Hi
IMPORTANT NOTE: One or more of the identified infections is a
backdoor Trojan.
Backdoor Trojans,
Botnets, and
IRCBots are
very dangerous because they
compromise system integrity by making changes that allow it to be used by the attacker for malicious purposes.
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 then sent back to the hacker.

Danger: Remote Access Trojans.
You should disconnect the computer from the Internet and from any networked computers until it is cleaned. If your computer was used for online banking, paying bills, has credit card information or other sensitive data on it,
all passwords should be changed immediately to include those used for taxes, email, eBay, paypal and any other online activities.
You should
consider them to be compromised and change passwords from a clean computer, not the infected one. If not, an attacker may get the new passwords and transaction information.
Banking and credit card institutions should be notified immediately of the possible security breach. Failure to notify your financial institution and local law enforcement can result in
refusal to reimburse funds lost due to fraud or similar criminal activity.
If using a
router, you need to reset it with a strong logon/password before connecting again.
Although the infection has been identified and may be removed, your machine 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 successfully cleaned or repaired. The malware may leave so many remnants behind that security tools cannot find them.
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:
Whenever a system has been compromised by a backdoor payload, it is impossible to know if or how much the backdoor has been used to affect your system...There are only a few ways to return a compromised system to a confident security configuration. These include:
• Reimaging the system
• Restoring the entire system using a full system backup from before the backdoor infection
• Reformatting and reinstalling the system
Backdoors and What They Mean to YouThis is what
Jesper M. Johansson, Security Program Manager at Microsoft TechNet has to say:
The only way to clean a compromised system is to flatten and rebuild. That’s right. If you have a system that has been completely compromised, the only thing you can do is to flatten the system (reformat the system disk) and rebuild it from scratch (reinstall Windows and your applications).
Help: I Got Hacked. Now What Do I Do?.
We will do our best to clean the computer of any infections seen on the log. However, because of the nature of this Trojan, I cannot offer a total
guarantee that there are no remnants left in the system, or that the computer will be trustworthy.
Many security experts believe that once infected with this type of Trojan, the best course of action is to reformat and reinstall the Operating System.
Making this decision is based on what the computer is used for, and what information can be accessed from it.
Knowing the above, do you wish to proceed with cleaning the malware from the computer?
