False Positive for DNS changer


Recommended Posts

hi. for a while i had problems with DNS changer but i finally formatted my HDD and restarted my router and changed it's password and i no longer have any connection problems nor do i get malicious advertisments in my browser pages.


however Malwarebytes still keep detecting my registery files as DNS changers so i wanted to make sure if it is a false positive or if something was left behind (as i said i don't see any real activity regarding an actual DNS Changer malware anymore)


here is the log:

I suggest you change the DNS Settings set by your ISP to either OpenDNS or Google DNS

https://store.opendns.com/setup/#/familyshield<== opendns

https://developers.google.com/speed/public-dns/docs/using?hl=en <== Google dns


If that fixed it, I suggest to contact your ISP and make them aware of their DNS servers.

hi thanks i tried google DNS before but that didn't help however:


it seems my PC is clean now. i always clean my PC after i detect an infection (deleting cookies etc) and somehow this time it actually had an effect and worked since even Malwarebytes doesn't detect anything suspicious anymore.(scanned several times after resetting PC). maybe it has something to do with the fact that i changed my router's password and upgraded it's firmware so DNSChanger couldn't change the setting this time or something like that. i might be wrong though i am no expert. either way everything seems ok now but if it happened again i will change my DNS and will contact my ISP. thanks again miekiemoes.
