Makes you wonder if American antivirus companies are instructed not to reveal American military malware.
To guard against that you could theoretically scan using a wide range of international antivirus companies. But the problem with that is that the militaries are using the antivirus software themselves as an attack vector. Kaspersky was recently caught stealing American government secrets via its software. It's impossible to know who to trust.
Remember that most windows antivirus (except perhaps Microsoft's own) patches into the operating system somewhat similar to malware itself to do all the things it does.
Malware programs patching the same parts of the OS are likely to trip over each other.
Such a combination would be highly unstable, not to speak of incredible slow.
The amercian government secrets Kapsersky was "stealing" turned out to be US sponsored malware. Which is exactly what a good anti-virus is supposed to do. But if you want something more NSA friendly, you can always use McAffee who announced a few years ago that they will happily turn a blind eye on NSA&FBI malware.
You don't know that. Nobody knows anything because this is all spy vs spy stuff so it's impossible to know what news reports are real or propaganda or disinformation. But fwiw:
