Attach the log file.
- When you click the Reply button, there is an Additional Options link, this expands the options to attach a file, that can be an image file or a text file (.log or .txt).

The actual file name rings bells for me it looks randomly generated and a google search only finds only two hits on the name and they relate to this topic, which in itself is suspicious for a dll file.

There is no such file in that location on my XP Pro system.

Windows 10 Home 64bit/ Acer Aspire F15/ Intel Core i5 7200U 2.5GHz, 8GB DDR4 memory, 256GB SSD, 1TB HDD/ avast! free 24.3.6108 (build 24.3.8975.762) UI 1.0.801/ Firefox, uBlock Origin, uMatrix/ MailWasher Pro/ Avast! Mobile Security

Working on the 4th MBAM scan while in safe mode.It finds a few infected files each run ,however none seem to match what Avast finds at EACH reboot.The name of said .dll file changes with each restart.



The OTS file is as follows

C:\Windows\System32\spool\prtprocs\w32x86\93179s1e9.dll This infection indicates a TDSS rootkit

Start OTS. Copy/Paste the information in the quotebox below into the panel where it says "Paste fix here" and then click the Run Fix button.

Quote
[Unregister Dlls]
[Files/Folders - Modified Within 30 Days]
NY ->  cfdf2354.job -> C:\Windows\tasks\cfdf2354.job
[Files - No Company Name]
NY ->  cfdf2354.job -> C:\Windows\tasks\cfdf2354.job
[Alternate Data Streams]
NY -> @Alternate Data Stream - 85 bytes -> C:\ProgramData:$SS_DESCRIPTOR_1VVTV9VTMVFBF1VJWVBH4P6XLVVVVVVVVVVVVVV
[Empty Temp Folders]
[EmptyFlash]
[CreateRestorePoint]
[Reboot]

The fix should only take a very short time. When the fix is completed a message box will popup telling you that it is finished. Click the Ok button and Notepad will open with a log of actions taken during the fix.  Post that information back here

THEN

Please read carefully and follow these steps.
  • Download TDSSKiller and save it to your Desktop.
  • Extract its contents to your desktop.
  • Once extracted, open the TDSSKiller folder and doubleclick on TDSSKiller.exe to run the application, then on Start Scan.





  • If an infected file is detected, the default action will be Cure, click on Continue.





  • If a suspicious file is detected, the default action will be Skip, click on Continue.





  • It may ask you to reboot the computer to complete the process. Click on Reboot Now.





  • If no reboot is require, click on Report. A log file should appear. Please copy and paste the contents of that file here.
  • If a reboot is required, the report can also be found in your root directory, (usually C:\ folder) in the form of "TDSSKiller.[Version]_[Date]_[Time]_log.txt". Please copy and paste the contents of that file here.
I will review the information when it comes back in.  I see you have also run Combofix could you post that log as well

The block on this thread has stopped!!!!MBAM no longer stopping attacks every 3 seconds, Keeping fingers crossed!!!!
Will run Boot scan,MBAM,Panda,and Sophos Anti rootkit For good measure.

Both OTS and Combofix logs look good  ;D

Lets clear the tools 

I will remove my tools now and give some recommendations, but I would like you to run for 24 hours or so and come back if you have any problems

 Now the best part of the day ----- Your log now appears clean  :thumbsup:

A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset  System Restore points:

Run OTS
  • Under the "Paste fix here" box, paste in the following

    Quote
    :Commands
    [resethosts]
    [purity]
    [emptytemp]
    [EMPTYFLASH]
    [CLEARALLRESTOREPOINTS]
    [Reboot]
  • Then click the Run Fix button at the top
  • Let the program run unhindered, reboot the PC when it is done

Click Start > Run  and copy/paste the following bolded text into the Run box and click OK:

ComboFix /Uninstall

Run OTS and hit the cleanup button.  It will remove all the programmes we have used plus itself.  MBAM can be uninstalled via control panel add/remove along with ERUNT.  But they may be useful tools to keep

We will now confirm that your hidden files are set to that, as some of the tools I use will change that
  • Click Start.
  • Open My Computer.
  • Select the Tools menu and click Folder Options.
  • Select the View Tab.
  • Under the Hidden files and folders heading select Do not show hidden files and folders.
  • Click Yes to confirm.
  • Click OK.

SPRING CLEAN
 
Download and run Puran Disc Defragmenter

Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes: It is critical to have both a firewall and anti virus to protect your system and to keep them updated.

To keep your operating system up to date visit To learn more about how to protect yourself while on the internet read our little guide  How did I get infected in the first place ?
Keep safe  :wave:
