Hello.

I have problem with this trojan, it come with email attachment. Win 7 64bit

If computer boots then after few second some file(AppData/Local/Temp/xxxxxxxxxxxxx.reg) asks permission to change registry, if i press no then it ask again and cant use computer(open other programs, open task manager etc this windows is always active).  I can only use pc in safe mode.

AV is ESET and every boot it tells it deleted threat Java/Adwind.AUU trojan but really not, file still ask permission to change registry. Of course i dont want test what happens if i give it to permission :)

Scanned with ESET- nothing, Malwarebytes- nothing, ASWCleaner- found 2 threats(not this torjan), deleted, next scan nothing, RKill- nothing, MS Safety Scanner- nothing

Hi user742 :)

My name is Aura and I'll be assisting you with your malware issue. Since we'll be working together, you can call me Aura or Yoan, which is my real name, it's up to you! Now that we've broke the ice, I'll just ask you a few things during the time we'll be working together to clean your system and get it back to an operational state.
  • As you'll notice, the logs we are asking for here are quite lenghty, so it's normal for me to not reply exactly after you post them. This is because I need some time to analyse them and then act accordingly. However, I'll always reply within 24 hours, 48 hours at most if something unexpected happens
  • As long as I'm assisting you on BleepingComputer, in this thread, I'll ask you to not seek assistance anywhere else for any issue related to the system we are working on. If you have an issue, question, etc. about your computer, please ask it in this thread and I'll assist you
  • The same principle applies to any modifications you make to your system, I would like you to ask me before you do any manipulations that aren't in the instructions I posted. This is to ensure that we are operating in sync and I know exactly what's happening on your system
  • If you aren't sure about an instruction I'm giving you, ask me about it. This is to ensure that the clean-up process goes without any issue. I'll answer you and even give you more precise instructions/explanations if you need. There's no shame in asking questions here, better be safe than sorry!
  • If you don't reply to your thread within 3 days, I'll bump this thread to let you know that I'm waiting for you. If you don't reply after 5 days, it'll be closed. If you return after that period, you can send me a PM to get it unlocked and we'll continue where we left off
  • Since malware can work quickly, we want to get rid of them as fast as we can, before they make unknown changes to the system. This being said, I would appreciate if you could reply to this thread within 24 hours of me posting. This way, we'll have a good clean-up rhythm and the chances of complications will be reduced
  • I'm against any form of pirated, illegal and counterfeit software and material. So if you have any installed on your system, I'll ask you to uninstall them right now. You don't have to tell me if you indeed had some or not, I'll give you the benefit of the doubt. Plus, this would be against BleepingComputer's rules
  • In the end, you are the one asking for assistance here. So if you wish to go a different way during the clean-up, like format and reinstall Windows, you are free to do so. I would appreciate you to let me know about it first, and if you need, I can also assist you in the process
  • I would appreciate if you were to stay with me until the end, which means, until I declare your system clean. Just because your system isn't behaving weirdly anymore, or is running better than before, it doesn't mean that the infection is completely gone
    This being said, I have a full time job so sometimes it'll take longer for me to reply to you. Don't worry, you'll be my first priority as soon as I get home and have time to look at your thread
  • This being said, it's time to clean-up some malware, so let's get started, shall we? :)

    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. Read 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 You

    This is what Jesper M. Johansson, Security Program Manager at Microsoft TechNet has to say: Help: I Got Hacked. Now What Do I Do?.

    The only way to clean a compromised system is to flatten and rebuild. Thats 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).


    So you have two options here. The first one is that we go ahead with the clean-up, thought I cannot guarantee that your computer will be safe to use at the end. The second is a nuke and pave (format and reinstall of Windows). I can assist you with both option.
