To prevent or detect malware on a computer, you can use advanced techniques such as rootkit detection tools, sandboxing, and behavior-based analysis. These methods can help identify and block malware that may go undetected by traditional antivirus software. Additionally, implementing strong access controls and user permissions, as well as regularly monitoring system logs, can help detect any suspicious activities and potential malware infections.
