If you must download a file from an unofficial source, follow these safety steps:

: Before opening any .rar file, scan it with updated security software or upload it to a service like Hybrid Analysis to check for hidden malware or "key generators".

: Once you extract the RAR, ensure the contents are what you expected (e.g., a .pdf or .docx ). If you see an .exe , .bat , or .msi file inside a folder where it shouldn't be, do not run it .
