Free Linux-based rescue environment to scan and repair a Windows PC that will not boot.
Avira Rescue System is a free bootable antivirus built on Linux.
It starts the computer from a USB stick or DVD, so malware inside Windows never gets a chance to run or hide.
Besides the virus scanner it includes a file manager and a web browser, which help you copy files to safety and look up fixes while Windows is down.
The same detection technology as Avira Free Antivirus, updated before each scan.
Runs independently of Windows, so locked and hidden malware files are accessible.
Copy documents and photos to an external drive before repairing the system.
Look up instructions or download tools while the PC is in rescue mode.

If the cause is malware, often yes. If Windows itself is damaged, use the Windows recovery tools after cleaning.
It contains a complete Linux system plus the antivirus engine and its signature database.
