This Chameleon fake Antivirus is looking for the OS version (XP, Vista, Seven) and changes its name and skin: Zorton Win 7 Protection 2014, Zorton Win 8 Antivirus 2014, Zorton Vista Protection 2014, (…). It detects fake infections and displays alert messages to scare users. It belongs to the Braviax/FakeRean family.
Thanks to @kafeine for the sample
