You must prepare a System Sweeper boot device before you actually need it. Rather, it is a last-resort recovery tool for occasions when Windows or traditional anti-malware protection cannot be started or cannot find the source of an infection. The program, called Microsoft Standalone System Sweeper, is not intended as a replacement for real-time anti-malware protection such as McAfee, Avira or Microsoft Security Essentials. It can also find and eliminate hidden rootkits.

Microsoft has a released a beta (test) version of a recovery program that can boot from CD or USB flash drive, allowing users to clean infected machines without loading Windows or depending on your anti-virus software. Some malware can render Windows-based anti-malware programs impotent, or even prevent the operating system from loading at startup.
