In past there was plugin
EPScan for PEiD (should be compatible with Exeinfo), that can simplify your work:
Code:
https://mark0.net/plugins-peid-epscan-e.html
EPScan add the ability to scan a serie of executable files and detect common patterns in the firsts 128 bytes of code at program entry point. This way, the process to create a new signature for a specific type of EXEs is greatly simplified. Running the plugin will trigger the scanning of all EXE files in the same folder of the currently selected one. In an instant a dialog box will show the extracted common bytes. As the format used is the same of PEiD's USERDB.TXT external signature file, it take just some cut & paste to quickly add the brand new signature.
or
Signature Maker for 32 and 64 bit exe files
You can create your sign. for Advanced Scan plugin ( userdb.txt )
