So, which versions are affected exactly?
"Latentbot won’t run in Windows Vista or Server 2008"
So presumably will also not run in Windows XP, 98, 95, 3.1 etc......
I'm guessing Server 2008 R2 might be affected as that is more Win 7 architecture than Vista architecture of "initial" Server 2008?
If the malware only runs on Win 7 & above consumer OS (& appropriate server version (see question above) for business boxen) wouldn't it just have easier to say that rather than pick 2 arbitrary unaffected OSes?
