High Memory from CMD.exe and Malwarebytes showing outbound requests malware


Recommended Posts

I've been getting alerts that System32\cmd.exe was sending outbound requests that were being blocked as malware. As well as seeing cmd.exe was showing in my task manager with a high amount of memory usage, which leads me to believe there's some malware but I didn't seem to find it on a scan. But it seems others have possibly had a similar issue resolved.

Welcome smile.png
 
I'll be helping you with your computer.
 
Please read this post completely before beginning. If there's anything that you do not understand, please don't hesitate to ask before proceeding.
 
Please take note of the guidelines for this fix:

  • Please note that I am a volunteer. I do have a family, a career, and other endeavors that may prevent immediate responses that meet your schedule. Do note that the differences in time zones could present a problem as well. Your patience and understanding will be greatly appreciated.
  • First of all, the procedures we are about to perform are specific to your problem and should only be used on this specific computer.
  • Do not make any changes to your computer that include installing/uninstalling programs, deleting files, modifying the registry, nor running scanners or tools of any kind unless specifically requested by me.
  • Please read ALL instructions carefully and perform the steps fully and in the order they are written.
  • If things appear to be better, let me know. Just because the symptoms no longer exist as before, does not mean that you are clean.
  • Continue to read and follow my instructions until I tell you that your machine is clean.
  • If you have any questions at all, please do not hesitate to ask before performing the task that I ask of you, and please wait for my reply before you proceed.
  • Scanning with programs and reading the logs do take a fair amount of time. Again, your patience will be necessary. smile.png

  • Start FRST (FRST64) with Administrator privileges 
  • This time around Press the Fix button and wait
  • When finished, a log file (Fixlog.txt) will pop up and saved in the same location the tool was ran from.

Please attach this file in your next reply.

  • Enable Eset to detect and quarantine potentially unwanted applications
  • Click StartScan
  • The program will begin to download it's virus database. The speed may vary depending on your Internet connection.
  • When completed, the program will begin to scan. This may take several hours. Please, be patient.
  • Do not do anything on your machine as it may interrupt the scan.
  • When completed it'll show a list of "Threats found", click beneath it on Save to text file.... and save it as ESET log.txt on your Desktop.
  • Then click Do not clean. Place a checkmark at Delete application's data on close, click Finish and close the program.

Yes. The offending files were deleted.

Stay away from torrents, P2P networks and Registry cleaners.
 
Many peer-to-peer networks are under constant attack by people with a  variety of motives.
 
Examples include:

  • poisoning attacks (e.g. providing files whose contents are different than the description)
  • denial of service attacks (attacks that may make the network run very slowly or break completely)
  • defection attacks (users or software that make use of the network without contributing resources to it)
  • insertion of viruses to carried data (e.g. downloaded or carried files may be infected with viruses or other malware)
  • malware in the peer-to-peer network software itself (e.g. distributed software may contain spyware)
  • filtering (network operators may attempt to prevent peer-to-peer network data from being carried)
  • identity attacks (e.g. tracking down the users of the network and harassing or legally attacking them)
  • spamming (e.g. sending unsolicited information across the network- not necessarily as a denial-of-service attack)

Congratulations.
 
Use this application to remove tools used and their quarantined items:
 
Please download KpRm by Kernel-panik and save to your Desktop.

  • Click on KpRm.exe to run the tool.

Vista/Windows 7/8/10 users right-click and select Run As Administrator.

  • Put a check mark next to these items:

- Delete tools

- Create Restore Point

- Delete now

  • Click the "Run" button.

  • When the tool has finished, it will create and open a log report and delete itself.
