Hi spywar,
Is this the same detection we are discussing here? → http://www.isthisfilesafe.com/sha1/4EF5762FE78DD69BC48DD8802D716937174D927C_details.aspx
& http://www.blackhatworld.com/blackhat-seo/black-hat-seo-tools/428644-get-twitter-account-checker-free-bhw.html , so this →

Could well be a PUP or else a particular packer detection:
F-PROT PecBundle
PEiD PECompact 2.xx → BitSum Technologies
See also here: http://pl.rghost.net/50771686 and (possibly your doing?) → http://www.drwebhk.com/en/virus_techinfo/Trojan.AVKill.31641.html
Also consider the low detection rate here: http://f.virscan.org/TwitterAccountChecker.exe.html
Because of the false packer detection issue my verdict is either a FP or minimal a PUP detection,
or this could be useful as an indicator for SEO SPAM detection/IDS on sites (enhancing Sucuri’s detection rate for instance).
Good job tracing it,
polonus
