Link files will show the .lnk extension on Linux and it should be obvious from the icon that it's not a video file. If you have wine installed, then double clicking one will run it and malware can still cause problems when run in wine.
If your torrent client has the option to run a script or command when a download completes, you could have it delete all .lnk files in the download directory. Something like find /path/to/my/download/directory -type f -iname "*.lnk" -delete
would work.
The blue background on metal film resistors makes it really hard for me to read them. I wish they would have stuck with tan and found another way to indicate the type.
