How can malware be prevented or detected on a computer system?

### REPLY:
One way to prevent and detect malware on a computer system is by using advanced threat detection software that employs machine learning algorithms to analyze network traffic and identify potential malicious activity. Additionally, implementing a robust security infrastructure with intrusion detection and prevention systems can help detect and block malware at the network level. Regularly conducting vulnerability assessments and penetration testing can also help identify and patch potential security weaknesses before they can be exploited by malware.
