Sorry, can not reproduce with any version of SuperSU. On all Samsung devices we have (Note II incl.) the scanner is not showing any problem. In such a case, it could be caused some rooting methods, which, in some cases, are done with suspicious exploits, but anyway, until the APK does not contain malware it should not be detected. Officially we do not support custom ROMs and rooted devices, which is hardly good response to false detection though; we deployed a new clean set with SuperSU versions and will try to avoid next issues like this, sorry for that. I checked our release versions of VPS - there is an old detection as a PUP for old superuser application beeing installed on newer devices (where SuperSU should be instead), but nothing more. Thanks for understanding.
