What does the Virus Removal Tool focus on?

The Virus Removal Tool is specifically designed to focus on scanning for and removing viruses from a system. Its primary function is to detect malicious software that can cause harm or compromise the integrity of a computer. By identifying and eliminating viruses, the tool helps in ensuring that the system is free from threats that could lead to data loss, unauthorized access, or other negative impacts on the system's security.

While tools related to cybersecurity may address multiple threats such as spyware or performance issues, the Virus Removal Tool's core capability lies in its ability to target viruses directly. Other functionalities, such as restoring system performance or updating antivirus definitions, are typically handled by different tools or systems designed for those specific purposes, rather than the Virus Removal Tool itself. Thus, its main emphasis is unmistakably placed on the detection and removal of viruses, solidifying option C as the correct choice.
