ESET SysRescue Live

ESET SysRescue Live is a free utility that allows you to create a bootable rescue CD/DVD or USB Drive (1GB or larger). You can boot an infected computer from your rescue media to scan for malware and clean infected files.

The main advantage of ESET SysRescue Live is the fact that it runs independent of the host operating system, but has direct access to the disk and file system. This makes it possible to remove threats that under normal operating conditions might be impossible to delete (for example, when the operating system is running, etc.).
