Summary of the findings:

What's been found	Severity Level
Uses the AppInit_DLLs value in order to install a module that will be loaded into the address space of every running application.
Packed with a packer that is known to be used by malware (e.g. to complicate threat analysis or detection).
Contains characteristics of an identified security risk.

Technical Details:

Possible Security Risk

Attention! Characteristics of the following security risks were identified in the system:

Security Risk	Description
Trojan-PWS.OnlineGames.ADRD	Trojan-PWS.OnlineGames.ADRD monitors the infected computer to steal password and other confidential information.
Hacktool.Rootkit!sd6	Hacktool.Rootkit!sd6 is a malicious application that could be used by attackers to break into a system.
Rootkit.Order	Rootkit.Order hides files with filenames containing the word "order" in them. It also tries to contact a remote server. The threat is known to target financial institutions by stealing sensitive information.

Attention! The following threat categories were identified:

Threat Category	Description
	A malicious trojan horse or bot that may represent security risk for the compromised system and/or its network environment
	A hacktool that could be used by attackers to break into a system
	A keylogger program that can capture all user keystrokes (including confidential details such username, password, credit card number, etc.)
