Threat Details:

Categories:

Description:
This trojan horse pretends to be a Word document with information about the user being accused for filesharing. Once the file is being executed , it connects to the internet in background, downloads other trojan horses and sends information about the user to a malicious website when the user opens the Internet Explorer. Additionally the Firefox gets sabotaged and the Internet Explorer gets authorized for the Windows Firewall.
Supposed Functionality:
supposed to be an email with information in a Word document.
Removal Instructions:

Autorun:

You will have to use a global search for files without a name specified. Be extra careful, because just the name might not be enough to identify files!
