Dr.Web live disk: how to use, what is it for

Dr.Web LiveDisk is an emergency disk for treating and restoring the Windows operating system in cases where the computer starts with failures or is not possible at all. The emergency “live” disk Dr.Web LiveDisk was previously called Dr.Web Live CD (Dr.Web Live DVD) or Dr.Web Live USB.

After loading the Dr.Web Live boot disk from a CD/DVD disk or from a bootable USB flash drive, you can take the necessary steps to treat and restore the system. Booting from external media, the so-called Live CD, will help solve problems and cure the system, even if Windows fails to boot.

The Dr.Web LiveDisk boot disk, in addition to treating and restoring damaged system components, can be used to delete undeletable files, to copy important information to another drive (external hard drive, flash drive), if there are doubts about the possibility of restoring Windows, to delete unnecessary files and so on.

The Dr.Web Live Disk disaster recovery system is based on the Linux operating system.

You can download the Dr.Web LiveDisk emergency boot disk from the official website of the famous Russian anti-virus company Dr.Web.

Download Dr Web Live

On the download page, in the “Sysadmin First Aid Kit” section, select the type of bootable media, depending on the configuration of your computer (no or not a CD/DVD drive):

“Download to burn to CD/DVD.”
“Download to record to USB.”

After clicking on the appropriate item, accept the terms of the license agreement. Immediately after this, the download of a disk image in ISO format for a CD/DVD disk, or a special Dr.Web application in EXE format for creating a bootable USB drive, will begin.

After burning Dr.Web LiveDisk to a flash drive or CD/DVD disk, you will have an emergency recovery disk for treatment and system recovery, or for saving user data if it is impossible to restore normal operation of Windows.

Burning a Dr.Web LiveDisk boot disk to a CD/DVD disk

To burn a Dr.Web LiveDisk disk image to a CD or DVD, you must use the system's disk burning tool, which is available in the operating systems Windows 7, Windows 8, Windows 8.1, or any disk burning program, for example, Ashampoo Burning Studio, ImgBurn, CDBurnerXP, etc.

In the appropriate application, select the Dr.Web LiveDisk CD image, and then burn it to an optical DVD or CD by selecting the “Burn image” option.

After recording, you will have a bootable Dr.Web LiveCD.

General description of the toolkit

We must give Dr.Web its due - the developers are tirelessly working to improve their antivirus and develop new options for combating any Internet infection. This happened this time too, namely they released a certain LiveCD which will actually be discussed in this article.

Although, if someone is too lazy to read, then we have a visual video format:

If it is inconvenient for you, then you can continue studying the article with pictures and everything else.

What kind of LiveCD is this? It is a shell (i.e., something like a stripped-down version of the operating system) based on Linux, into which a number of programs are built in (Mozilla FireFox and other varieties) and, in fact, the antivirus itself.

This miracle, being written to a disk and launched from this disk using the BIOS, boots as a separate operating system (without any installations) and allows, as I already said, to restore the functionality of a system affected by viruses on workstations and servers running Windows \Unix, and also, importantly, copy important information to removable media or another computer if the actions of malicious programs made it impossible to boot the computer.

Creating a bootable Dr.Web LiveDisk on a USB flash drive

Connect the flash drive to your computer by inserting the flash drive into the USB port. Run the Dr.Web LiveDisk USB file on your computer.

In the “Dr.Web LiveDisk” window, select the USB drive. It is recommended to check the box “Format the drive before creating Dr.Web LiveDisk” in order to delete all data from the flash drive before recording.

Next, files will begin to be copied to the bootable Dr.Web LiveUSB flash drive.

After the process is completed, you will see a message in the application window stating that the emergency recovery disk has been created on the USB drive. Click on the "Exit" button.

Complete instructions for Dr.Web LiveUSB: create, download, scan

There are cases when malware blocks the system, extorting money from the user, or damages system files so much that it is no longer possible to boot. This is where a powerful tool from Dr.Web comes to the rescue - Live USB, which can be written to a flash drive, booted and disinfected Windows. Here are complete instructions for using the Doctor Web bootable flash drive.

How to use Dr.Web LiveUSB?

The Doctor Web healing flash drive allows you to restore operation of an infected system from which it is impossible to boot. If viruses or other malware have damaged system files, then using Dr.Web LiveUSB (LiveCD - written to disk) you can boot from a flash drive and cure the OS, remove malware and try to restore important files.

How to download Dr. Web Live USB?

I'm sure you've come across websites where you can download Dr.Web Live USB from a torrent or some file hosting service - you don't need to do this! Download only from the official Dr.Web website, all further instructions will be based on the example of the official website.

And so, go to the Dr.Web website, and more specifically to the Doctor Web library of free utilities, here - https://free.drweb.ru/

On the top panel you need to click on Dr.Web LiveDisk

The Dr.Web LiveDisk page will open with a choice for downloading - LiveCD or LiveUSB. Select the second item - to record to a USB drive (LiveUSB).

In principle, there is no difference here, it’s just that a LiveCD is an ISO image that can also be written to a flash drive. But the second option (LiveUSB) is an EXE file, by running which it will be easier to install it on a flash drive automatically, without using third-party programs (such as UltraISO), as, for example, for LiveCD.

From the previous paragraph it became clear how these two files differ, and I think everyone chose LiveUSB, unless, of course, they firmly intend to write the antivirus to a flash drive and not to a disk. Next, you need to accept the license agreement to download the utility, scroll down the page and click on the button.

Next, wait for the Dr.Web LiveUSB utility to download.

Installing Dr.Web LiveUSB on a flash drive

Now, finally, the file for installing Dr.Web LiveUSB on a USB flash drive has been downloaded. Some points need to be taken into account before you start recording the antivirus utility onto a USB drive:

Your BIOS should support booting from USB-HDD (most likely there will be no problem with this)

In new computers, UEFI is replacing the BIOS, and the problem is that you can’t just boot into UEFI from a flash drive. If you have UEFI, then a little further you will find a detailed solution to this issue, for now follow the instructions.

Now let's move on.

We connect the flash drive to the computer, if there are important files on it, they need to be transferred to another location, the flash drive will be formatted..

Launch our downloaded Dr.Web LiveUSB utility. The utility installer window will open. In the drop-down menu, you must select the flash drive on which Doctor Web Live will be recorded.

Below, check the box “Format the drive before creating Dr.Web LiveUSB”.

Click the “Create Dr.Web LiveUSB” button. We agree with the warning about formatting the drive.

We are waiting for the process of downloading the utility to the flash drive. This will take some time. Further after the end, you will be notified about this.

Download from Dr.Web LiveUSB

Now, finally, we have reached the point of loading the computer with Doctor Web Live in our instructions. Now you need to make sure that the computer boots from a USB drive, and not from the HDD where the system is installed.

Insert the flash drive into the USB port of the computer/laptop and turn off the computer.

Now we need to enter the BIOS, how to do this is written in detail in this article. Usually this is the Del, F1, F10 key on the keyboard. There may also be combinations with the Fn key (often found on Lenovo laptops). Immediately after turning on, press this key or combination (it is better to press it many times and quickly before the system has time to boot).

Next, once you have entered the Bios, you need to find the item responsible for booting the computer from a USB device. Also, there is a detailed article on how to boot a computer from a flash drive. In short, we find the desired tab, usually “Boot”, and put USB in first place. That's it, press F10 and wait for it to load. If this happens, then it is better to put the HDD back in place, in the same way as above, naturally after finishing working with LiveUSB.

In most cases, when you start your computer, you can simply press the boot selection key (usually F12) and select from the list the device from which you want to boot (USB drive). In this case, you will not have to return anything, subsequent downloads will be the same as before (from the hard drive).

For those with UEFI

Booting from a flash drive is not as easy to do on new UEFIs as it can be done in old BIOSes. Therefore, you will have to disable the Secure Boot feature.

How to find out if a laptop has UEFI? And is Secure Boot enabled?

It's simple. Press the Windows key combination - Ctrl + R, type msinfo32 and press Enter.

Now look at the line “BIOS mode”, if there is UEFI, then you have a new BIOS. Now look at the line “Secure Boot Status”; if “disabled”, then the Secure Boot function is disabled in the BIOS of your laptop.

What to do if Secure Boot is enabled? We won’t go into depth here, this is a separate topic, here are detailed instructions for disabling Secure Boot in UEFI.

Now, we have completely figured out how to boot from Dr.Web LiveUSB on a computer or laptop, be it the old Bios or the new UEFI. Now let's move on to the instructions for using the Doctor Web boot utility.

Downloading Dr.Web LiveDisk on your computer

Set the BIOS to prioritize booting from USB or from a CD/DVD drive, depending on what type of boot disk from Dr.Web you are using. To be able to load Dr.Web LiveDisk on computers with UEFI, you must enable Legasy mode.

After loading the rescue disk, a window will open with a choice of boot options:

Web LiveDisk - downloading the emergency disk Doctor Web Life Disk.
Test memory - test memory using the Memtest86+ utility.
Boot from first hard disk—exit Dr.Web LiveDisk, boot the operating system from the hard drive.

Switching between modes is done using the keyboard arrow keys.

By default, the DrWeb live disk window has an English interface language. To switch to Russian, press the “F2” key, then press the “↓” arrow key, and then press the “Enter” key.

Next, the configuration will begin in accordance with the hardware of this computer. Wait for the Dr.Web LiveDisk working environment to load.

DR.Web_LiveUsb

To install, download
the iso
image from the site ftp://ftp.drweb.com, write it to a disc, and start the computer from the disk.

1. When loading Dr.Web LiveCD

from the disk in the mode selection dialog box, specify the item:
DrWeb-LiveCD (Safe Mode)
or
DrWeb-LiveCD (Safe Mode no ACPI)
.

2. Dr.Web LiveCD

will boot in command line mode.
From the main menu, select Start Shell
.

3. To check the disks connected to the computer, run the mount command: /bin/mount

or just
mount
4. Connect the flash drive and check the connected drives again. A new disk will appear in the list, let's say it will be designated /dev/sda1

5. Run the create_usb command: create_usb sda1

For this operation we use another flash drive formatted in fat3

I’ll explain why this is so: if you stupidly copy it directly from a CD, it won’t work because it requires a disk when loading and that’s it…. Apparently something is written in the kernel

let's continue... Then copy the boot

and rename it to
Dr.Web
, then you need to create a menu, create the file
/boot/menu/drweb.lst
and enter the following into it:

foreground ffffff background 03bc19

title Dr.Web LiveUSB kernel /DrWeb/vmlinuz root=/dev/ram0 init=/linuxrc init_opts=4 quiet dokeymap looptype=squashfs loop=/DrWeb/module/white.mo usbroot slowusb vga=791 splash=silent,theme:drweb CONSOLE=/dev/tty1 initrd=/DrWeb/initrd

title Dr.Web LiveUSB (Safe Mode) kernel /DrWeb/vmlinuz root=/dev/ram0 init=/linuxrc init_opts=3 quiet dokeymap looptype=squashfs loop=/DrWeb/module/white.mo usbroot slowusb initrd=/DrWeb/initrd

title Return Back <== configfile (hd0,0)/menu.lst

title Reboot reboot

title ShutDown halt

and add a link to this menu to the main menu

title Dr.Web ==> configfile (hd0,0)/BOOT/menus/drweb.lst

All !!!

A few words about use: In order to be able to update the database, you need to do the following: after startup, by default the network is not running, and when it starts, it tries to get an address via dhcp

and often it is necessary to use statics; for those who are familiar with Unix, it will not be difficult to configure, but for beginners it will be very difficult; I will describe what needs to be done; go to the terminal

1) assign ifconfig address 192.168.1.*

2) add the default gateway
route add default gw
3) add the
DNS

/etc/resolv.conf
file , i.e. add the following lines
namesrver
<your dns server> 4) start the network
