But the best thing about it is that it has proven to be especially powerful against ransomware.
With Behavior Shield we can protect against zero-second threats, malicious programs and cyber spying on passwords and bank account details that would normally not be possible using traditional detection methods. And finally, there’s the powerful Avast cloud that puts all the actions in a global context and allows for ultra-fast reactions across all the protected endpoints. On top of that, there is a lot of logic that allows us to distinguish good from bad – and for that, we rely on artifical intelligence, namely neural networks. At the heart of it is a real-time graph that describes all the actions that the individual processes in the operating system are doing, including their relations, code injections, etc. This may sound relatively easy to do, but in fact, Behavior Shield is very complex under the hood. So, if for example, your mail client starts a javascript interpreter connecting to the internet, Behavior Shield will step in, as this isn’t normal behavior for a mail client and could lead to a malicious download. Once it identifies something really fishy, it stops the action and reports the behavior to you, before any damage can be done. It carefully observes program behavior and if it notices something uncharacteristic, it starts looking even closer.
As real-life security would observe a crowd for suspicious or dangerous behavior, Behavior Shield monitors all the programs running on your PC that have passed through initial security checks. An additional layer we added to Avast 2017 is a patent-pending technology that we call Behavior Shield.īehavior Shield can be compared to real-life security that is on patrol duty at a major event. Our engines are protection layers, that can step in at different stages to safeguard you from threats. We recently released a new version of our flagship PC product, Avast 2017, which uses various engines, including CyberCapture, to scan for threats. Behavior Shield comes standard in all versions of Avast 2017, protecting you from zero-second threats, ransomware and other malicious programs
