Findexe

<quote> FindEXE for Windows Quickly searches one or more paths and locates
executable files with conventionally non executable file extensions. Such
files may be viruses or trojan programs trying to hide from virus scanners
(e.g. a JPG file which really contains an executable virus). </quote>
