In this day and age, you really need to have some form of defense on your system, keeping the various nasties at bay. Enter Bitdefender Total Security Multi-Device 2015, which can protect not only your Windows-based PC, but your Mac and Android-based mobile devices.
With so many new threats and hacks being detected everyday, it's incredibly important to have some kind of software installed on your system to protect you. Without it, you are really leaving yourself open to attacks and other nasties if you don't know what you are doing.
The new security software also comes with something Bitdefender calls 'BRAIN' which stands for Bitdefender Reflective Artificial Intelligence Networks. The way the BRAIN works is by "using reflective machine-learning algorithms, Bitdefender can single-handedly identify and block threats on Windows, MacOS or Android devices".
Bitdefender Antivirus elaborates, explaining its new Total Security Multi-Device 2015 software as "Bitdefender Total Security Multi-Device builds on technology awarded Best Protection and Best Performance to defend your device with just one click. It uses artificial intelligence technologies to accurately detect even the most advanced malware, such as 0-day attacks and advanced persistent threats". Considering it's protecting multiple devices in your possession, both at home and on the go, it is one of the best solutions available.
