This is a tool that will protect you from the recently discovered Windows shortcut problem, where the shortcut file can be modified to run malicious code on your system. This affects ALL versions of windows, old and new. There is currently no real fix for this (other than disabling all/most of your icons on your computer so they just show up as white squares) and there are confirmed attacks out there using this issue today. This tool is a clean install/uninstall so when Microsoft does fix the issue you can uninstall this tool.
The tool basically checks links in shortcuts before it is passed on to the operating system and prevents the malicious code from executing if it exists. You can read more details about the tool at the
Sophos site and you can read more about the exploit on
Security Now! Episode #258
