Ask HN: Any Experience with VirusDie?

Hello, I am looking for a malware scanning service to offer to clients. One that has a good API so we can do the billing and is well priced. And one that is good at detecting any malware on a website. Does anyone have any experience with VirusDie? They look to be good, my only concern is that they not be good at detecting all the different kinds of malware, and i was a little concerned that they are based in Russia, as client may not like that. I am after some 1st hand experience if any has any? Or a recommendation on another provider.
