License agreement on the terms of use of the Dr.Web LiveDisk software. Bootable antivirus disks and flash drives
Well, if you've landed on this page, it means things are really bad. It often happens that it is no longer possible to fight the virus from the operating system. And you already need to solve the problem with your computer by booting from the BIOS. Rootkits, spies, SMS banners and other harmful evil, they won’t surrender to you that easily.
can become a formidable weapon against viruses.
All the most popular antivirus developers provide the opportunity to use their antivirus utilities as part of a boot image, both for writing to a disk and for writing to a flash drive. But I'll focus on creating a bootable USB flash drive ESET-Live - USB . As you probably already understood, this is an antivirus.
Nod32 -
Download the program to create a flash drive with antivirus
After you download the program to create a bootable USB flash drive with antivirus, you have to do a few simple manipulations.
you have, but we also need a boot image and when starting the utility, first of all, download it.
At the next stage, when we already have a boot image with nod32, select its location on the computer and indicate the USB drive on which you want to write files to boot from the BIOS. All that remains is to click on the “Create USB” button.
We are waiting for the bootable USB disk to finish burning. The flash drive is ready! But you don't know what to do next? On the pages of this site I have already told -. After setting up the BIOS correctly and then rebooting the computer, you will see this screen. It is preferable to select the first item “graphics mode”. If the shell does not boot, reboot and try the second line “copy to RAM”. After a successful download, you will be presented with a desktop on which there is a tool for
scanning your computer for viruses "ESET SysRescue" There is also a utility for removing the so-called banner, which typically disables the task manager and locks the registry. And its main feature, which cannot be ignored, is a banner on the entire desktop, requiring you to send a message to a number in order to pay a fine for some mythical violation of the law. Naturally SMS is paid! But even if you send a message, the banner will not disappear.
It’s very easy to work with the anti-banner program, just run it and then it does everything itself. Bootable USB flash drive with node32 Suitable for most computers, but of course there are exceptions. And you can just as easily write to flash drive boot image with other rescue software. If you still have questions after reading or have any questions during the process of creating a flash drive and subsequent work with it, ask them in the comments, I will definitely answer.
Malicious programs cause a lot of trouble for computer users, especially beginners - they often become unwitting victims of virus epidemics that nullify the performance of electronic computers. In such emergency situations, some PC owners turn to IT professionals for help, while others, more experienced and confident in their abilities, use emergency anti-virus boot disks, a brief review of which is the subject of this article. The solutions under consideration allow you not only to clean your computer from ransomware Trojans, infected and suspicious objects, but also, in case of urgent need, to copy important files to removable drives or another PC. An important fact is also that all of them (with rare exceptions) are free and developed not just by anyone, but by renowned anti-virus companies that know a lot about information protection and computer security. And one last note: since almost all system emergency recovery disks are presented in ISO image format, their use is possible only after extracting and burning the files onto optical media, which can be prepared using the appropriate CD and DVD burning tools.
Kaspersky Rescue Disk 10 (196 MB). A development by Kaspersky Lab, based on the Linux platform and featuring an interface translated into 20 languages, stylized to resemble the Windows familiar to many users. In addition to the virus scanner, the product includes the Xfe file manager, the Firefox browser, utilities for setting up a network and taking screenshots, as well as help documentation. For command line experts, there is a terminal that gives access to a console that is black as night. According to information provided by Kaspersky Lab specialists, Kaspersky Rescue Disk is designed to scan and disinfect infected x86- and x64-compatible computers. The program is used when the level of infection is such that it is not possible to cure the PC using anti-virus solutions running under the installed operating system. At the same time, the effectiveness of treatment is increased due to the fact that malware located in the system does not receive control while the OS is loading. You can burn the image of the emergency recovery disk either to a CD/DVD or to a flash drive. The corresponding instructions are published on the developers' website.
Dr.Web LiveCD (136 MB). A software product based on the Dr.Web anti-virus scanner and also available in the LiveUSB edition. The solution comes in the form of a boot disk with a Linux-based operating system and built-in software designed to scan and repair your computer, work with the file system, view and edit text files, browse web pages and conduct email correspondence. With a view to reaching a wide audience, the Dr.Web LiveCD interface is presented in English; for users experiencing “translation difficulties,” Russian-language documentation is provided that reveals all the intricacies of working with the anti-virus product.
BitDefender Rescue CD (319 MB). An impressive size toolkit presented in five languages - English, German, French, Romanian and Spanish. Linux is used as the boot environment, stuffed, in addition to the BitDefender antivirus scanner, with many useful utilities, among which Gparted, designed for managing disk partitions, and TestDisk, which in capable hands provides recovery of boot sectors and data, deserve special attention. The latter program can also be useful for analyzing a non-bootable storage medium and subsequently transmitting the results to technical support.
Avast! BART CD (134 MB). Antivirus emergency disk, distributed commercially for $150 per copy and, at the free will of the developer, available for free testing for 14 days. You cannot download the product right away: you must first fill out a special web form and wait for approval from AVAST Software representatives. In our case, waiting for the treasured news with a registration key and a link to download the program distribution took about a day and a half. The mention of the word “distribution” is no coincidence: building an ISO image of Avast! BART CD is carried out using a proprietary installer, which first downloads all the necessary updates from the Internet and packages them into bootable media format. Being built on the basis of Windows PE, the development of the Czech team is “sharpened” exclusively to restore the functionality of computers running Microsoft operating systems. To resurrect a PC, the disk contains an antivirus, a registry and Windows system services editor, network utilities, disk management programs, a file manager, as well as tools for removing and reinstalling conflicting drivers. Functional content of Avast! BART CD is implemented at a decent level, and the only thing that can scare away potential users of this solution is its cost.
F-Secure Rescue CD 3.11. (118 MB). A text interface, a complete lack of settings and a terribly slow module for updating signatures that comes with the antivirus disk - these are the main features of this solution, built on the Linux platform and raising more questions than delight. The development is clearly designed for those users who know how to remain calm in any situation, are willing to put up with an ascetic interface, or are fans of the products of the Finnish company F-Secure. The description of Rescue CD 3.11 includes tools for working with the file system and restoring deleted or damaged data, but it is not possible to get to it due to the lack of corresponding items in the program menu. In general, not for everybody.
Panda SafeCD (215 MB). Another Linux build, made in the style of severe minimalism and offering a single tool for resuscitating a computer - an antivirus developed by Panda Security. Neither a browser for searching technical documentation on the Internet, nor a file manager for retrieving surviving data from a PC disk, nor any other utilities are provided in SafeCD. But the product of the Spanish company can boast of a graphical interface, implemented in the form of a step-by-step wizard that helps the user carry out certain operations.
Avira AntiVir Rescue System (77.4 MB). The creation of the hands of German programmers, endowed with an intuitive interface that will not be difficult to understand even for users who do not know the overseas language. The product includes an anti-virus scanner equipped with a module for treating infected objects, and a Linux console, using which you can launch the Midnight Commander file manager and other utilities provided in the operating system. It would be logical to place a shortcut to launch the same MC in the main window of the boot disk, but for some reason Avira specialists chose not to do this. However, they know better.
AVG Rescue CD (80.5 MB). A software product built on the Linux code base and providing the user with a fully working AVG antivirus solution for scanning various file systems for the presence of malicious code. This is the first point. There is also a second one: the disk contains the Midnight Commander file manager, the Windows registry editor, a utility for checking connections in TCP/IP-based networks, as well as the TestDisk and PhotoRec applications for data recovery. Among other things, the AVG Rescue CD provides a text browser called Links, which will serve you well when solving complex issues that require the support of network intelligence. In general, we recommend it.
Live CD Vba32 Rescue (114 MB). A boot disk for emergency system recovery after a virus infection, based on Linux and created by the efforts of specialists from the VirusBlokAda company. Characteristic features of this solution are a text interface translated into English, Russian, Belarusian and German, a console anti-virus scanner, a Midnight Commander file manager and a network settings module for accessing the Internet and updating signature databases. Vba32 Rescue supports an image loading mode into memory, which allows you to scan multiple computers in parallel using one bootable CD or USB drive. Details about the process of creating and deploying an ISO image to a flash drive are described in the documentation included with the product.
Norton Bootable Recovery Tool. Emergency recovery disk produced by the famous Symantec corporation. It is implemented on the basis of Windows Vista PE and for this reason it is very hungry for the computer’s system resources, requiring at least 1 GB of RAM to run. At startup, it displays a window with a form for entering a registration key for any product in the Norton 2010/2011 line, which significantly limits the circle of potential users of the anti-virus solution. We didn’t have the treasured key at hand, and we weren’t able to see with our own eyes the tool created by American programmers that “eliminates the most terrible computer problems” (literal quote from the developer’s website). Norton Bootable Recovery Tool is distributed as a 371 KB installer that downloads files from the Internet and creates an ISO image of 422 MB in size! Such an impressive size definitely hints at the powerful potential of the product, which, alas, can only be used by a select few.
Every month, tens (if not hundreds) of thousands of new malware are born, the evolution of which spurs the development of tools and methods to combat digital infection. A prime example of this is the rescue disks mentioned above. Already, most of them are equipped with utilities for transferring to USB drives and subsequent use in the now so popular netbooks and subnotebooks. In addition, many of the solutions discussed are able to interact with WiFi adapters and provide a rich toolkit for restoring PCs that have lost functionality as a result of the destructive actions of viruses or incorrect user manipulations. The choice of means to combat the digital disaster is huge. We recommend that novice computer owners pay attention to the domestic developments Kaspersky Rescue Disk and Dr.Web LiveCD; IT industry experts are advised to take a closer look at more advanced solutions, such as Avast! BART CD and AVG Rescue CD.

Some malware cleverly bypasses antivirus protection and integrates itself deeply into the system. In this case, detecting and removing the virus becomes quite a difficult task. In such a situation, it may be advisable to use a Rescue CD. Antivirus boot disks can help you recover your system by removing infections that cannot be removed by antivirus software.
Antivirus boot disks will scan for and remove computer viruses without having to boot into your computer's operating system. Most bootable versions of Rescue CD tend to be based on Linux Live CD. The system is easy to scan for malware without writing system files on your hard drive. Some of them use DOS or a DOS clone, FreeDOS, some use a stripped down version of Windows called Windows Pre-Installation. Rescue CDs are usually available at. ISO format, you can burn an ISO image to a CD/DVD using any program for burning optical discs, for example, Nero Burning ROM, ISO Recorder, DeepBurner, Roxio Creator or the completely free program DAEMON Tools Lite.

One of the reasons for the inability to start the Windows operating system is the penetration of malware into the computer. Ransomware Trojans, for example, can block logins and demand money to unlock them. Windows may not boot due to viruses damaging important system files. Another example is that Windows boots successfully, but the malware blocks the launch of an antivirus, portable antivirus utilities, backup programs, the standard functionality of Windows rollback to a restore point, and other tools that could solve the problem. For all these and similar emergency cases, there is only one solution - the use of an emergency boot Live CD with an antivirus on board.
Below we will look at five emergency Live CDs from the creators of popular antiviruses. But first, let’s briefly talk about the essence of anti-virus live CDs.
Emergency boot Live disks from the creators of antiviruses
Live CD, which translated means “live disk,” is a bootable CD/DVD, flash drive, or even, if you want, an external hard drive with certain content, capable of working autonomously, based on its own platform. Special Linux distributions and WinPE, a lightweight version of Windows, are often used as such platforms. Not all antivirus product makers offer Live CDs, but many do. Anti-virus “live disks” naturally include an anti-virus scanner, and in most cases also auxiliary tools such as: a utility for accessing the system registry, a browser for searching information on the Internet, a file manager for rescuing important data, etc.
The anti-virus Live CD distribution is downloaded (usually for free) on the official website of the security software developer. Then the distribution package downloaded in ISO image format is written to a CD/DVD disc or flash drive. Some antivirus developers, in addition to the ISO image, additionally offer special utilities for downloading that can create bootable flash drives with the contents of the rescue disk. After burning to a blank or flash drive, the finished Live CD is set to BIOS boot priority, and the computer boots from it, and not from damaged Windows.
It is better to create a Live CD in advance. Even if Windows with malware in full swing is able to boot, it is not a fact that the process of creating a “live disk” will be successful. When malware prevents an antivirus installed on a system from launching, this process is often accompanied by blocking the web resources of antivirus software developers so that users cannot download antivirus utilities or rescue disks. In this case, as well as in the event that Windows is unable to boot if the Live CD is not prepared in advance, an additional computer will naturally be required.
Well, now, actually, about specific Live CDs on today's security software market. Antivirus developers offer the five below for free.
1. Kaspersky Rescue Disk
Kaspersky Rescue Disk - an emergency LiveDisk based on Gentoo Linux from an old-timer in the security software market, the Russian Kaspersky Lab - can be downloaded in ISO image format from the official website at the link:
Kaspersky Rescue Disk provides a choice of language, text and graphical interface.
This Live CD is equipped with a browser, a file manager, and a Windows registry editor. It is possible to update anti-virus databases. Before running an anti-virus scan, you can specify the areas to be scanned.
When completed, the scanner will provide a report.
Kaspersky Rescue Disk provides a full-fledged anti-virus scanner settings section. In the settings before scanning, you can set the security level, action when threats are detected, and add exceptions.
2. Dr.Web Live CD
Another Russian developer of anti-virus software, the no less well-known company Doctor Web, also has among its products a Live CD based on Gentoo Linux – Dr.Web Live CD. Separately in ISO image format and separately in the format of a utility that writes a bootable USB flash drive, Dr.Web Live CD can be downloaded from the official website using the link:
The Dr.Web Live CD tools include a RAM diagnostic tool, a utility for editing the system registry, updating anti-virus databases, access to the Internet via the Mozilla Firefox browser, two file managers and an anti-virus tool in the form of the Dr.Web CureIt! utility. Before running it with default settings, you can select the areas to scan.
After checking Dr.Web CureIt! will provide a report where, in addition to the possibility of applying a single solution to all detected threats in the form of a treatment attempt, for each threat separately you can select another action - moving to quarantine or deleting.
Dr.Web Live CD also provides a configuration section as part of the Dr.Web CureIt! utility, where you can configure its automatic actions when each individual type of threat is detected, and add individual folders and files to exceptions.
3. Zillya! LiveCD
Built again on Linux LiveDisk from the creators of the Ukrainian antivirus Zillya! will offer a RAM diagnostic tool, an anti-virus scanner, two file managers and Internet access. ISO image of Zillya! LiveCD separately and a separate utility for burning it to a flash drive can be downloaded on the official antivirus website at the link:
Antivirus scanner included in Zillya! LiveCD provides fast, full and selective scanning.
The scanning process cannot be customized. All that will be available after the scan is completed is the ability to remove detected threats.
4. Avira Antivir Rescue System
Another Live CD based on Linux, this time Ubuntu - the product Avira Antivir Rescue System from the Germans, creators of the well-known Avira antivirus. On the official website Live CD can be downloaded in ISO image format and utilities for burning CD/DVD discs, link to a specific page:
Working with the Avira “live disk” will differ from all previous options in its attractive and user-friendly interface - a legacy of Ubuntu, as well as functionality. This is the most functional Live CD of all the other participants in the review. The Germans took a responsible approach to the issue of creating an emergency disk and thought through more options for emergencies. Thus, the LiveDisk assembly from Avira provides for launching diagnostics of RAM and hard drive at the boot stage. Directly in the Antivir Rescue System environment, you can access data in the file manager, access system registry entries in the Avira Registry Editor utility, and access the Internet using the built-in Mozilla Firefox. You can even establish a remote connection using TeamViewer and work with disk space allocation within the GParted utility. You can start an anti-virus scan of your computer in the welcome tab of the Avira application.
You can select individual disk partitions as scan areas.
The scan completion window will provide a report showing the number of files scanned, threats detected, and files renamed. A detailed report on the work performed can be obtained by clicking the “Report” button.
In the report we will get the names of the threats, the path of placement and a note about the file renaming. It is better to save the scan results report.
The fact is that the Avira anti-virus scanner included in the Live CD, when detecting threats, does not delete problematic files, but renames them to neutralize them. This is a kind of protection against false positives. In the future, using the report data, the necessary files can be returned to their original state, and the malware files can be deleted.
Avira's Live CD does not provide the ability to configure a virus scanner.
5. Avast Rescue Disk
The WinPE-based rescue disk from the Czech company Avast Software only contains the ability to work autonomously from removable media among the features of a Live CD. Having booted from it, we will not have access to the Internet, we will not see the file manager, we will not find other utilities for emergencies. At the same time, Avast Rescue Disk is an ideal tool for beginners, offering only an antivirus tool that is simply impossible not to understand how to use, due to the simplicity and convenience of the interface, as well as the absence of various distracting utilities. Avast provides for the creation of a rescue disk inside the desktop antivirus. Free Avast antivirus for installation on Windows can be downloaded from the link:
In the “Tools” section of the antivirus installed on the system, the process of creating a rescue disk will be available.
Avast will help you burn a Live CD to a disc or offer to create an ISO image for a bootable flash drive.
After downloading Avast Rescue Disk, we will see a single anti-virus scanner window offering a choice of scan areas - the entire computer, individual disk partitions or folders.
Based on the scan results, we will receive a report on the number of scanned and infected files, which will suggest the use of automatic correction. This means that Avast will first try to treat infected files, and if efforts are in vain, it will delete them. We will get access to managing detected threats by clicking the “do it manually” button.
By selecting each individual file, you can apply the same automatic correction to it, delete it, or restore it if it was a false positive.
Have a great day!
Antivirus boot disk This is a disk with an operating system, mainly based on the Linux kernel, respectively, an antivirus program and other auxiliary programs and utilities. Why was the Linux operating system chosen? Because, due to their differences, viruses and malware for the Windows OS do not work (and cannot even theoretically work) in the Linux environment. Secondly, you don’t need to pay to use Linux source code in your developments.
You can download a boot disk mainly as an ISO image. Some people mistakenly just burn the file to a CD and then complain that nothing works. To burn a disk image, you need a special program that will unpack and burn it to CD. For this purpose, you can use the popular Nero program.
When used, a boot disk or flash drive is inserted into the computer and the computer starts from it. To do this, you need to reconfigure the BIOS to start the computer first of all from external media CDs or flash drives, and secondly from the hard drive. Starting the operating system from the disk may take some time depending on the speed of the CD drive or the amount of RAM. When the contents of the disk are fully loaded into RAM, the operation of the boot antivirus will be much faster. In this article we will look at the three most popular anti-virus boot disks.
Dr.Web LiveCD or a similar anti-virus for the Dr.Web LiveUSB flash drive is designed for emergency treatment of a computer without the need to start the operating system.Doctor Web antivirus on disk can completely scan your computer. If you have an active Internet connection, you can update your anti-virus databases to improve scanning efficiency.
Kaspersky Lab has its own anti-virus boot disk called . It similarly has a Linux platform and an antivirus scanner. You can also update virus definitions if you have an Internet connection.
It works on a similar principle. It is possible to run the antivirus from the command line without starting the graphical operating system.
Many more antivirus developers have free bootable disks. They all have a similar principle of operation, differing only in anti-virus scanners.
