________, also called malicious code, is software designed to gain access to targeted computer systems, steal information or disrupt computer operations.

The term you are looking for is "malware." Malware, which stands for malicious software, refers to any software specifically designed to harm, exploit, or otherwise compromise the integrity of a computer system, network, or user's data. This can include a variety of harmful programs, such as viruses, worms, trojan horses, ransomware, spyware, and adware.

Malware operates by infiltrating a system without the user's consent, often exploiting vulnerabilities in the operating system or software applications. Once installed, it can perform various functions, such as stealing sensitive information (e.g., passwords, bank details), corrupting files, or even allowing unauthorized users to gain control over the system. The consequences of malware infection can range from minor annoyances to devastating data breaches and financial losses.

To prevent malware infections, it is essential to employ good cybersecurity practices, such as keeping software updated, using strong passwords, and employing antivirus programs. Users should also be cautious of clicking on unknown links or downloading software from unverified sources.
