The technician should place the hard drive in an antistatic bag and secure the area containing the hard drive before leaving. This will protect the hard drive from electrostatic discharge (ESD), dust, moisture, and physical damage. Asking coworkers to make sure no one touches the hard drive is not a reliable or secure way to prevent damage. Leaving the hard drive on the table exposes it to ESD and other environmental hazards. Connecting an electrostatic discharge strap to the drive is not enough to protect it from dust, moisture, and physical damage.

 Before removing a Trojan virus from a workstation, a technician should disable System Restore. System Restore is a feature that allows users to restore their system to a previous state in case of problems or errors. However, System Restore can also restore infected files or registry entries that were removed by antivirus software or manual actions. By disabling System Restore, a technician can ensure that the Trojan virus is completely removed and does not reappear after a system restore operation. Scheduling a malware scan may help detect and remove some malware but may not be effective against all types of Trojan viruses. Educating the end user may help prevent future infections but does not address the current issue of removing the Trojan virus. Running Windows Update may help patch some security vulnerabilities but does not guarantee that the Trojan virus will be removed.

Drilling and incinerating are physical destruction methods that make the data on hard drives unrecoverable. Standard formatting, erasing and low-level formatting are logical methods that can be reversed with data recovery tools. Recycling is not a destruction method at all.

Resetting the network adapter is the best way to apply the changes made to the hosts file on a few PCs. The hosts file is a text file that maps hostnames to IP addresses and can be used to block certain domains by redirecting them to invalid or local addresses. Resetting the network adapter will clear the DNS cache and force the PC to use the new entries in the hosts file.
