A file is a compressed archive that bundles multiple files together. However, "SCR5.rar" is often used as a vehicle for a .scr file.

: An .scr file is technically a Windows screensaver , but structurally it is identical to an .exe executable.

: Attackers use the .scr extension because users often mistake it for a non-executable file like a video or script, making them more likely to run it.
