Kinda. It depends on what you are testing: whether your AV will put
the kibosh on malicious code or whether it will detect Viruses that
are "in the wild".

You may be a better coder than most virus writers. You could be
innovative where some viri authors are just using a util to disguise
their code. The only way to check to see if your AV will detect what
is out there, is by using what is out there.

Of course if you are testing signature turn around, then you have to
write your own IMO.
 
I just explained why that doesn't work either.  Also, if an AV company
achieves a signature turnaround of one minute, at the expense of QC and
false positive testing, then you'd probably rate them as "Very good",
whereas the thousands of people plagued by the false alarm would rate them
as "Awful".

It is really hard to test AV products. I really would refer you to me 
"Perfect  Antivirus", which is guaranteed, if used correctly, to detect 
all viruses past, present and future 100%, and give zero false alarms. It 
is also free.

Here's how you use it. You devise a product test, including a test 
protocol and a scoring system. I give you PAV to test. If you wind up 
saying that PAV is a good product, your test just failed the test.
