AdSc.7z.002 is part of a multi-volume 7-Zip archive that requires all sequential parts (beginning with .001) to be in the same folder to extract successfully. To open, right-click the first file (.001) using 7-Zip or WinRAR and select "Extract Here" to automatically combine all parts. For a detailed guide on opening split 7z files, see the SourceForge discussion .
