Vista Defender 2013 comes from the same cluster of rogues that had more than 30 different versions of active infections around 6 months ago. These included Vista Total Security, Vista Internet Security, Vista Home Security 2012 and many more. It seems like these rogues are coming back right now adorned with new titles. Vista Defender 2013 has other counterparts as well - Win 7 Defender 2013 and XP Defender 2013 have also been spotted recently.
If you get infected with this rogue, it will detect that your computer runs on Windows Vista, and the rogue's interface will changed into Vista Defender 2013. It is very easy to get fooled by Vista Defender 2013, because upon the installation it might appear just like another Windows Security Center update. However, once Vista Defender 2013 gets installed, it modifies Registry autorun settings and as a result, the rogue loads every single time you turn on your computer.
Then Vista Defender 2013 performs a fake system scan, saying that things like Devices.2000, P2P-Worm.Win32.Duload.a or Email-Worm.JS.Gigger. Then it says that all these viruses can be removed if the user registers his copy of Vista Defender 2013, and pays for the full version of the program.
