Abstract
Systems and methods for scanning files for pestware on a protected computer are described. In one variation, when a file on a storage device is inaccessible via an operating system of the protected computer, a listing of a plurality of pointers for the file is located on the storage device. Each of the plurality of pointers in the listing points to a corresponding one of a plurality of locations on the storage device, and the storage device stores each of a plurality of portions of data for the file at a corresponding one of each of the plurality of locations. One or more of the plurality of portions for the data are accessed and analyzed, while the operating system continues to limit access to the file via the operating system, so as to determine whether the file is a pestware file.
