Avira DNS Repair Resolves Manipulations By DNSChanger
The FBI back in November managed to close down a botnet that was created with the help of a malware called DNSChanger. In operation since 2007 it grew to a size of nearly 4 million infected computer systems of which about 500,000 were located in the United States. The operators manipulated the DNS system of local computer systems to redirect users to other web pages or to replace page elements such as advertisement with their own.
The configured DNS server basically tells the web browser where to look for when a web address such as www.ghacks.net is entered into the browser's address bar. If that lookup is manipulated part or all of the page elements of the website can be replaced by the operators of the rogue DNS server.
The FBI back then replaced the DNS servers that the cyber criminals used with working servers to avoid interruption of service for users affected by the DNS server change.
These DNS servers will however be shut down on March 8th, 2012. Affected users from that day on may not be able to connect to Internet addresses anymore until they replace the DNS server with working ones.
Security company Avira, famous for their antivirus solution, has released the Avira DNS Repair-tool.
You can run the portable program on your system to see if your computer's DNS server has been manipulated by DNSChanger.
The program will reset the DNS servers to Windows default values if it finds out that they have been manipulated by the malware.
It is alternatively possible to check for manipulation manually.
Use the shortcut Windows-r to bring up the run box. Enter cmd in there and tap on the enter key to open the command prompt. Now run the command ipconfig /all and locate the DNS Servers entry. Compare what you see there with the list of rogue DNS servers below
- 64.28.176.0 - 64.28.191.255
- 67.210.0.0 - 67.210.15.255
- 85.255.112.0 - 85.255.127.255
- 77.67.83.0 - 77.67.83.255
- 93.188.160.0 - 93.188.167.255
- 213.109.64.0 - 213.109.79.255
If your DNS server IPs differ from the ones above then congratulations, you are not infected. You otherwise need to change the DNS server. While you could do that manually, you may prefer to use a program for that. You can use the Avira tool to reset the DNS Server, or a program like DNS Jumper to select a public DNS server instead.
You can download the Avira DNS Repair-Tool from the official Avira website

Does it come back after every “moment” update?
Yeah right.. Like this is going to stop defender from running =) This is comedy gold right here.
no ‘about the author’ paragraph?
For permanent disable defender is if removed complete from system no just change permission folder.
Just this is joke.
simpler, load Autoruns (SysInternals)
– filter “Defender”
– untag all entries
– reboot
nothing has changed since my 1st modification years ago
I wouldn’t disable Defender imho, it has too many hidden roots inside Windows itself. One time I tried to uninstall it using brute force scripts and then the Onedrive feature stopped working definitely. A reinstallation was needed and since those times I prefer to maintain Defender untouched. It’s a better method to install another antivirus and it will disable Defender in a safer and easier mode (e.g., Avast is the best in this way, and also Panda Cloud Free is good too).
You can not stop defender from running in background or remove it without some penalty. All you can do is to limit telemetry.
@borts,
It’s probably Smartscreen which is preventing WD from being disabled. Get rid of that and the problem should be solved: https://thegeekpage.com/disable-windows-defender-smartscreen/#How_to_disable_the_Windows_Defender_SmartScreen_via_Local_Group_Policy_Editor
Remove Windows and go for Linux.
Linux sucks dude. Besides it’s not comparable to Windows, these OSes are in different classes entirely.
I use Linux as my daily driver. It’s far more stable than Windows. When’s the last time you used Linux, 2010?
@basingstoke
You’re right, dude. Bro, linux is just a bunch of code that starts before the OS, dude. Brobrodude, that shit ain’t even got emojis, dudebrodudeman! Dudebro, it’s no way near as cool as Windows with its hardcoded abilities to make money off the user, bro. Yo brodude man, you’re the coolest dude ever man, bro. Dude.
Lol what? Windows 7 doesn’t come with any Emojis
Download Autoruns and remove the checkmark from Windows Defender. It doesn’t remove it, but it will never run. https://learn.microsoft.com/en-us/sysinternals/downloads/autoruns
Just use “Defender Control”:

Per this video,

it also works on Windows 11 too…
Win Defender, is completly the most succesful free-built in antivirus of Microsoft. Really nice product. Saved my ass a lot of times. Has updated malware database, completly strong defence
from whatever smart screen disables. Or if you want better and more upgrated (paid) program,
you can go further. But defender is always on your side.
Why would one disable Windows (or Microsoft) Defender in the first place?. I consider this to be playing with fire big time. Everybody knows that if one is using another A-V, Defender will be disabled on its own and won’t be in one’s way.
Why would I want to disable Windows Defender in the first place? It’s a great anti virus in my opinion. Been using it since Windows 8 and and never had a problem or a virus. Why mess with a good thing, if it ain’t broke don’t fix it.
How a ridiculous article!
I am thoroughly stunned.
Why Should You Disable First-Party Windows Defender?
I can only think that it is “malice or perversely intention (want you to buy a third-party AV where you can expect a back margin)” to guide invalidation without showing the premise.
No sane company will use third-party closed source programs (such as AV).
As I thought, “Ghacks Technology News” seems to be coming to downfall.
