Opening or extracting a .rar file can sometimes trigger scripts or reveal executable files ( .exe ) that infect your system the moment you run them.

Look at where you found the link. If it came from a YouTube description, a random Discord server, or an unverified "free games" site, it is almost certainly unsafe.

Before doing anything, upload the file to VirusTotal to see if multiple antivirus engines flag it as malicious.

If you didn't purchase the game through official channels, the safest move is to delete the file and run a full system scan with Malwarebytes or Windows Defender.
