Kaspersky Rescue Disk Updater

Kaspersky Rescue Disk Updater is a Windows Command Script or a batch file which usesĀ KLUpdater to update the virus definitions of the Rescue Disk ISO.

Kaspersky Rescue Disk 10 can scan and remove viruses without booting into windows.The main disadvantage of Kaspersky Rescue Disk 10 is that it is not updated regularly.

Even when it is updated there is no option to update your existing iso with the changes.You will have to download the entire iso. So if you don’t download the rescue disk regularly, the virus definitions become out of date.

Even though the rescue disk has an option to update the virus definitions from the internet, it is not very useful as the updates are saved only on that particular computer.If you use it on another computer then you will have to download all the updates again.

Kaspersky Rescue Disk Updater fixes the above problems by updating your existing Kaspersky Rescue Disk ISO with the latest virus definitions from the Kaspersky Servers.This helps in keeping your recue disk up date without having to download a lot of files, saving a lot of time and bandwidth.

Changes in the latest version

  • Supports updates from Local Kaspersky Folder if you have any Kaspersky Product Installed.

  • Removed pauses in script

  • It doesn`t work with KRD, the databese corrupted. Has anybody use it ad had positive result.

  • Every disk I attempt to build produces the “9abe0003” error, corrupt definitions.

  • Thank you, very useful.

  • After showing succesfull burn.When i run for give me following error

    live-rw does not exist

  • So far, (20140916) I have updated my kav_10.0.32.17 rescue cd without any problem. After updating it, I burned the iso file and worked fine with definitions updated.

  • Today I updated my KAV rescue cd without any problem. I burned the iso file and worked fine with virus definitions updated. See my previous post to donwload the iso file from the link I mentioned previously.

  • I followed the method outlined in the tutorial and i get 25 MB file named rescueusb.iso.
    Which doesn’t make sense. The online update of Kaspersky Internet Security 2014 is 158 MB.
    How on earth will a 25 MB updated file do.

    Better follow this.:

  • I get the databese corrupted and also get a 25MB file.

  • Dude if you’re stupid wake up!

    The manual method and the Kaspersky USB Rescue Disk Maker (that’s the complete name of the tool BHARAT linked here both are based of grub4dos.

    In fact these two methods do the same thing, one manually, not for beginners, that is prone to errors and one automatically using Kaspersky USB Rescue Disk Maker, that works flawlessly every time.

    If you look on the usb flash drive after using the Kaspersky’s tool you will also see inside the \rescue folder 2 files: rescue.iso and rescueusb.iso.

    These two *iso files are connected one with each other using grub4dos’s chainloading property. Both are needed for Rescue Disk 10 to work off the flash drive.

    I hope that helps your ignorance.
