What action should an incident handler avoid while eradicating malware?

Enabling autorun for removable media should be avoided during the eradication of malware because it allows malicious software to automatically execute when a removable device is connected to the system. This action can lead to the reintroduction or further spread of malware, compromising the efforts to eliminate it and potentially infecting other systems. It's critical for incident handlers to take precautions that limit any automated actions that could inadvertently propagate malware, making it essential to disable such features during cleanup and recovery processes.

In contrast, utilizing antivirus scanning tools, updating security patches, and disconnecting infected systems are all best practices in handling malware incidents. These actions help to protect systems, reduce vulnerabilities, and contain the spread of malware, thereby contributing to a more effective response to the incident.
