More Information
Troj/Agent-BJ is a Trojan for the Windows platform.
Troj/Agent-BJ copies itself to the Windows system folder using the name clfmon.exe and drops a DLL file to the same folder called syspack.dll. These files may be hidden from view.
Troj/Agent-BJ sets the following registry entry to run itself automatically on log-on:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
clfmon.exe
clfmon.exe
This registry entry may also be hidden from view while the Trojan is running.
Troj/Agent-BJ also creates a number of registry entries under the main registry entry:
HKLM\Software\Microsoft\Windows\CurrentVersion\Ms4Hd\
The files and registry entries will become visible once the Trojan is no longer running on the computer.
