UPDATE! The BLTDVS Toolkit in its original form as referred to in the linked article below is now obsolete. The current state of the art has yielded self-contained USB installer tools for most of the popular anti virus rescue CDs.
I have updated this article with the latest information and put two versions of popular rescue CD USB installers in the revised BLTDVS Toolkit which is still available for download from the original location when you sign up for my newsletter list (send a blank email to: firstname.lastname@example.org to receive download instructions).
With all the various flavors of anti virus rescue CDs around, it’s an easy matter to create a CD bootable anti virus scanner that will operate offline to disinfect even the worst malware infestation. In most cases, all you have to do is download the vendor’s latest rescue CD ISO image, burn it, boot it, and let the program do its thing. Easy. Making a bootable USB thumb drive from the ISO is another matter.
Extracting the files from an ISO image to the thumb drive requires a few tricks to accomplish. You can, of course, just download my BLTDVS toolkit from How to make a bootable thumb drive virus scanner for NTFS: 2009 update,? and follow the included instructions but, that toolkit is specifically optimized to work with the Kaspersky Rescue CD; what if you prefer to use a different vendor’s rescue package?
There’s a cool open source utility called UNetbootin that allows you to create bootable live USB drives for a variety of Linux distributions without requiring you to burn a CD. This is perfect since most, if not all, of the rescue CDs are Linux based. The UNetbootin site has full instructions on how to use the tool complete with screen shots. There are also several utilities and rescue tools listed for use with UNetbootin.
- Download the BitDefenderRescueCD_###.iso into the BLTDVS_toolkit folder if you have it, or make a folder of your own.
- Download and launch the Universal USB Installer or launch it from the BLTDVS_toolkit folder. Select the option “Try unlisted Linux ISO (Old Syslinux)” then browse to the BitDefender ISO file.
