What is the role of an antivirus software in web security?

Antivirus software plays a crucial role in web security primarily by detecting and removing malware, which includes viruses, worms, trojans, and other malicious software that can harm a computer system or compromise sensitive data. By scanning files and applications for known threats, antivirus software can prevent these harmful entities from executing or spreading. It employs various detection methods, such as signature-based detection, heuristic evaluation, and behavioral analysis, to identify and address potential threats effectively.

In the context of web security, this protective function is vital, as many cyberattacks occur through infected websites or downloads. Without the intervention of antivirus software, a user’s system may become a target for cybercriminals, leading to data breaches, identity theft, or loss of valuable information. By proactively identifying and mitigating these threats, antivirus software helps maintain the integrity and security of not just the individual user’s system, but also the broader network environment.

The other options focus on aspects like network performance and user behavior, which, while important in their own right, do not align directly with the primary purpose of antivirus solutions in the realm of web security.
