- Use an incremental backup to restore the system.
- Use a system image that was created prior to the failure to restore the system.
- Run chkdsk on the affected drive to restore system files to their post-installation state.
Explanation:
The best way to restore an operating system that has been corrupted by a virus is to use a prior system image to conduct the restore. CHKDSK is a Disk Error-Checking tool in Windows 7. It is useful in troubleshooting errors caused by corruption of the physical disk surface and can also be used to check the integrity of various files and folders within the operating system. In order to use differential and incremental backups to restore the system you would also require the last full backup as well.
