Here is a simple (simple for professional) tutorial on how to remove virus, Trojan, and worm without installing an antivirus software onto Microsoft Windows. These simple software are known as bootable antivirus because they are useful when your system is not boot-able. A must have tool if you suspected there is a deeply embedded virus in your root system that is stealing your personal information such as credit card numbers.
How to Use these Tools
First, you’ll need another computer to download the free software, once you are done, install it onto a USB thumbdrive. Make sure your desktop or laptop is set to first boot via USB and not the hard disk. Restart your computer and let the software perform the magic. Alternatively, you can boot via F8 into safe mode to run the portable antivirus.

Kaspersky Rescue Disk 10 is designed to scan, disinfect and restore infected operating systems. It should be used when it is impossible to boot the operating system. Kaspersky Rescue Disk 10 is designed to scan and disinfect x86 and x64-compatible computers that have been infected. The application should be used when the infection is so severe that it is impossible to disinfect the computer using anti-virus applications or malware removal utilities (such as Kaspersky Virus Removal Tool) running under the operating system.
In this case, disinfection is more efficient because malware programs do not gain control when the operating system is being loaded.
