Will System Recovery Eliminate a Trojan Virus?
If you are a backup person, you are probably confident that you can always restore to existing backups that are located in external or networked drives, CDs or DVDs, or online backup storage like Mozy Backup. However, if you don't backup your system and files, the only option is by using system recovery options - System Restore or recovery console.
System Restore is the easiest way to eliminate the existing system that is currently infected. By simply choosing a restore point that does not contain any virus or malware infection, you will be able to use Windows again without the need to re-format or reinstall a fresh copy of Windows. The only disadvantage to using System Restore is that you have to reinstall the programs and updates that the restore point or snapshot doesn't contain.
So yes, using system recovery tools such as having a complete system backup, system restore points, and access to recovery console will help eliminate infections.
Note: Recovery tools should be used if an antivirus or anti-malware software could not remove malware in Windows, or if you would rather roll back to previous system state or system backup.
