A user reports recurring malware activity on a testing workstation. What should the technician have done to prevent reinfection?

Updating the local antivirus is essential for preventing reinfection of malware. Antivirus software relies on signatures and definitions to detect and remove malicious software. If the antivirus program is not updated regularly, it may not recognize new variants of malware or threats that have emerged since the last update. By ensuring that the local antivirus is up to date, the technician can provide better protection against recent malware infections and significantly reduce the risk of reinfection.

Maintaining current antivirus software also typically includes automatic updates that enhance its capabilities to detect new threats, which is crucial in a constantly evolving malware landscape. This proactive measure is foundational for safeguarding systems against known vulnerabilities and ongoing threats.
