Tell me what logs and stuff I'll need to resolve this issue. 

:welcome:

 

Let's try this first.

Let us get a clean install of the current version.

We have another tool called MB-Clean which will automate the whole process for you.

 Tool can be found at https://downloads.malwarebytes.com/file/mb_clean

1. After downloading the tool run the tool.

2. The tool will automatically clean up the older possibly damaged installation and will ask you for a restart.

3. Restart your system and then the MB-Clean tool will prompt you to re-install the latest product .

4. Click on "Yes" to reinstall MB 3.×.

5. Now you will have the latest product installed.

Please let me know if you are still seeing issues after the latest product install.

Sadly, it didn't work.

Let's move on to the Diagnostic part of this

  1. Create and obtain Farbar Recovery Scan Tool (FRST) logs
  1. Download FRST and save it to your desktop
    NOTE: You need to run the version compatible with your system. You can check here if you're not sure if your computer is 32-bit or 64-bit
  2. Double-click to run FRST and when the tool opens click "Yes" to the disclaimer
  3. Press the "Scan" button
  4. This will produce two files in the same location (directory) as FRST: FRST.txt and Addition.txt
    NOTE:
    These two files will be collected by the MB-Check Tool and added to the zip file for you
  1. Create and obtain an mb-check log
  1. Download MB-Check and save to your desktop
  2. Double-click to run MB-Check and within a few second the command window will open, then click "OK"
  3. This will produce one log file on your desktop: mb-check-results.zip
  4. Attach this file to your forum post by clicking on the "Drag files here to attach, or choose files..." or simply drag the file to the attachment area

Hi narutog7 :)

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? :)

Please give me a few to review your logs and get back at you.

Thank you for waiting. If I were you, I would uninstall Ace Stream Media 3.1.16.1 and its extension in all your web browsers, as it comes with an adware module that is enabled after a certain period of time.

After running the FRST fix below, a .zip file called DATE-TIME.zip (DATE and TIME being the date and time on which the fix was ran) will be on your desktop. Upload it to the link below.

Follow the instructions below to execute a fix on your system using FRST, and provide the log in your next reply.

  • Download the attached fixlist.txt file, and save it on your Desktop (or wherever your FRST.exe/FRST64.exe executable is located)
  • Right-click on the FRST executable and select Spcusrh.pngRun as Administrator (for Windows Vista, 7, 8, 8.1 and 10 users)
  • Click on the Fix button

  • On completion, a message will come up saying that the fix has been completed and it'll open a log in Notepad
  • Copy and paste its content in your next reply

It looks like you were infected with XRat (Xtreme Rat).

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:


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).

I cannot guarantee at 100% that your system will be clean after the removal. It could have been compromised in a way that would make it impossible for me to see it the logs. Therefore you have two options: continue with the clean-up, or do a nuke and pave (format and reinstall). The choice is yours.

Alright. Now you should be able to install and run a scan with Malwarebytes.

j1Bynr2.pngMalwarebytes - Clean Mode

  • Download and install the free version of Malwarebytes
    Note: If you have Malwarebytes already installed, you don't need to install it again. Simply start from the next bullet point
  • Once Malwarebytes is installed, launch it and let it update his database. You might have to click on the little arrow by Scan Status in the middle right pane for it to do so
  • Once the database update is complete, click on the Scan tab, then select the Threat Scan button and click on Start Scan
  • Let the scan run, the time required to complete the scan depends of your system and computer specs
  • Once the scan is complete, make sure that the first checkbox at the top is checked (which will automatically check every detected item), then click on the Quarantine Selected button
    • If it asks you to restart your computer to complete the removal, do so
  • Click on Export Summary after the deletion (in the bottom-left corner) and select Copy to Clipboard. Paste the content in your next reply

Alright. Run a new scan with FRST and attach the new set of logs (FRST.txt and Addition.txt). I'll just make sure that the main XRat infection is gone and bot preventing Malwarebytes from being installed

You need to run FRST with this fixlist (like you did with the first one). So download it, move it in the same folder as FRST (it should be on the desktop), launch FRST and use the Fix button. Once done, attach the fixlog.txt that will be on your desktop.
