About a week ago I tried to make a BitChute account but it failed probably because of Firejail but anyway I had Thunderbird open and suddenly my window whent from Firefox to Thunderbird I haven't been on my computer for awhile now and I was trying to login to my Amazon account when I got an error message from Firefox so I scanned my system with RKHunter and this what it found: Code: [ Rootkit Hunter version 1.4.0 ] Checking system commands...

Please check the log file (/var/log/rkhunter.log) Should I be concerned? Running Linux Mint 17.2
I scanned with RKHunter again but this time I updated it (I thought RKHunter automatically updates itself every time you scan with it) and it found nothing, so I guessing my system must be clean.
