Hi there.

My PC is infected with the Win32/alureon.CT TrojanHorse (possibly some other malware now as well :S )

I have tried Spybot, Ad aware and Microsoft Security Essentials in normal and safe mode but AlureonCT is still being detected no matter how many times I remove it.

I noticed as well other malware popping up now as well.

Below is the log from Malwarebytes Anti malware and gmer

Hello and welcome,this one is ugly.

IMPORTANT NOTE: Win32/alureon is related to a nasty variant of the TDSSSERV rootkit component. Rootkits, backdoor Trojans, Botnets, and IRC Bots are very dangerous because they compromise system integrity by making changes that allow it to by used by the attacker for malicious purposes. Rootkits are used by Trojans to conceal its presence (hide from view) in order to prevent detection of an attacker's software and make removal more difficult. Many rootkits can hook into the Windows 32-bit kernel, and patch several APIs to hide new registry keys and files they install. They can disable your anti-virus and security tools to prevent detection and removal. Remote attackers use backdoors as a means of accessing and taking control of a computer that bypasses security mechanisms. This type of exploit allows them to steal sensitive information like passwords, personal and financial data which is send back to the hacker. To learn more about these types of infections, you can refer to:

What danger is presented by rootkits?
Rootkits and how to combat them
r00tkit Analysis: What Is A Rootkit

If your computer was used for online banking, has credit card information or other sensitive data on it, you should disconnect from the Internet until your system is cleaned. All passwords should be changed immediately to include those used for banking, email, eBay, paypal and online forums. You should consider them to be compromised and change each password using a clean computer, not the infected one. If not, an attacker may get the new passwords and transaction information. If using a router, you need to reset it with a strong logon/password so the malware cannot gain control before connect again. Banking and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?
What Should I Do If I've Become A Victim Of Identity Theft?
Identity Theft Victims Guide - What to do


Although the infection has been identified and may be removed, your PC has likely been compromised and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume the computer is secure even if the malware appears to have been removed. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired so you can never be sure that you have completely removed a rootkit. The malware may leave so many remnants behind that security tools cannot find them. Tools that claim to be able to remove rootkits cannot guarantee that all traces of it will be removed. Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat and reinstall the OS. Please read:

When should I re-format? How should I reinstall?
Help: I Got Hacked. Now What Do I Do?
Where to draw the line? When to recommend a format and reinstall?


Should you decide not to follow that advice, we will do our best to help clean the computer of any infections but we cannot guarantee it to be trustworthy or that the removal will be successful. Some infections are difficult to remove completely because of their morphing characteristics which allows the malware to regenerate itself. Sometimes there is another hidden piece of malware which has not been detected by your security tools that protects malicious files and registry keys (which have been detected) so they cannot be permanently deleted. Disinfection will probably require the use of more powerful tools than we recommend in this forum. Before that can be done you will need you to create and post a DDS/HijackThis log for further investigation. Let me know how you wish to proceed.
