send samples in a password protected zip.file to virus @ avast.com
mail subject: undetected sample

You might try virustotal.com
This really isn’t suited to what the OP is considering as these have to be uploaded one file at a time. Not to mention comments from the virus labs team that this provides more trash than treasure.
