Okay, I solved this myself after finding a couple other posts regarding this same issue.
It was the Response Body filter rule for the 'Bogus Google Toolbar' that I had enabled in the HTTP filter following the directions from this site for it(http://www.isaserver.org/articles/2004fakegoogle.html). Removing the rule for the Response Body allowed me to download the tar.gz file successfully.

I think this is an issue with 'Byte Range' or 'Format: Text' rather than any specific signatures.
I recently downloaded and installed the block filter settings from www.toolzz.com
For instance I currently have MS04-013-1 and MS04-013-2 in my signatures, when both are enabled I cant access the iTunes Shop, however if I disable MS04-013-2 the iTunes Shop opens fine ... looking closely at MS04-013-2 it has 'Format: Text' and a 'Byte Range' of 1-100 as do the majority of the other signatures.
I'm not sure why this would be ... so over to Tom?
