    Good morning all

    I have a recurring nightmare where my disk space is being gobbled up by files that have to do with something called Sandblast.

    I've noticed in my googling that it has something to do with some endpoint protection product, specifically zonealarm, which has been uninstalled, yet these files are UNdeletable by me as administrator or me as me.

    Can anyone assist me in how to rid my drive of these folders and make them not re-occur?

    Many thanks

    Hi @UnklPlatz and welcome to W10F. I never heard of that one. Best way to avoid situations like that is to make and maintain an offline backup of system disk and any valuable files. Nothing else can actually 100% save you from malware.

    Thank you @CountMike for the welcome.
    This is the kind of nonsense that happens, I'm sure, when you speed through an installation process of a downloaded app (specially a "free" one), without taking note of what other bits it says it's going to install. Just a guess.
    But strange and frustrating (infuriating) none the less.
    The folder it makes is not as large as it used to be though. It's now under 500MB but still that's half a gig that i'd have liked to decide myself on what to do with

    Sandblast is indeed related to Zonealarm (see for more info:
    Check Point SandBlast

    To really remove the Sandblast element and Zonealarm using the removal tool provided by Zonealarm, see if this post by "Blank__Stares" on this reddit thread helps:

    "PLEASE FOLLOW THE STEPS BELOW: 1. Press the Windows Key on you keyboard or click on the windows icon/start button on the lower left corner of your desktop. 2. Click Control Panel and go to PROGRAMS & FEATURES. 3. Look for ZoneAlarm and uninstall it. Reboot PC when prompted. 4. When your machine is back on, run the CLEAN.exe file which is the updated Clean tool of ZA to remove residual file of the old version. Please use this link: 5. Reboot when prompted 6.After your PC reboots clear your Windows temporary file cache by following the steps below: - Press WINDOWS KEY ->Type in search "RUN" -> Press Enter NOTE: If you do not have the Run option on the Start menu, you can press and hold the Windows logo key and tap the letter R . - Type %temp% and click OK - Select all of these files and delete them - Empty your recycle bin".

    What is SandBlastBackup folder and why is it +50gb folder, hidden and cannot be deleted without admin rights? : techsupport

    nb: Make a system image using your favoured imaging program before you proceed with the removal (just in case things go wrong)

    Good luck.
