Troj/Dloader-JQ is a downloading Trojan for the Windows platform. 
Troj/Dloader-JQ copies itself to the file smiissm.exe in a subfolder of the 
Windows folder named "sys". This folder is created if it didn't exist 
previously. The Trojan ensures that it is run at login by creating the 
following registry entry: 
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
Microsoft Internet Explorer
"%WINDOWS%\sys\smiissm.exe" 
Troj/Dloader-JQ downloads a file from a preconfigured URL to the file Dados.exe 
in the Windows\sys\ folder and executes it. 
If run with sufficient rights the Trojan will install itself as an application 
authorised by Windows Firewall to communicate with the outside world. 

This IDE file also includes detection for:

Troj/LegMir-AA
