For anyone approaching this in future we recently created CarrierWave::AttachmentScanner to easily integrate virus and malware scanning into Rails and CarrierWave.

The plugin basically hooks into file uploads using carrierwave and sends the request to a JSON/REST web service to check the files.

If the file matches a known signature then it will raise a CarrierWave:: IntegrityError.
