Yes, as buddy215 said, the System Volume Information Folder
is a part of System Restore
- the feature that allows you to set points in time to roll back your computer. This folder is where XP stores these System Restore points and other information such as: Distributed Link Tracking Service databases for repairing your shortcuts and linked documents; Content Indexing Service databases for fast file searches; Information used by the Volume Snapshot Service (also known as "Volume Shadow Copy") so you can back up files on a live system.
System Restore contains configuration, settings and files that are necessary for your computer to run correctly. System Restore works by taking snapshots of this vital system information and creating backups (restore points). This includes registry configuration information for application, user, and operating system settings; Windows File Protection files in the dllscache folder; COM+ Database; Windows Management Instrumentation Database; IIS Metabase configuration; Files with extensions listed in the Monitored File Extensions list and Local Profiles
. Restore points are created automatically (system checkpoints) by the operating system or manually by the user.
The System Volume Information folder is hidden/protected by default
unless you have reconfigured Windows to show it. This prevents programs from using or manipulating the files that are inside it. The files are inactive while in the data store and are not used by any utility other than System Restore.
System Restore will back up the good as well as the bad files so when malware is present on the system it gets included in any restore points. When you scan your system with anti-virus or anti-malware tools, you may receive a message that a virus was found in the System Volume Information folder (System Restore points) but the anti-virus software was unable to remove it.
