There are way too many ways to hack a website. The reality is that most WordPress security plugins can only detect malware through their signature. This means that your security scanner will only find malware if it’s popular enough to be recognizable. In simple terms: If a hacker uses unknown malware, it will potentially go unnoticed by most malware scanners. However, a security plugin like MalCare is designed to detect the slightest hint of malicious activity.  MalCare operates on an advanced learning algorithm that can detect even unknown malware. It then uses what it learns so that the same hack never works on any of the 250,000+ websites it protects.
