    A collection of bootable antivirus boot disks on a single USB device.

    UEFI mode is unsupported, and the UEFI menu has been disabled.
    Most of these discs will not boot under UEFI. So boot this USB to the RED BIOS menu.
    If the boot menu is GREEN, then you'll be notified that you need to boot into Legacy BIOS boot mode.



    Hardware requirements:

    64-bit CPU
    2GB of RAM
    An empty 8GB USB drive
    This USB disk will not receive regular rapid updates. It will only be updated to address and fix issues as needed.
    Fell free to keep it updated on your own, and post any and all questions here. I, and other members here will be happy to help where we can.

    I'm seeding still, and will be seeding for about a week until it gets faster and stable. It's only uploading at about 2 Megabytes per second right now.

    Will definitions for these antiviruses will be updated frequently inside new version of this package?
    Would be best if would be some sort of script or tool to update definitions on computer with network before plug in to test machine (which if is suspected to be infected should stay offline).

    No, but Malwarebytes's definitions are persistent, since they reside in a folder on the USB, not inside an ISO. So every time you Update Malwarebytes, it keeps it's new definitions between reboots. (It's the only ISO I made personally)

    I can't vouch for the others, but most of them will offer to update their definitions once you're connected online. I will not be updating this any further, as this will be the only release.

    Hi to all
    I have two questions:
    One, it seems when I install the image contained in the 7zip files into an USB drive,I can only see the partition where the Medicat is ( i.e.: I put it in a 32Gb pendrive, and if I connect it with windows started, in "properties" mode, it displays "only" 8Gb
    And I don't know if I have done something bad, but the pendrive doesn't start when I want to boot with it through BIOS... :(

    Two: Can I update the ISOs of the antivirus only with replacing the old with a new version?

    Thanks in advance... and sorry about my english (I know it's the worst of everything)

    1.) The big partition is normal, the VTOYEFI partition doesn't have a drive letter by default. Did you follow all the steps in the instructions? Because it should be bootable. Check your BIOS settings and make sure Legacy BIOS/CSM is enabled. Also turn off Secure Boot too. Use Ventoy2Disk's INSTALL button and try again.

    2.) Yes, you can update the ISOs by replacing them with new versions. But if you don't edit ventoy.json to match, their icons won't show up. Not a huge deal, but worth mentioning.

    Yeah, format it as FAT32 WITH 4K or 2K cluster size, and then extract the files to the drive. Should fit your 8GB just fine that way.

    Small update:

    Code:
    =========================
    Changelog for v20.12:
    =========================
    
    Updated:
    ~ I actually downgraded the 2018 Malwarebytes Bootable WinPE to a 2016 version for added stability, it boots up WAY faster, uses much less RAM, and has a smaller file size. Has a startup sound with audio instructions to get you started. This older version is only temporary, until I have the time to build a proper one that's more up to date.
    ~ Minimum memory requirements have been reduced at the bottom of this changelog, to better reflect the memory needs of the included WinPE WIM files. Minimum RAM requirements below has dropped from 3GB down to 2GB, but you'll still want 4GB or more for comfortable usage. Luckily most modern PCs and laptops come with no less than 4GB these days.
    ~ Malwarebytes virus definitions to v2020.12.08.03
    
    Menu Changes:
    # The UEFI menu has been completely disabled to maximize boot compatibility. If you reach the green warning screen, you need to boot the USB drive in Legacy BIOS (CSM) mode.
    
    Fixed:
    * Further improvements to overall system stability and other minor adjustments have been made to enhance the user experience.

    I also changed it from burning an image file to the simpler un-zip method:
    Just make your Ventoy USB stick, format it as FAT32, and extract the files to the drive. It's that easy.

    UEFI mode has been disabled, as most of these discs require BIOS booting. So if you attempt to boot into UEFI mode, you'll be greeted with this screen:

    Hi again,Jayro..
    I try to extract the files to an USB pendrive with FAT32 filesystem,as you said in the other post...
    But FAT32 doesn't support files larger than 4Gb...must I format the pendrive in NTFS , like in MedicatUSB?

    None of the files I have included here are over 4GB, so I don't see why you would need NTFS.

    I just started seeding it again, and fixed the MEGA link. Sorry for overlooking the MEGA link not being finished, I forgot to paste the link.

    I'm seeding right now, so it might just be slow.
