Possible CMD.exe infection. Need help please


Recommended Posts

Hello. recently I have noticed a lot of BSOD crashes with various error messages.  I worked on it for several days and found that a possible cause was from a bad driver which MS updates told me I needed.  The BSODs resolved when I removed the driver, but it clued me in to another potential problem.  I have noticed that a cmd.exe is running on the computer.  When I searched online, there was a mixed reaction to this app.  It is present in my C:\Windows\System32 folder and everything I have read says that is bad news.  Any help would be greatly appreciated.

Hello and :welcome:

 

Please download Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system. If you are not sure which version applies to your system download both of them and try to run them.
Only one of them will run on your system, that will be the right version.

  • Double-click to run it. When the tool opens click Yes to disclaimer.
  • Press Scan button. 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 makes also another log (Addition.txt). Please attach it to your reply.

Yes, there was an infection a month ago. We will clean the remnants now:

 

FRST.gif Fix with Farbar Recovery Scan Tool

icon_exclaim.gif This fix was created for this user for use on that particular machine. icon_exclaim.gif


icon_exclaim.gif Running it on another one may cause damage and render the system unstable. icon_exclaim.gif

Download attached fixlist.txt file and save it to the Desktop:

Both files, FRST and fixlist.txt have to be in the same location or the fix will not work!

  • Right-click on FRST.gif icon and select RunAsAdmin.jpg Run as Administrator to start the tool.
    (XP users click run after receipt of Windows Security Warning - Open File).
  • Press the Fix button just once and wait.
  • If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
  • When finishes FRST will generate a log on the Desktop, called Fixlog.txt.

Please attach it to your reply.

Since there are no more problems, we can declare this PC clean thumbs_up_smiley.gif

Now, we can proceed with post-cleanup procedures. Let's remove my tools and create a new, non infected restore point concurrently deleting old ones.


Step 1. - Creation of system restore point and tools removal.


Download DelFix by Xplode and save it to your desktop.

  • Run the tool by right click on the 51a5ce45263de-delfix.png icon and Run as administrator option.
  • Make sure that these ones are checked:
    • Remove disinfection tools
    • Purge system restore
    • Reset system settings

  • Push Run and wait until the tool completes his work.
  • All tools we used should be gone. Tool will create an report for you (C:\DelFix.txt). I don't need it for review.


Tool deletes old system restore points and creates a fresh system restore point after cleaning.


Step 2. - Tips and tricks to keep your computer clean, safe and in a good shape.

Maintenance tips:


Additional software that I personally use and install on all my clients devices:

  • Malwarebytes' Anti-Malware(paid version highly recommended) - to scan your system from time to time in search for malware.
  • Malwarebytes' Anti-Exploit - to prevent plenty of mostly exploited vulnerabilities.
  • McShield - to prevent infections spread by removable media.
  • Unchecky - to prevent from installing additional foistware, implemented in legitimate installations.
  • uBlock - to surf the web without annoying ads!
  • Qualys BrowserCheck - cloud service that scans your browsers and plugins to see if they’re all up-to-date.

My help is free for everybody.
