Hi Starlite :)

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 Malwarebytes Forums, 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 Malwarebytes Forums'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? :)

What makes you think that your computer is infected? What symptoms/issues are you experiencing?

Hi Aura, 

Symptoms: As of two days ago, I was locked out of my computer. It would not let me login under my account or the administrator account. I researched followed advice ran spyware malware programs the whole day. The next morning, yesterday, the computer had a different promising t and account. I cannot access any programs or files including wifi. It would not allow a windows reinstall, recovery fix, windows cleaner is blocked. I can access the internet by using Ethernet and an Amazon app that had appeared.  It is only accessing Windows/System32 folders. I cannot use the windows tab key and for most of yesterday the pc would have audit.exe appear. I kept closing it in the task menu. Today it did not reappear in the task manager. The virus has renamed my computer. Only the administrator account was available until today. I can see a public account but not my original. I had something similar happen at work years ago.

There is a lot going on. But none of what I need.

What's the name of the other account that showed up?

I need more details. What happens when you try to open your programs, or connect to a WiFi network?

It would not allow a windows reinstall, recovery fix, windows cleaner is blocked.

How did you try to reinstall Windows? And by Windows Cleaner, do you mean cleanmgr.exe?

The virus has renamed my computer.

What was your computer's previous name?

I did not write the name down it began with a rdu or rjd. 

I used the system recovery option F10. Chose the save files option. Then let it do whatever it need to do. It failed and gave an error message. I then tried to reinstall windows 10 by downloading it directly from Microsoft and reinstalling it.  The virus would not allow it to complete.  

I used Microsoft Windows Cleaning tool it did not work because the virus will not let it open. 

All my files and documents are gone. I still have some programs associated with them when I open the x86 folder. 

Nothing happens when I try to open the programs. I can only right click and open as an administrator.  The programs that will work were there. 

I am a contractor and cannot work  or get my next job without my computer. I need urgent help,

Hi Aura, 

The audit.exe just show up at booting the computer. It is in the system32/audit.exe folder. I can close it in task manager once I manage to go online. If I close it before that step it restarts my computer. I saw several recent examples of on the support site as Trojans. I also downloaded ccleaner and Spyhunter on Friday or Saturday to clear some old files. I saw the story the news story on CCleaner. I also saw a story on the System32 Trojan. 

What do I need to do?

These are all legitimate executables, none of them are malicious.

Right now, I don't see any signs of infection on your machine, so your issue(s) are probably caused by something else.

I then tried to reinstall windows 10 by downloading it directly from Microsoft and reinstalling it.  The virus would not allow it to complete.  

What error did you get when trying to do that, and at what step of the process did it fail?

Are you trying to do a clean installation (format your hard drive, and install Windows on it)? If so, there should be no reason for it to fail.

Did you use the Windows 10 Media Creation Tool? Also, are you using a CD, DVD or USB to install Windows 10?
