disguised .exe files

Hi All

I am running some tests with QS and I may be missing something.

It is blocking ".exe" extension files but if I take this same file and
rename it to ".gif", QS let it pass.

Curious fact is:

Mon, 07 Mar 2011 08:48:49 BRT:4748: found C-T attachment filename "putty_teste.gif"
Mon, 07 Mar 2011 08:48:49 BRT:4748: w_c: attachment  8: Content-Type of image/gif found
Mon, 07 Mar 2011 08:48:49 BRT:4748: w_c: base64 looks like a Windows executable, filename=putty_teste.gif,type=image/gif

As you can see, QS suspect it is a ".exe" file but take no order action.

What am I doing wrong??

Regards

Ethy
