Do not run any executable named PSX_Download_Helper_v18_Rahim_Soft.exe . Even if Windows Defender or your antivirus does not flag it immediately (malware can use "packers" to hide for 24-48 hours), the risk is unacceptable.
Third-party hosting sites frequently employ fake download buttons or intrusive pop-up advertisements designed to trick users into downloading malicious executable files instead of the actual utility.
