Created by Daniel Pistelli, a freeware PE identifier. This tool was originally designed to be part of the Explorer Suite II, but it can be downloaded separately as well. The PE Detective can scan single PE files or entire directories (also recursevely) and generate complete reports. The PE Detective is deployed along with the Signature Explorer, which is an advanced signature manager to check collisions, handle, update and retrieve signatures.
To scan a file is very easy with the PE Detective tool: just drag & drop a file on the interface and press scan. If there are multiple results, all of them will be listed in descending priority. The data for each result shows the signature name, the number of matches (meaning how many bytes in the signature match, wildcards aren't counted) and possible comments regarding the signature.
