freitasm: Sorry, but those DNS are wrong for Vodafone TelstraClear network, and I don't think malware has anything to do with this specific case.
i did some testing with tcl cable recently, after it was going really slow, and vodafone's dns servers seemed to work better than the tcl ones. they both had better google destinations, and higher hit rate / better average dns load time. (tcl was slightly faster some of the time, but much lower hit rate)
only problem was they were in auckland, whereas tcl were anycast.
google seemed to route via au/us for tcl. it shows a sydney hop, but latency over 200 msec, suggesting reverse path via the US.
