Didn't think about that part, hehe.
The first link has some information on how to prevent the installer from getting flagged though, things like "silent install" and what not.
If they do a site-case and not file-case, then it'll be tough to get them to stop flagging something from mediafire for example.
(Yet it doesn't flag from some of the other links.. so it's something related to mediafire in the end, probably, Google being more on their case, if they're used often as malware hosts)
