Returnil Virtual System (RVS) is a sandbox application for Microsoft Windows. Its goal is to prevent malware and potentially unwanted programs from permanently infecting or modifying a system.

How it works

A "session" spans from when the user activates either "System Protection" or "Session Lock" to when the user deactivates those features.

During a session, RVS virtualizes the system partition and all files, folders, partitions, and partitions/disks specified under "File Protection" by storing all writes in a cache. The cache itself can be stored on the hard drive or partially in RAM. Windows and all other programs function normally.

The user has the option of committing the changes stored in the cache to the system partition. A user can selectively commit changes in the paid-for version.^[1]

RVS offers to create a virtual partition which serves as a place to store data when under virtualization protection.

Furthermore, the RVS 2010 version includes antivirus technology with Quick, Full and real-time scanning capability. The antivirus engine is powered by F-prot.^[2]

Drawbacks

The listed limitations apply only to the current stable release, 3.0:

• Malware can still cause stability issues, until the system is restored to its original state. Malware, specifically data miners, can also steal confidential information under RVS protection.

• RVS only protects the system partition, making infection of other partitions, such as the one created by RVS, possible.^[3]

• The master boot record is locked from changes. This can conflict with certain programs.^[4]

• RVS is not yet compatible with dynamic partitioning.^[5]

Editions

The paid "RVS 2010 Home Lux" includes the basic sandboxing ability of the free "RVS 2010 Home Free", along with the ability to commit certain file or folder changes, or even an entire virtual session to the real system partition rather than discarding changes.^[6]

RVS 2010 is available in many languages, for example: English, Simplified Chinese, Japanese, Czech, German or Spanish.

System requirements

The current stable release of RVS is currently available for both 32-bit and 64-bit versions of Microsoft Windows.
