how change of dns, nullifies the vulnerability
jraju:
Hi, Scan with avast wifi inspector. If i use router dns, ie , obtain dns server address automatically, i get vulnerability of dns hijack in the router , by the scan. They give solution to change the dns in change adopter settings. I changed the dns to google and next to open dns . when i scanned the same pc again, the results show no vulnerability. How, what does that mean? The avast wifi scans the computer and connected device. My pc and other devices are shown as having no vulnerabilites.
Can you say, how , the scan results differ? Moreover, i was shown, hijacked domain as vk.com and yandex.ru, which i never visited in my life time. would expert say something on this

Hi J, first off I have been following your thread on the Avast forum. I think that you have been badly treated by some of the folks over there :shocked:
I use an old version of Avast (without the wifi scanner), but I'll try and help.
Here is a good article on DNS hijacking.

As for the entries for yandex.ru and VK.com, it may be that your ISP is using these as their default DNS servers, check the details that appear in your adapter settings with those on this page when you channge to "obtain automatically".

Those in the Avast forum are "fanboys" of Avast and may not be willing to accept that Avast maybe giving a false positive result, so try another scanner, here.

Personally I use OpenDNS.

Hi, I already checked that site. I got a different result in the morning,
Everything appears to be fine, but the check was incomplete
I raised a query to the email address of fesure, and expecting reply
What is the meaning of this status. Is my router could not be checked? or the dns server does not allow router checker to check the router? is the dns server having vulnerabilities of dns hijack. What is the fix
Now when i check the same site, i get green tick mark with the router dns settings.no issues found.
expecting reply

Hi, Samson, i noticed no change in the adapter settings , when i click yandex site. But i do know that the dns server that is in the router belongs to my Service Provider ip. But i do not know, whether this server address is used by those yandex.ru or vk.com. But funny that i could not see anything inside the router entries that would suggest the hijacking of router. If i use open dns, then avast gives no vulnerability.
Would the service provider use another service provider service for its users. strange
