For the rescue CD/DVD/USB to use effectively, you must provide that the computer boots from the ESET SysRescue boot media. Boot priority can be modified in the BIOS. Alternatively, you can invoke the boot menu during the computer startup – usually using one of the F9 – F12 keys depending on the version of your motherboard/BIOS.
After booting up, ESS/EAV will start. Since ESET SysRescue is used only in specific situations, some protection modules and program features present in regular ESS/EAV are not needed; their list is narrowed down to Computer scan, Update, and some sections in Setup. Capability of updating virus signature database is the most important feature of ESET SysRescue. We recommend that you update the program prior starting a Computer scan.
