Hi, Thanks for the information. Hope that Libor would come to my rescue. I think that avast has included so many sites in its hns scan and only two are said to be domains hijacked. I still expect a kind of solution to the problem.
The avast gives solution to switch to google dns to get remedy from dns hijak problem. But choosing dns as google has also posed to me a strange problem of unknown dns servers accessing my router or my network. so, i changed back to dhcp server, that is my ISP’s server resulting in poping of hns dns hijack alert after each scan.
If some domains and sub domains have the exact ip address, ( is it possible ), then the same ip of nslookup command would have shown the same addresses. I do not know more about this. I hope Libor would tell me about this. But how the addresses are shown as My Isp"s server for the foreign domains still not understood by me.
i also wish to point out that those ip servers belong to the ISP, but those were not configured dns automatically obtained in the router.
