There are some torrrents showing up with .lnkextension (ex: movie.mp3.lnk, tvshow.mkv.lnk...) and automated software (Sonarr, Radarr, Lidarr, qBittorrent RSS Downloader) could pick those torrents (but not import).

These (fake) torrents include a .lnk file that executes a script on your Windows

HOW TO exclude from download on qBittorrent.

• Go to Options -> Downloads

• Enable "Exclude file names"

• Add patterns:

(one by line)

*.mp4.lnk  
*.mp3.lnk  
*.mkv.lnk
*.torrent.lnk 

Or exclude all together: *.lnk
