Good morning,
I just found out that there is this process beast.exe running on my PC (not always)
As far as I can understand this is not something good at all but it seems that MALAWAREBYTES which I have installed can not spot it. (See attached image)
What do you suggest me to do?
Thank you in advance for any piece of advice.
New fresh install is something I did two weeks ago and I would like to avoid it

Thank you!

Hello Santjago and welcome to Malwarebytes,

Run the following scan, lets see if anything shows up:

Download Farbar Recovery Scan Tool and save it to your desktop.

Alternative download option: http://www.techspot.com/downloads/6731-farbar-recovery-scan-tool.html

Note: You need to run the version compatible with your system (32 bit or 64 bit). 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.

If your security alerts to FRST either, accept the alert or turn your security off to allow FRST to run. It is not malicious or infected in any way...

Be aware FRST must be run from an account with Administrator status... If English is not your primary language Right click on FRST/FRST64 and rename FRSTEnglish/FRST64English

 
  • Double-click to run it. When the tool opens click Yes to disclaimer.(Windows 8/10 users will be prompted about Windows SmartScreen protection - click More information and Run.)
  • Make sure Addition.txt is checkmarked under "Optional scans"

  • Press Scan button to run the tool....
  • It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
  • The tool will also make a log named (Addition.txt) Please attach that log to your reply.


Thank you,

Kevin

Hiya Santjago,

I do not see Beast.exe in your logs, also registry search does not find it.. Continue:

Open Malwarebytes, select > small cog wheel top right hand corner, that will open "settings" from there select "Security" tab.

Scroll down to "Scan Options" ensure Scan for Rootkits and Scan within Archives are both on....

Close out the settings window, this will take you back to "DashBoard" select the Blue "Scan Now" tab......

When the scan completes quarantine any found entries...

To get the log from Malwarebytes do the following:
 
  • Click on the Detection History tab > from main interface.
  • Then click on "History" that will open to a historical list
  • Double click on the Scan log which shows the Date and time of the scan just performed.
  • Click Export > From export you have two options:
    Copy to Clipboard - if seleted right click to your reply and select "Paste" log will be pasted to your reply
    Text file (*.txt) - if selected you will have to name the file and save to a place of choice, recommend "Desktop" then attach to reply

     
  • Please use "Copy to Clipboard, then Right click to your reply > select "Paste" that will copy the log to your reply…


Next,

Download AdwCleaner by Malwarebytes onto your Desktop.

Or from this Mirror
 
  • Right-click on AdwCleaner.exe and select http://i.imgur.com/Spcusrh.pngRun as Administrator (for Windows Vista, 7, 8, 8.1 and 10 users)
  • Accept the EULA (I accept), then click on Scan
  • Let the scan complete. Once it's done, make sure that every item listed in the different tabs is checked and click on the Quarantine button. This will kill all the active processes
  • Once the cleaning process is complete, AdwCleaner will ask to restart your computer, do it
  • After the restart, a log will open when logging in. Please copy/paste the content of that log in your next reply


Next,

Download "Microsoft's Safety Scanner" and save direct to the desktop

Ensure to get the correct version for your system....

https://docs.microsoft.com/en-us/windows/security/threat-protection/intelligence/safety-scanner-download


Right click on the Tool, select Run as Administrator the tool will expand to the options Window
In the "Scan Type" window, select Quick Scan
Perform a scan and Click Finish when the scan is done.


Retrieve the MSRT log as follows, and post it in your next reply:

1) Select the Windows key and R key together to open the "Run" function
2) Type or Copy/Paste the following command to the "Run Line" and Press Enter:

notepad c:\windows\debug\msert.log

The log will include log details for each time MSRT has run, we only need the most recent log by date and time....

Let me see those logs in your reply...

Thank you,

Kevin..

Thank you
Malawarebytes scan found nothing, therefore no detection history to send
I will do what you next suggested in your list

I think if I run Autocad the process Beast.exe is back but it kind of freezes my pc, I am not sure I can run a scan after running Autocad

Please download the correct portable version (32-bit or 64-bit) of RogueKiller for your system and save the file to your computer Desktop.
