Making a file "undeletable" in Linux is done with attributes, specifically the "immutable" attribute. See lsattr to see attributes, chattr to change them.

However, this only answers to the proximal cause. The important thing is that your machine was put through hostile control, and the hijacker installed things for his own devious goals. In particular, he most probably installed a rootkit in order to keep the entry open despite cleansing attempts like what you are trying to do. Rootkits may have altered the kernel and/or the system binaries in ways that will not be visible from the machine itself, and which will prevent their own removal. The bottom-line is that your machine cannot be saved; there is no way you can reliably make your machine clean again, save by reformatting the disk and reinstalling from scratch.

Save yourself from future worries and headaches; nuke your system from orbit.

How do I deal with a compromised server?
This has been bothering me for a long time. I have a fairly default installation of Fedora 16 with Gnome 3. I know that since Fedora 15 (don't know about before) I have never been able to view pictures in order in shotwell.

Steps:


Open a folder with a bunch of pictures ordered by name
Double click on one of the files, it opens in shotwell
Go next, it picks a seemingly random picture instead of the next one by name


Is there any way to be able to have the next feature in Shotwell go to the next picture by name instead of a random one?

In case it matters, this happens on both my ext4 linux partition and on my NTFS windows partition.
