The signs that a virus, worm, or trojan horse may be present in your system include unwanted reboots, high CPU usage, active NIC light when sitting idle, and active hard drive light when sitting idle. These signs indicate that there may be malicious activity running in the background, causing the system to behave unusually. Unwanted reboots can be a result of malware trying to gain control of the system. High CPU usage can indicate the presence of a resource-intensive malicious program. The active NIC light and active hard drive light when sitting idle suggest that data is being transmitted or accessed without user intervention, indicating potential malware activity.

It acts as a buffer zone between the internal network and the outside world, allowing controlled access to specific resources. In the context of the given options, a DMZ allows an outside network to connect to an inside network server. This means that external users or networks can access specific services or servers hosted within the organization's internal network, while still maintaining a level of security and isolation.
