I think this is a normal behaviour... the system check only file names not file content (that can be compressed with upx or other compression system).
In Windows I can't execute anything that has .txt extension....

What are some better methods to find out the file type? There is a command named 'fiile' in *nix systems that does a good job of identifying the same. Here is an excerpt from the man page:

"The magic tests are used to check for files with data in particular fixed formats. The canonical example of this is a binary executable (compiled
program) a.out file, whose format is defined in <elf.h>, <a.out.h> and possibly <exec.h> in the standard include directory. These files have a
‘magic number’ stored in a particular place near the beginning of the file that tells the UNIX operating system that the file is a binary exe‐
cutable, and which of several types thereof."

In this case is useful to check also the archive contents.... I can stop zipped exe/cmd/vbs files ;-)
At the moment it's impossible to do....
