Troj/Agent-II is a Trojan for the Windows platform.

Troj/Agent-II runs continuously in the background, providing a backdoor server which allows a remote intruder to gain access and control over the computer via IRC channels.

When first run Troj/Agent-II copies itself to &ltSystem&gt\l074.exe and creates the following files:

&ltSystem&gt\msdirectx.sys
\xz.bat

The file xz.bat is detected as Troj/KillProc-A and the file msdirectx.sys is detected as Troj/NtRootK-F.
