Explanation

SFC (System File Checker) is a built-in Windows command-line utility (run as 'sfc /scannow') that scans protected system files and replaces corrupted or missing ones with cached originals from the Windows component store. Spyware removal can sometimes delete or alter system files, making SFC the right tool to restore integrity. FIXMBR repairs the Master Boot Record, ASR (Automated System Recovery) is a full disaster-recovery process, and Repair Disk is not a specific standard tool for this purpose.
