Which term describes software or systems designed to block and remove malware?

Antivirus software is specifically designed to detect, block, and remove malware from systems. This type of software works by scanning files and applications for known malware signatures and heuristic behaviors, ensuring that infected files are isolated and eliminated, thereby maintaining the integrity of the system.

In contrast, firewall software primarily focuses on controlling incoming and outgoing network traffic based on predetermined security rules, serving as a barrier between trusted internal networks and untrusted external networks. It does not inherently remove malware but rather prevents unauthorized access and malicious traffic.

Encryption software is utilized to secure data by converting it into a code to prevent unauthorized access. While essential for data protection, it does not directly address malware threats.

Data loss prevention (DLP) software aims to guard sensitive information from being lost, misused, or accessed by unauthorized users. While it plays a critical role in data security, DLP does not function to remove or block malware.

Thus, the correct identification of antivirus software highlights its focused purpose in cybersecurity against malware.
