I run $ locate libns2.so Didn't output anything. $ sudo netstat -nap | grep "@/proc/udevd" Didn't output anything.
I couldn't run the first command, so I am unsure as to the filesize mentioned. However, I do have chkrootkit version 0.50 installed (default in Trisquel 8) so it might be the issue.
Still, would like to have other people's test results to compare. Thanks.
