Files ending in .rar from third-party sources can occasionally contain malware.

Use a tool like 7-Zip (Free/Open Source) or WinRAR .

Right-click the file and select "Extract Here" or "Extract to [Folder Name]" .

This means the file was "downloaded from the web" (usually a streaming service) without being re-encoded, preserving the original quality.

To view the video inside, you must first "unzip" or extract the archive.
