I stumbled across this article about IObit Cloud, an alternative to other sites like VirusTotal, talking about how it works and the guys perspective on it.
I tried it out, uploading FirefoxPortable.exe and Halo SightJacker (SightJacker.exe), which is not a virus, but Sophos has been freaking out over it lately for very suspicious behavior (it lets you spy on other players in Halo to see if they use bots).
It looks promising, but it's still a work in progress. Not surprisingly, IObit hasn't made the big news about it on it's website yet. But there's not doubt it's coming soon.
