-== Malware prevention
-
-Malware, short for malicious software, is any software program designed to damage or execute unauthorized actions on a
-computer system. Examples of malware include viruses, worms, Trojan horses, adware, scareware, and spyware. Some
-malware, such as viruses, can severely damage a computer's hard drive by deleting files or directory information. Other
-malware, such as spyware, can obtain user data without their knowledge.
-
-Malware may be stealthy and appear as legitimate executable code, scripts, active content, and other software. It is also
-often embedded in non-malicious files, non-suspicious websites, and standard programs — sometimes making the root
-source difficult to identify. If infected and not resolved promptly, malware can cause irreparable damage to a computer
-network.

-[[machine-learning-model]]
-=== Machine learning model
-
-To determine if a file is malicious or benign, a machine learning model looks for static attributes of files (without executing
-the file) that include file structure, layout, and content. This includes information such as file header data, imports, exports,
-section names, and file size. These attributes are extracted from millions of benign and malicious file samples, which then
-are passed to a machine-learning algorithm that distinguishes a benign file from a malicious one. The machine learning
-model is updated as new data is procured and analyzed.
-

-=== Threshold
-
-A malware threshold determines the action the agent should take if malware is detected. The Elastic Agent uses a recommended threshold level that generates a balanced number of alerts with a low probability of undetected malware. This threshold also minimizes the number of false positive alerts.

-[[ransomware-prevention]]
-== Ransomware prevention
-
-Ransomware is computer malware that installs discreetly on a user's computer and encrypts data until a specified amount of money (ransom) is paid. Ransomware is usually similar to other malware in its delivery and execution, infecting systems
-through spear-phishing or drive-by downloads. If not resolved immediately, ransomware can cause irreparable damage to an entire computer network.
-
-Behavioral ransomware prevention on the Elastic Endpoint detects and stops ransomware attacks on Windows systems by analyzing data from low-level system processes, and is effective across an array of widespread ransomware families — including those targeting the system’s master boot record.
-
-For information on how to enable ransomware protection on your host, see <<ransomware-protection>>.

-NOTE: Ransomware prevention is a paid feature and is enabled by default if you have a https://www.elastic.co/pricing[Platinum or Enterprise license].
