yes, but i wonder if you remember (or can find) how those lines got
added…that is, did you directly edit that file, or did you make the
changes in (for example) YaST or Network Manager or ??
i ask because (keep reading)

i think you have those files because of the way you added the Google
DNSs to you system–and i think you used YaST or some other tool to do
it indirectly…i say that because it seems that what you are seeing
is a series of old files saved as a result of newly created resolv.conf
that is, instead of making a new file and backing up the old one as (for
example) resolv.conf-backup01 then the next resolv.conf-backup02 and
resolv.conf-backup03 etc etc…whatever is making the new files is
adding a random suffix…
but, i do not know what is making a new file or why–what i do know is
that i directly edited my resolv.conf and removed the line in it which
had said “### Please remove (at least) this line when you modify the
file!” and i do not have random suffix old files like yours, see:
denverd@linux:~> ls -hal /etc/resolv.con*
-rw-r--r-- 1 root root 950 May 24 21:23 /etc/resolv.conf
-rw-r--r-- 1 root root 849 Sep 20 2011 /etc/resolv.conf~
-rw-r--r-- 1 root root 840 Aug 12 2011 /etc/resolv.conf.bak
-rw-r--r-- 1 root root 840 Jul 7 05:00 /etc/resolv.conf.netconfig
denverd@linux:~>
at any rate they take VERY little space and i wouldn’t delete them or
worry about them…but if you decide to do either be careful and don’t
delete resolv.conf (hmmmmm, though it might be regenerated on next
boot…i don’t know, and wouldn’t take the chance to find out)…
and, though i’m not sure why some of the icons have an X and some don’t,
i do not believe any can be removed without root powers…

what you wrote is partially true:
-there is/was(?) a windows trojan that changed which DNS servers the
infected system pointed at…
-if you had been ‘infected’ your resolv.conf would not contain the
google DNS servers…
-the google servers are NOT at risk–check your machine now at:
http://www.dns-ok.us/ (use the link at the bottom of that page to learn
more than you need to know)
-the part that is not true is “the shutting down of thousands of servers
this July 9th”: what will be shut down on 9 July are the few DNS servers
set up and operated by the FBI at the IPs which the trojan was sending
unsuspecting Windows users to…
so, when the FBI shuts down those servers (and the crooks servers can’t
be contacted) all of those folks (estimated to be 45k+ in the USA alone)
will be off the net…
