Understanding just how compromised my PC is

Recommended Posts

I have just discovered that my PC has been compromised when i found that my AV had been disabled completely (BullGuard), after which i found that Defender had been removed and updates are stuck in a loop checking for the latest versions. I used Malwarebytes to scan and remove everything that is infected and then repaired windows by refreshing from an ISO, i am not sure if that has fixed everything and i would like to know what the virus(es) were doing to see if any of my personal data i.e. passwords and bank info are at risk, any help you can give me in understanding the logs from the virus scan will be greatly appreciated.

The Logs are as follows:

Hello. Liam    :welcome:

My name is Maurice. I will be helping and guiding you, going forward on this case.
Please put away the Windows ISO & lets not use it anymore.  That Windows version ( the build from Spring 2019 ....build 1903 ) is out of support.  I will guide you later to getting the Windows OS to be updated to a more current release version.


Please follow my directions as we go along.  Please do not do any changes on your own without first checking with me. 
Please only just attach   all report files, etc  that I ask for as we go along.  I

If you will be away for more than 4 consecutive days,  do try to let me know ahead of time, as much as possible.

I would appreciate  getting  additional / fuller  important details from this machine in order to help you forward.
 NOTE: The tools and the information obtained is safe and not harmful to your privacy or your computer, please allow the programs to run if blocked by your system.

Do have patience while the report tool runs.  It may take several minutes.  Just let it run & take its time.  You may want to close your other open windows so that there is a clear field of view.
Download Malwarebytes Support Tool
    Once the file is downloaded, open your Downloads folder/location of the downloaded file
    Double-click mb-support-1.80.848.exe  to run the report

Once it starts, you will see a first screen with 2 buttons.  Click the one on the left marked "I don't have an open support ticket".

        You may be prompted by User Account Control (UAC) to allow changes to be made to your computer. Click Yes to consent.
    Place a checkmark next to Accept License Agreement and click Next
Now click the left-hand side pane "I do not have an open support ticket"

    You will be presented with a page stating, "Get Started!"
    Do NOT use the button “Start repair” !   But look instead at the far-left options list in black.

    Click the Advanced tab on the left column
    Click the Gather Logs button
    A progress bar will appear and the program will proceed with getting logs from your computer.  Please do have patience.  It takes several minutes to gather.
    Upon completion, click a file named mbst-grab-results.zip will be saved to your Desktop. Click OK.  Then Exit the tool.

    Please attach the ZIP file in your next reply.

Please know I help here as a volunteer.  and that I am not on 24 x 7.
Help on this forum is one to one.

Added other NOTE:  For a general description of "Backdoor.Agent"  at the Malwarebytes Threat Center see this page https://blog.malwarebytes.com/detections/backdoor-agent/

As to "trojan.agent"  See  https://blog.malwarebytes.com/detections/trojan-agent/

I can't possibly know what may have been compromised off your computer.

The following is typical advice for someone who might be a victim of identity theft.
You are strongly advised to do the following 
1.  Watch closely all bank, financial accounts & credit card statements
2. For later, after we reach the point where I advise that the system is OK.  Then, on a clean computer, change ALL your online passwords -- for email, for banks, financial accounts, PayPal, eBay, online companies, any online forums or groups.
be sure you use strong passwords.     

Do NOT change passwords or do any transactions while using this current  computer until I give the all clear.  Do not play online games.  Do not do any online shopping.
