### REPLY:
The best way to prevent malware from infecting a computer system is by implementing strong security measures such as using firewalls, intrusion detection systems, and encryption. Additionally, regularly performing backups of important data and storing them offline can help recover from a malware attack. It is also recommended to disable or restrict unnecessary services and ports, and to regularly monitor network traffic for any suspicious activity.
