Troj/Agent-GZK attempts to edit websites to promote a target website.
Troj/Agent-GZK consists of three components:
<System>\jdk-1_5_0_19-windows-i391-pp\jav.bat
<System>\jdk-1_5_0_19-windows-i391-pp\js.exe
<System>\jdk-1_5_0_19-windows-i391-pp\dc.class
The files js.exe and dc.class are both detected as Troj/Agent-GZK.
Troj/Agent-GZK installs itself in the registry so it autoruns at startup with the following registry entries:
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
"Java (VM) v6.9"
"C:\WINDOWS\System32\jdk-1_5_0_19-windows-i391-pp\jav.bat"
