Virus and malware detection typically consists of software that routinely scans computers to detect known viruses, spyware, and malware, and that quarantines same. Notwithstanding the use of such software, computers can become infected in zero-day attacks (which take place before software is designed to detect the attacks), due to user error, or otherwise. A skilled outside vendor can ensure that viruses, spyware, and malware are removed from a system, and can work with an incident response team if the issue appears to have compromised company data or systems.
