good day:



when I do a rkhunter --check shows me that I have possible rootkits:



/usr/bin/rkhunter: 14795: [: /usr/lib/firefox/firefox: unexpected operator
/usr/bin/rkhunter: 14795: [: /usr/lib/firefox/firefox: unexpected operator
/usr/bin/rkhunter: 14795: [: /usr/bin/konsole: unexpected operator
Checking for suspicious (large) shared memory segments [ Warning ]


In /var/log/rkhunter.log show me this:



Warning: The following suspicious (large) shared memory segments have been found:
[21:17:06] Process: /usr/lib/firefox/firefox (deleted) PID: 9750 Owner: louie Size: 4,0MB (configured size allowed: 1,0MB)
[21:17:07] Process: /usr/lib/firefox/firefox (deleted) PID: 9750 Owner: louie Size: 4,0MB (configured size allowed: 1,0MB)
[21:17:07] Process: /usr/bin/konsole (deleted) PID: 11415 Owner: louie Size: 1,7MB (configured size allowed: 1,0MB)


With Chkrootkit only show me an infection: "tcpd" I have read in several places that it is a false positive.



Rkhunter can also be false positives? Thanks.
