How to create a Malwarebytes USB Boot able flash drive which contains malware antivirus software?

Simple, you download the ISO from Malwarebytes ISO, then use 7 zip to extract the ISO onto a USB flash drive then use the Malware USB to remove computer malware and computer viruses. The Image is updated to contain new definitions for the malware antivirus. If you have a network connection which gets detected you will be able to update virus definition files to update the  internet anti virus on this custom USB stick.


Open a CLI or CMD window as a the administrator then type in diskpart.

To find out which USB you want to make into a Custom USB stick use the command list disk. If you check in the image below, you can see that disk 4 is 7643 MB, that is an 8GB USB stick which I want to make into a Custom USB. Therefore I need to use Select Disk 1 to make the Custom USB.

Custom USB, CUSTOM USB Stick

In diskpart type the following commands:

select disk #

detail disk – this command is for you to see if you selected the right disk, check out the size to figure out which disk you have selected, if you still can’t figure it out, read on and follow the images.

select partition #



The # sign stands for the disk number you’re working with or the partition number you are working with.

cmd administrator, cli administrator, run cli administrator, run cmd administrator



diskpart, partition disk, make partitions, make disk partitions, disk partition, disk partitions


selct disk, select disk number, select disk #



detail disk, diskpart detail disk, disk details, volume details


select partition, active partition, partition active, select partition number, select partition #, select partition active



computer disk management, disk management, disk snapin, disk management snapin, computer management snapin

If you don’t know your disk number check out the computer management disk management and there you can see the disk number assigned to each disk.

After Diskpart has loaded you have to make the partition active on the USB flash drive.

Then You have to use the function key F12 to load the boot options or the assigned function key for your computer. Then select the USB key drive to boot off and you should be able to use the Malwarebytes Bootable USB just as the MalwareBytes boot CD to remove computer malware and computer viruses.

Boot the USB key and activate the free antivirus software by running mbam at the command prompt. This  Custom USB stick has proven to be an excellent malware antivirus software  even in business virus protection.

Created bootable USB trying both FAT and FAT32 file system following the instructions above. Verified that partition is active in Disk Management. Attempts at booting from this USB fail on Dell OptiPlex 755 with either ‘USB Device’ or ‘Onboard or USB Floppy’ enabled in BIOS.

Same ISO works when burned to a DVD and is bootable on same machine.

Hello Rick,

Now try to copy the dvd contents onto that Bootable USB. Not the ISO. The computer make is irrelevant in this question. It should work, or if not, then something else is not as it should.

Hello Mrs V. If you have done everything correctly then when you have successfully booted from the Malware CD, then you should see the screen at this post:

In the picture you see which commands to run to start the necessary software for scanning your computer. In addition to successfully run through this process you need to read these other posts:

Not sure if I’m doing this wrong, the Malware USB works, but the Malwarebytes Version is 1.7 not 2.0.2. I still can update the REF file, but again the Malwarebytes Version is 1.7.

Yea the new version of Malwarebytes has a new interface. I haven’t had the time to integrate it with the ISO.

Hello, I download the ISO and loaded it on a USB stick like you said with 7-zip, it boots just fine, I went to update Malwarebytes to the newest version you state and it downloaded it, but when it went to install it crashed the WinPE so I booted and it fails to boot from the USB stick, so I re-did the ISO back to USB stick boots just fine, download malwarebytes update and crashes, won’t boot again from USB stick, I did this over and over 5 times and I gave up, can you make a new version of your ISO with the newest Malwarebytes from today or tomorrow date as of Oct 20th 2014… I tried to update but no way jose…. this is a great ISO but it needs updated manually. please update the other programs as well I need to fix my Wife’s computer and don’t want to boot it until I can run the newest scan of Malwarebytes… Thanks for your great work.

You can just update the definitions. I am not sure you can just install malwarebytes into that ISO, is not as you would install it on a computer. There are a few things you need to do manually to get it to work. But if you just update the definitions then you will be able to detect the newest software.

Has anyone every created a bootable USB that has multiple antivirus engines loaded. The idea is that computer boots from the usb drive, then you get a menu of which antivirus iso to boot from. So I want to scan a system using 5 different scan engines. I would boot, choose Kaspersky, scan, clean and reboot, boot from usb stick again, then choose a different antivirus like Bitdefender. All of this on only one USB drive. Instead of needing a different usb drive per AV scanner.

The TCM CD/USB has three free scanning tools: Malwarebytes, Superantispyware and Sophos free removal tool. But you only boot one OS, and then you can separately run beach one, without having to boot in between them. What you are interested I think is the Multiple boot CD/DVD/USB which can be found here: and here:

Sorry about that. I probably was trying to address a more novice category of computer users.
