System File Checker to check for modified Windows files. System File Checker (SFC) is a Windows utility that can be used to scan for and restore corrupt Windows system files. SFC can be used to detect and fix any modified or corrupted system files on a computer, and thus should be checked first when a user reports that their computer has been running slowly since the installation of security applications [1][2]. By checking SFC, any modified or corrupted system files can be identified and fixed, potentially improving the overall performance of the computer.

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.
