What is the function of antivirus software?

Antivirus software plays a crucial role in cybersecurity by detecting, preventing, and removing malware from computers and networks. The primary function of this software is to protect systems from malicious software, which includes viruses, worms, trojans, ransomware, and other types of harmful programs.

By scanning files and programs on a system, antivirus software identifies known malware signatures or behavior patterns that are representative of malicious activity. Upon detecting a threat, the software can take various actions such as quarantining the infected files, removing the malware, or alerting the user to potential risks. This proactive approach helps to maintain the integrity and security of user data and ensures that systems function correctly without interference from malicious entities.

Understanding the primary function of antivirus software underscores its importance in a robust cybersecurity strategy, as it is a fundamental tool in the ongoing battle against cyber threats.
