A bad malware infection will ruin your day. A really bad malware infection will ruin your day and hack your OS, making it nearly impossible to remove conventionally. Luckily there are numerous free software tools you can use to try to clean up a badly infected system, potentially saving you the data loss involved in a full, scorched earth reformat and reinstall. Today, we'll take a look at Kaspersky Lab's Rescue Disk 10, a free live disk tool that comes with Kaspersky's security software.
Kaspersky Rescue Disk 10 is a free live disk utility that you can use to bypass a badly infected operating system, booting its own clean, stripped down OS and allowing you to run the Kaspersky antivirus software unmolested by malware. Rescue Disk is available for download as an .iso image file which you can burn onto a CD, DVD, or USB thumb drive.
After downloading the image file (kav_rescue_10.iso), the first thing you'll need to do is to burn the image onto a disk using any of a number of programs such as Nero, Free ISO Burner, PowerISO, or the Windows Disc Image Burner that comes with Windows 7. The .iso file itself is under 300 MB, so you don't need to waste a DVD or BD if you have a blank CD handy.
An alternative to using a CD or DVD is to mount the Rescue Disk 10 .iso file onto a USB thumb drive. Kaspersky provides a utility to let you do just that. Download the USB Rescue Disk Maker along with the .iso, run the utility, and select a USB stick that you want to turn into a Rescue Disk.
Once you've got your Rescue CD or USB drive ready, plug the disk or drive in, restart your computer, and then configure your BIOS to change the boot order from your hard disk to the rescue disk. Save the new boot order and exit the BIOS so that you can now boot the Rescue Disk.
Once booted, Kaspersky Rescue Disk 10 will prompt you to select a language and confront you with a EULA wall of legalese. Once you agree to the EULA, you'll be confronted with this boot menu. Select the "Graphic Mode" option to boot Rescue Disk with a GUI, or if that doesn't work, use the clunkier text mode. You can also view hardware info about your machine, reboot, or shut down.
Graphic Mode will provide you with a generic GUI. You can then run the Kaspersky Rescue Disk's antivirus scan through the start menu at the bottom left, or by simply doubleclicking the icon on screen.
Once the Rescue Disk's AV suite is up, the first thing you'll need to do is update the virus definitions. Click on the "My Update Center" tab to start the update. The Rescue Disk should autodetect your internet connection and the go from there, but if you need to set up your network connection, then you can configure it from the netwoork connections icon in the bottom right of your taskbar. Once the update is done, click the "Settings" button on the upper right of the window for the next step.
