Are Proxy Firewalls a Security Hole?

Given that people are sending larger and larger files, proxy firewalls
seem to be limited since they can't inspect files after a certain
point and the 'stream', 'flow', 'express' AV options of many of the
proxy firewall vendors inspect only a portion of the large file. I've
been able to put the Eicar virus in different locations of a large
test file and successfully get the file through the firewall.

So, are proxy firewalls a security hole?
