As usual, not given enough time to keep up on updating servers properly (two Redhat and one NT), one of our servers has been infected by the Linux.Lion virus. I keep my personal Debian system updated by dselect all the time, but have not been able to migrate our existing Linux servers (set up before my arrival) to Debian. How can you "unprotect" the "read-only" files set up by this virus so they can be removed and/or cleaned?
