Summary
TrojanDropper:Win32/Ceekat.B is a member of the Win32/Ceekat family - a collection of trojans that steal information such as passwords for online games. Generally they can do this by reading information directly from running processes in memory. The processes each Ceekat variant targets are very specific, and may include any number of applications, not necessarily limited to online games.

Technical Information (Analysis)
TrojanDropper:Win32/Ceekat.B is a member of the Win32/Ceekat family - a collection of trojans that steal information such as passwords for online games. Generally they can do this by reading information directly from running processes in memory. The processes each Ceekat variant targets are very specific, and may include any number of applications, not necessarily limited to online games.
Installation
When executed, TrojanDropper:Win32/Ceekat.B copies itself as %Application Data%\dns.bak and tampers the MZ header, possibly in an effort to avoid detection.
The malware then drops and loads a DLL file into two different copies as:
%Application Data%\dns.sys
%Application Data%\dns.new
These files are detected as PWS:Win32/Ceekat.gen!A.
Note: %Application Data% refers to a variable location that is determined by the malware by querying the Operating System. The default installation location for the Application Data folder for Windows 2000 and NT is C:\Documents and Settings\<user>\Application Data; and for XP, Vista, and 7 is C:\Users\<user>\AppData\Roaming.
Payload
Terminates processes
TrojanDropper:Win32/Ceekat.B attempts to terminate the process "qq.exe".

Prevention
Take the following steps to help prevent infection on your computer:
Enable a firewall on your computer.
Get the latest computer updates for all your installed software.
Use up-to-date antivirus software.
Limit user privileges on the computer.
Use caution when opening attachments and accepting file transfers.
Use caution when clicking on links to Web pages.
Avoid downloading pirated software.
Protect yourself against social engineering attacks.
Use strong passwords.
Enable a firewall on your computer
Use a third-party firewall product or turn on the Microsoft Windows Internet Connection Firewall.

Get the latest computer updates
Updates help protect your computer from viruses, worms, and other threats as they are discovered. It is important to install updates for all the software that is installed in your computer. These are usually available from vendor Web sites.
You can use the Automatic Updates feature in Windows to automatically download future Microsoft security updates while your computer is on and connected to the Internet.

Use up-to-date antivirus software
Most antivirus software can detect and prevent infection by known malicious software. To help protect you from infection, you should always run antivirus software, such as Microsoft Security Essentials, that is updated with the latest signature files. For more information, see
http://www.microsoft.com/security/antivirus/av.aspx.Limit user privileges on the computer
Starting with Windows Vista and Windows 7, Microsoft introduced User Account Control (UAC), which, when enabled, allowed users to run with least user privileges. This scenario limits the possibility of attacks by malware and other threats that require administrative privileges to run.
You can configure UAC in your computer to meet your preferences:

Use caution when opening attachments and accepting file transfers
Exercise caution with e-mail and attachments received from unknown sources, or received unexpectedly from known sources. Use extreme caution when accepting file transfers from known or unknown sources.
Use caution when clicking on links to Web pages
Exercise caution with links to Web pages that you receive from unknown sources, especially if the links are to a Web page that you are not familiar with, unsure of the destination of, or suspicious of. Malicious software may be installed in your computer simply by visiting a Web page with harmful content.
Avoid downloading pirated software
Threats may also be bundled with software and files that are available for download on various torrent sites. Downloading "cracked" or "pirated" software from these sites carries not only the risk of being infected with malware, but is also illegal. For more information, see 'The risks of obtaining and using pirated software'.
Protect yourself from social engineering attacks
While attackers may attempt to exploit vulnerabilities in hardware or software to compromise a computer, they also attempt to exploit vulnerabilities in human behavior to do the same. When an attacker attempts to take advantage of human behavior to persuade the affected user to perform an action of the attacker's choice, it is known as 'social engineering'. Essentially, social engineering is an attack against the human interface of the targeted computer. For more information, see 'What is social engineering?'.
Use strong passwords
Attackers may try to gain access to your Windows account by guessing your password. It is therefore important that you use a strong password – one that cannot be easily guessed by an attacker. A strong password is one that has at least eight characters, and combines letters, numbers, and symbols. For more information, see
