The latest WannaCry ransomware attacks all around the world reminded all of us just how vulnerable our machines really are. And while Windows Defender used to be a basic antivirus program, it has become one of the most reliable ones — even better than some of the most popular antivirus programs on the market. It currently protects more than a billion Windows users and provides protection against more than 90 billion potential threats per day.
Windows Defender’s advantageous approach
The benefits of using Windows Defender include its machine learning, cloud protection system, and behavioral analysis capabilities. Windows Defender Antivirus uses linear models for detecting malware, 97% of which are identified by the user.
Microsoft then sends all that data about suspicious signals and files to the cloud protection system, with all potential threats are determined by a mix of systems working together such as behavioral analysis, heuristic detections, and client-based machine learning models. The cloud protection system is connected to Microsoft’s Intelligent Security Graph, which collects signals from billions of sources which consist of inputs on malware and more flaws and vulnerabilities. For every malicious signal investigated, the company provides protection for more 4,500 threats and more than 12,000 users.
One of the main reasons why traditional antivirus programs usually fail is because of their non-predictive natures. They are only able to diffuse attacks similar to already existing ones or which are similar to them. Modern attackers employing the latest generation infrastructures and cloud capabilities continually generate newer threats. According to statistics, more than 86% of malware attacks are seen only on one single device and are never seen again.
