      NEWER than swap file!

(1) Another program may be editing the same file.
    If this is the case, be careful not to end up with two
    different instances of the same file when making changes.
    Quit, or continue with caution.

(2) An edit session for this file crashed.
    If this is the case, use ":recover" or "vim -r /etc/sysconfig/iptables"
    to recover the changes (see ":help recovery").
    If you did this already, delete the swap file "/etc/sysconfig/.iptables.swp"
    to avoid this message.
"/etc/sysconfig/iptables" 579L, 54316C
Hit ENTER or type command to continue


这个是我在代开iptables时候第一屏提示的问题，请问我该怎么做，是被入侵了吗？
