Everyone hasnt had this issue until recently.
Because it’s new vector for spreading malware that preys upon people running automated systems like the arr stack or just clicking stuff willy nilly.
The solution is to stop using public trackers that allow randos to upload malware.
I already made a top level reply, but I’m with the devs on this one. If you are using a tracker that allows release spam with malware, it would be counterproductive and honestly irresponsible to start playing whack a mole with it. Your software, development process and people aren’t prepared to do anti malware. Just tell your users that they’re using bad trackers and they need to switch.
Because that’s what’s happening. The arj files are malware. If someone asked me to install a water filtering system on their cars gas lines so they could use fuel from the cheap gas station I’d tell them the same thing: don’t use that gas station, they put water in the gas. Go across the street to the market rate one.
Furthermore, providing a way to filter those files just means that bad trackers that allow release spam malware will not be abandoned and the problem of that malware will get worse.
Literally get on better trackers for the sake of your own privacy, security and cpu cycles.
It sucks to say this but you need to ditch that tracker.
Those files are malware. Yes it would be great if there were some mechanism to block that specific malware (there is, use your computers anti malware) but the long term fix is to go away from where they’re distributing malware.
The whole point of distributing files like that is that people like you have automated systems that go to public trackers and grab the first thing they see that matches and extract it. .arj files can have a link in them to some payload and suddenly your wonderful home server has infected itself with malware.
Time to switch to private trackers.
Run the os off the m2. Don’t trust sd cards for anything other than bulk transient storage, simple data structures and filesystems that will be quickly moved to other systems.
