Im new to Ubuntu and im looking for some help. I've scanned my Ubuntu with rkhunter and I have some concerning results:

Warning: The following processes are using deleted files:

I would like to know if these are false positives or real threats abd how to fix them. Thank you very much!


RKHunter is famous for it's false positives. ClamAV is better!

Those 3 hidden directories are not dangerous! I get exactly these notifications since 2010.

The /etc/.java is created by Oracle Java and also by OpenJDK for digital certificates.

The /dev/.udev is created by the udevd daemon.

The /dev/.initramfs symlink for /run/initramfs is where the initial ram filesystem is mounted during the system boot process.

You can remove them without problem, they will be recreated by the system when necessary.
