Humm, I’ve restarted my laptop and now the .fp file gets read and
the detection gets ignored.
How come I need to restart the machine? Is there any service I
could restart instead?
A restart shouldn't be necessary. Is that behavior repeatable? Are you sure you're using `clamscan` and not `clamdscan`?
I don't think clamscan uses any service, although clamdscan does. When observing `clamscan --debug ...` or `strace clamscan ...` output, I can see the ".fp" files being loaded each time clamscan is executed.
Maybe have a look at the details of what is actually being executed and the details of that execution?
Good luck!
