How to run an isolated application in a sandbox to protect the system from surveillance and malware?

Sandbox technology is an isolated virtual environment in which programs run with limited access rights to the operating system. All changes made by an application running in the sandbox, including writing files to disk and modifying the registry, occur within this isolated area and do not affect the main system.

Using sandboxes is extremely useful for ensuring privacy when working with suspicious files, unknown documents, or when running questionable software. If a program attempts to collect personal data from your system or install hidden surveillance modules, it will encounter isolation restrictions and will not be able to harm the main environment.

There are various tools for implementing this approach on a personal computer, ranging from built-in virtualization tools in professional versions of operating systems to specialized third-party open-source programs.

After closing the isolated environment, all temporary files and traces of activity accumulated in it can be automatically destroyed, which guarantees complete confidentiality of the working session with potentially dangerous software.
