Microsoft has released the beta version of Microsoft Standalone System Sweeper Beta. You can find more information and both the x86  and x64 versions to download over here on the connect site.

I know that all our environments and clients are well protected, patched, and maintained but unfortunately this is not the case all over the board. So this tool can help you to address malware issues.

Microsoft describes the product as follows:

A recovery tool that can help you start an infected PC and perform an offline scan to help identify and remove rootkits and other advanced malware. In addition, Microsoft Standalone System Sweeper Beta can be used if you cannot install or start an antivirus solution on your PC, or if the installed solution can’t detect or remove malware on your PC.

Microsoft Standalone System Sweeper Beta is not a replacement for a full antivirus solution providing ongoing protection; it is meant to be used in situations where you cannot start your PC due to a virus or other malware infection. For no-cost, real-time protection that helps guard your home or small business PCs against viruses, spyware, and other malicious software, download Microsoft Security Essentials*.

To get started, please make sure that you have a blank CD, DVD, or USB drive with at least 250 MB of space. Next, download and run the tool – the tool will help you to create the bootable media required to run the software on your PC.

Yet another tool in your box. Happy hunting and if you do use it, please provide your feedback via the connect site. It only helps make the product better.
