Due to the prevalence of Windows operating systems and the backwards compatibility that often exists between system generations, the threat of malware and unauthorised penetrations of corresponding IT systems is relatively high. Malware may have numerous functions and provide an attacker with extensive control options. Among other purposes, it can 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. The reputational and financial damage that can result from malware is often also severe.
