I did the unthinkable and attempted to install some questionable software. Now it seems my computer is infected. Any open Windows Explorer window will close after a few seconds and multiple instances of Internet Explorer are magically open in the task manager using CPU and DISK.

 

I am running Windows 8.1 Pro x64

I have tried a normal scan using malwarebytes and adwcleaner but the only thing that popped from malwarebytes was PUP.Optional.Somoto.  I am currently running the ESET online scanner and am willing to run a bunch of tools and post lots of logs :)

 

Thanks in advance for the help.

ESET online scanner results:
 

C:\Users\All Users\Microsoft\Crypto\RSA64\rsa64.dll a variant of Win64/Sathurbot.A trojan
C:\Users\All Users\Microsoft\Crypto\RSA64\temp\tmp809A.exe a variant of Win32/Injector.BIDT trojan
C:\ProgramData\Microsoft\Crypto\RSA64\rsa64.dll a variant of Win64/Sathurbot.A trojan cleaned by deleting - quarantined

C:\Users\blave\AppData\Local\Temp\rd.exe a variant of Win32/OutBrowse.AB potentially unwanted application deleted - quarantined
C:\Users\blave\AppData\Local\Unlmedia\chrome.dll a variant of Win32/Packed.Themida.AAJ trojan cleaned by deleting (after the next restart) - quarantined

Operating memory multiple threats

It was able to remove all except the first two. I used Unlocker to delete the entire contents of C:\Users\All Users\Microsoft\Crypto\RSA64 which seemed to solve my issues with explorer.exe and iexplore.exe going crazy. Still not sure if there are any residual files hanging around.
 
In Firefox and Chrome I'm still experiencing small Flash pop-up window overlays on some webpages and browser redirects to different pages than what I'm trying to browse to.

Hello tberger

about the first two..
Short description

The trojan serves as a backdoor. It can be controlled remotely.

Installation

The trojan is often included in the installation packages of programs downloaded from untrustworthy sources.
http://www.virusradar.com/en/Win32_Sathurbot.A/description


One or more of the identified infections is a backdoor trojan.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

When Should I Format, How Should I Reinstall

We can still clean this machine but I can't guarantee that it will be 100% secure afterwards. Let me know what you decide to do.
How do I get help? Who is helping me?For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear....Become a BleepingComputer fan: Facebook

I'm going to format. It's about that time to do a fresh install anyways :)

It's the choice I'd have made.. Have a great day!!

If you have questions on doing that ask in Win 8
