Probable infection from .doc file, can't locate with scan

Recommended Posts

I received an email from a trusted source with a .doc file attached. It quickly tricked me into opening it on my desktop, enabling editing and then content. I quickly realized I had probably infected myself, and ran Malwarebytes threat scan, Windows Defender deep and offline scan, and neither were able to locate any invader. During the first Windows Defender scan, my desktop behaved strangely, with background programs flickering and the Start bar disappearing. This behavior was not observed on restart, as part of Windows Defender's offline scan.

Now, I am following the steps listed looking for assistance.

I have attached the log files from Malwarebytes, and the Farbar Recovery Scan Tool, and the document which I suspect is contaminated.

Please help.

Hello @BenABT

Yes the file was infected. 7 engines detected it.
https://www.virustotal.com/gui/file/4f1cfea3735843a3d1bc3c0f81079d08bb9cde43347303820f84a5ef9a13a5b2/detection

What is this batch file for? Did you create it or enable it in scheduled tasks? I'm assuming it probably came from some type of Driver Setup Utility program which is almost certainly snake oil.
C:\Program Files\DriverSetupUtility\FUB\FUB_Send.bat

 

I see you have µTorrent installed. That is an open invitation to increased threats to your system. I would highly discourage it's use and recommend you uninstall it.

File sharing involves using technology that allows internet users to share files that are housed on their individual computers. Peer-to-peer (P2P) applications, such as those used to share music files, are some of the most common forms of file-sharing technology. However, P2P applications introduce security risks that may put your information or your computer in jeopardy.  Risks of File-Sharing Technology

You also have Java installed. Nothing wrong with that if you really need it. In the vast majority of cases most users do not need Java. If you don't need it I'd recommend you uninstall it too as it is a very often targeted software program.

 

Please download the attached fixlist.txt file and save it to the Desktop.
NOTE. It's important that both files, FRST or FRST64 and fixlist.txt are in the same location or the fix will not work.

NOTICE: This script was written specifically for this user, for use on this particular machine. Running this on another machine may cause damage to your operating system.

Run FRST or FRST64 and press the Fix button just once and wait.
If the tool needs a restart please make sure you let the system restart normally and let the tool complete its run after restart.
The tool will make a log on the Desktop (Fixlog.txt). Please attach or post it to your next reply.

Note: If the tool warned you about an outdated version please download and run the updated version.

fixlist.txt

Thanks

The log looks pretty good but let's go ahead just in case and run a new set of scans to double-check we haven't missed anything.

 

Please run the following steps and post back the logs as an attachment when ready.

STEP 01

  • If you're already running Malwarebytes 3 then open Malwarebytes and check for updates. Then click on the Scan tab and select Threat Scan and click on Start Scan button.
  • If you don't have Malwarebytes 3 installed yet please download it from here and install it.
  • Once installed then open Malwarebytes and check for updates. Then click on the Scan tab and select Threat Scan and click on Start Scan button.
  • Once the scan is completed click on the Export Summary button and save the file as a Text file to your desktop or other location you can find, and attach that log on your next reply.
  • If Malwarebytes won't run then please skip to the next step and let me know on your next reply.

STEP 02

Please download AdwCleaner by Malwarebytes and save the file to your Desktop.

  • Right-click on the program and select RunAsAdmin.jpg Run as Administrator to start the tool.
  • Accept the Terms of use.
  • Wait until the database is updated.
  • Click Scan Now.
  • When finished, please click Clean & Repair.
  • Your PC should reboot now if any items were found.
  • After reboot, a log file will be opened. Copy its content into your next reply.

 

RESTART THE COMPUTER Before running Step 3

STEP 03
Please download the Farbar Recovery Scan Tool 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

  • Double-click to run it. When the tool opens, click Yes to disclaimer.
  • Press the Scan button.
  • It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
  • The first time the tool is run, it also makes another log (Addition.txt). If you've, run the tool before you need to place a checkmark here.
  • Please attach the Additions.txt log to your reply as well.

 

Thanks

Ron

Okay, for now please ignore. I will report it to the Development Team and let them know.

How is the computer running now otherwise?

Running fine, but that doesn't mean much, as I didn't notice any behavior problems before, either.

Thank you very, very much for your help with this. I didn't know what I would do, when the antivirii came up clean despite the clear danger.

Here is some information to help you keep your computer clean and safer going forward. I realize it's a lot to read and take in but just read more each day as you have time. In the long run even years from now you'll be better informed and able to manage your computer better on your own.

 

If you're not backing up your data and you're still using Google Chrome then you're just not serious about Privacy, Safety, and protecting your data. Malwarebytes is a fantastic program but you still need to back up your data and you still need to block scripts and Ads in your browser. 
If you're still using Google Chrome I would highly suggest you consider using Firefox instead. For more advanced users you might consider installing NoScript as well (it does have a higher learning curve though)

Help Secure your browsers
