Troj/Dermon-G is a password stealing Trojan for the Windows platform.

When first run Troj/Dermon-G copies itself to <System>\abrada.exe and creates the following files:

<System>\abrada.dll
<System>\abradaload.dll

<System>\abrada.dll is a remote notification DLL component which sends stolen information to a remote website.

<System>\abradaload.dll is a process injector DLL component which will attempt to inject itself into other processes in order to stealth itself.

Troj/Dermon-G also attempts to create the following files:

<System>\abrada.ini
<System>\abrada.dat

These files may be deleted.
