What is a common effect of malware on an organization's systems?

Loss of data integrity is a common effect of malware on an organization's systems because malware can manipulate, corrupt, or completely destroy data within the system. When malware infiltrates a system, it often alters data in ways that can go undetected for long periods. This alteration can occur through various means, such as encrypting files for ransom or modifying databases to inject false information. Consequently, the trustworthiness of data is compromised, leading to potentially severe consequences for the organization, including misinformation, operational disruptions, and legal challenges.

In contrast, the other options suggest improvements or benefits, which are not accurate representations of malware's impact. Malware typically degrades system performance, undermines data security, and detracts from the user experience, making loss of data integrity the most direct and relevant consequence.
