Since Microsoft Windows is a popular target for a wide variety of attacks due to its widespread use, malware presents a high level of danger. Malware can have many different functions and thus offer an attacker extensive communication and control options. Among other purposes, malware may be used to obtain specific passwords, control systems remotely, disable protective software, and collect data without authorisation. The damage caused by the loss or corruption of information or applications is particularly serious for an organisation. However, the reputational and financial damage that can result from malware are often also severe.
