I am running an older version of freebsd FreeBSD - 6.0. Recently a new line appeared in my rc.conf file - "/root/crond". The file does not exist and I sure did not add that line to the rc.conf file. It appears to be trying to start the cron daemon. I have removed the line from rc.conf but it keeps getting put back in somehow after I reboot. I'm thinking I've been hacked but I cannot figure out how nor can I keep this line from reappearing in rc.conf.
