Compressed archives like .rar files are often used to hide malicious payloads from initial antivirus scans.

: Using outdated extraction software can expose your system to exploits where merely opening a crafted archive could automatically run malicious code. Fake WinRAR downloads hide malware behind a real installer

: Malware creators may use unusual file names or "double extensions" within the archive to trick users into running a virus thinking it is a legitimate game component.

: These archives can contain executable files ( .exe , .bat , .msi ) or scripts that, when run, can install ransomware, steal personal data, or create a backdoor for remote access.
