Computer Hope

I have something on my computer that is filling the root drive up with 1.9GB files.  I can't delete it or the files.  I can't install any utilities to run either.
It's called SandBlastBackup and my drive is completely full of 1.9GB files from it.

Any advice or suggestions are appreciated guys.

I'm running an 15 3570 with 16GB of RAM and a 500GB Samsung SSD.  The GPU is a GT 1030 and I'm running Windows 10 build 1803 Pro 64bit.

Leading up to this I had installed Zone Alarm Firewall and another firewall to test, it's Glasswire.

I'm running ESET online scanner right now, it's found a few threats so far, so hopefully that will help

Hello and welcome to Computer Hope Forum. My name is Dave. I will be helping you out with your particular problem on your computer.

1. I will be working on your Malware issues. This may or may not solve other issues you have with your machine.
2. The fixes are specific to your problem and should only be used for this issue on this machine.
3. If you don't know or understand something, please don't hesitate to ask.
4. Please DO NOT run any other tools or scans while I am helping you.
5. It is important that you reply to this thread. Do not start a new topic.
6. Your security programs may give warnings for some of the tools I will ask you to use. Be assured, any links I give are safe.
7. Absence of symptoms does not mean that everything is clear.

If you can't access the internet with your infected computer you will have to download and transfer any programs to the computer you're using now and transfer them to the infected computer with a CD-RW or a USB storage device. I prefer a CD because a storage device can get infected. If you use a storage device hold the shift key down while inserting the USB storage device for about 10 secs. You will also have to transfer the logs you receive back to the good computer using the same method until we can get the computer back on-line.

Hi SuperDave, it's been a long time, I hope that you're doing well.

I've done what you laid out for me, the logs are below.


<edit>  I'm going to try downloading those Linux ISO's again and see if it happens again, or should I hold off on that?  </edit>

I really want to thank you for your time and effort SuperDave, I think it's solved.  I haven't had a problem since.

Please hold off on that until we see what's happening with this computer.

You have two AV's active on your computer: Avast and Windows Defender. WD is the resident AV that comes with Windows 10. You should uninstall Avast.

ESET Online Scanner
Note : If you use Internet Explorer to get the ESET Online Scanner, you won't have to download, nor install the tool, as everything will be ran in a contextual (pop-up) window of Internet Explorer. However, for every other browsers, you will have to download and install ESET Online Scanner. In this set of instruction, I'll use Google Chrome to download it and run it (since a lot of people will do it), however, except for the download and installation procedure, the same instructions applies if you use Internet Explorer. Please note that two or three prompts will appear if you use Internet Explorer asking you to reload the page, authorize the application, execute it, etc. Accept all of them in order to run ESET Online Scanner.

    Download and execute ESET OnlineScan (on this window, click on ESET Smart Installer to trigger the download). People accessing this URL via Internet Explorer will start the integration process of ESET Online Scanner in their browser;
    Once the installation is done (it requires Admin Rights), check the following settings (two of them are under Advanced Settings, click on it to display them) :

        Enable detection of potentially unwanted applications;
        Scan archives;
        Scan for potentially unsafe applications;
        Optional : If you want to scan more drives, click on Change... and select the drives you want to include in the scan;

   

    After you're done checking these options, click on Start and ESET Online Scanner will download it's virus signature database before starting the scan;
   

    Once done, the scan will start automatically. Detections will appear at the bottom of the window. ESET Online Scanner can have an extremely long scan time that can last between 2 or 3 hours. So if you start the scan, do not interrupt it, let it complete until the end;
   

    After the scan is finished, a summary window will appear to give you the information about the scan. Then you'll have to the option to see what threads were found and to manage the threats that were quarantined;
   


    Click on List of found threats, it'll display every threat identified during that scan, their type and what action was taken against them. Click on Copy to clipboard to copy these results on our clipboard and post them in your next reply;
   


    Once you're done, click on the Back button;
    Check both checkboxes at the bottom: Uninstall application on close and Delete quarantined files before clicking on the Finish button;

It's been working fine and I managed to get the Linux ISO's without a hitch SuperDave

<edit>  I would like to pay you by giving you my first two children, where can I ship them for you?  </edit>

Ok. I will lock this thread. If you need more help please send me a pm.
