Filtering Self-Extract archives

Curious,

Is there a decent way to filter self-extracting archives like winzip or
install shield? I’m a little stumped on how
differentiate between an ‘exe program’ file and an ‘exe self-extract’
archive.

One way I think would work would be to use a traditional AV approach and
attempt to locate the stub’s
signature within the archive…

Any creative/better ideas?
