What does antivirus software do?

• A. Encrypts sensitive information
• B. Detects and removes malware from computers and networks
• C. Increases computer processing speed
• D. Facilitates online communication

Answer: (B)

Antivirus software is primarily designed to detect and remove malware from computers and networks, making it an essential tool for maintaining cybersecurity. It operates by scanning files and programs on your system to identify known malicious threats, such as viruses, worms, trojans, and spyware. When it detects any suspicious activity or files, antivirus software can either quarantine them to prevent damage or remove them entirely, thereby safeguarding your system from potential harm. In addition to real-time protection, antivirus programs often provide regular updates to enhance their ability to identify and mitigate newly emerging threats, ensuring ongoing protection against evolving malicious tactics.

The other options focus on different functions that are not the primary purpose of antivirus software. For example, while encryption is crucial for protecting sensitive information, it is not a function of antivirus software. Similarly, boosting computer processing speed or facilitating online communication involves different software tools and systems unrelated to malware detection and removal. Thus, the role of antivirus software is specifically centered around the identification and elimination of threats to maintain system integrity and security.
