The process of 'opening' isn't built into outlook, hence the
problem. The same thing happens for an outlook attachment
as would happen to a file. When you double-click it, the
handler registered for that file extension executes. If winzip
is installed and has registered itself as the handler for
tar (and I think it does), then a tar attachment will open
automatically just like zip. Likewise for any other type - if
you have a handler, outlook will run it. In old/unpatched versions
of outlook this is even worse. Some file types are processed
automatically in the preview pane, like playing sounds. The
old bug used the Mime content-type header to decide when to
run something automatically but the file extension to decide
what handler to run...
