I have a virus on our Windows Server 2008 Member server.  The Malwarebytes free version found pup.hacktool.bruteforce and removed it. Overnight the virus came back.  The obvious symptoms of the virus is that it creates local Administrator accounts and creates a folder in windows folder named tanechka.  It also runs a process named System_Minerd.exe, svchosl.exe and System Idle Process.  One of them will be running at 100%.  The system idle process is not the standard Windows Idle process.  I have deleted the user accounts and the folder and changed the RDC port.  We purchased the Pro version of Malwarebytes and it does not find the reinfected virus. 

 

I saw another closed post about the same issue "Server 2008 R2 SP1 system_minerd.exe and svchostl.exe keep coming back! Please help"  but I did not see a Fix.

 

Any Help!

Hi there,
my name is Marius and I will assist you with your malware related problems.

Before we move on, please read the following points carefully.

  • First, read my instructions completely. If there is anything that you do not understand kindly ask before proceeding.
  • Perform everything in the correct order. Sometimes one step requires the previous one.
  • If you have any problems while following my instructions, Stop there and tell me the exact nature of your problem.
  • Do not run any other scans without instruction or add/remove software unless I tell you to do so. This would change the output of our tools and could be confusing for me.
  • Post all logfiles as a reply rather than as an attachment unless I specifically ask you. If you can not post all logfiles in one reply, feel free to use more posts.
  • If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.
  • Stay with me. I will give you some advice about prevention after the cleanup process. Absence of symptoms does not always mean the computer is clean.
  • My first language is not english. So please do not use slang or idioms. It could be hard for me to read. Thanks for your understanding.

 
 
 
Ensure you have backed up the data stored on this server before you proceed.
 
 
Scan with FRST in normal mode

Please download Farbar's Recovery Scan Tool to your desktop: FRST 32bit or FRST 64bit (If not sure: Start --> Computer (right click) --> properties)

  • Run FRST.
  • Don´t change one of the checkboxes and hit Scan.
  • Logfiles are created on your desktop.
  • Poste the FRST.txt and (after the first scan only!) the Addition.txt.

 

 

 

Scan with TDSS-Killer

Please read and follow these instructions carefully. We do not want it to fix anything yet (if found), we need to see a report first.

Download TDSSKiller.exe and save it to your desktop

  • Execute TDSSKiller.exe by doubleclicking on it.
  • Press Start Scan
  • If Malicious objects are found, do NOT select Cure. Change the action to Skip, and save the log.
  • Once complete, a log will be produced at the root drive which is typically C:\ ,for example, C:\TDSSKiller.<version_date_time>log.txt



Please post the contents of that log in your next reply.
