically found on Win9x systems. Deltree does not exist by default on WinNT/2K/XP systems.

The initial file is named "MIRC PATCH.EXE" to pose as a necessary update to the mIRC program. When run, it reboots the system and as Windows restarts, all files on the C:\ drive will be deleted. The following message may appear:

synix.w32 ... infected.

Symptoms

Error message as 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, 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).
