Remove Ads by DNS Unblocker

Today we have set our sights on a virus called Ads by DNS Unblocker. This bugger is a nasty piece of Adware and true to it’s nature it will create a large quantity of advertisements every time you start your browser or load a new page while working on it. These Ads could be pop-ups, banners, new pages or maybe even Ads by DNS Unblocker will turn words from any text you read into hyperlinks, accompanied with an Ad that will be shown if you hover over the word. Despite their shape these Ads do share something – they are very annoying to deal with and they will make your time browsing a living nightmare.  Before we explain what you need to do there are a couple of think you need to know beforehand.

Don’t click on the Ads

Even though the Ads may offer great discounts on things you need you should not fall for their lure. Ads by DNS Unblocker is able to read your browser’s history and past search queries and thus it will load Ads that advertise similar goods. The discounts are also part of the trap as nobody sells these things so cheap… unless he is not planning to sell anything. There is some chance for the offers to be legitimate, but we advise against trying your luck.

Further you should be careful as Ads by DNS Unblocker may try to install viruses on your computer. The Ads may even offer free downloads of software or other free stuff like wallpapers, screensavers etc. These files will almost certainly be infected with a virus. Other popular tricks including fake messages about missing plug-ins, bogus warnings about virus infestations or registry errors and more. Typically the offered software will be suggested to help with the before mentioned fake problems or presented as a stand-alone useful app like PC optimizer.

We recommend you never install what Ads by DNS Unblocker might offer you, otherwise you might regret it later. There are some very dangerous viruses propagating themselves through programs like Ads by DNS Unblocker.

Before we begin with the removal process remember that these days nearly all viruses exist under different names or under different versions using the same name. The functionality is usually retained, the difference will be in the steps that you need to perform in order to get rid of the virus. We’ve made our guide to be exhaustive for any version of Ads by DNS Unblocker, but unfortunately this also means some of these steps might be ansolutely necessary to remove whatever version of Ads by DNS Unblocker is on your computer.

Start with the guide and carefully follow the steps. If either of these do not produce the described result (you can’t find Ads by DNS Unblocker in a list for example) you shouldn’t worry and simply move on to the next step, as it appears the current one was not mandatory.


Our first step here is a reboot in Safe Mode. If you already know how to do it, just skip this and proceed to Step 2. If you do not know how to do it, continue reading:

For Windows 98, XP, Millenium and 7 Users:

Restart your computer. To be sure you don’t miss the time when you need to press it, just spam F8 as soon as the PC starts booting. In the new menu, choose Safe Mode With Networking.

Proceed to Step 2.

For W. 8 and 8.1 Users:

Click the Start button ,then Control Panel —> System and Security —> Administrative Tools —> System Configuration.Administrator permission required


Then check the Safe Boot option and click OK.  Click  Restart in the new pop-up.

Proceed to Step 2.

For Windows 10 Users:

  1. Open the Start menu.
  2. Click the power button icon in the right corner of the new Start menu to show the power options menu.
  3. Press and hold down the SHIFT key on the keyboard and click the Restart option while still holding down the SHIFT key.

Windows 10 will perform the reboot. Next do the following:

Click the Troubleshoot icon, then Advanced options —> Startup Settings. Click Restart.
After the reboot click on Enter Safe Mode With Networking (Fifth Option).

Continue with Step 2.

Even even a single copy remains after this operation all will be for nothing as Ads by DNS Unblocker will just clone itself from the copy and re-infect everything you just cleared.

While you are running these steps be aware that different messages might be created to discourage you from removing Ads by DNS Unblocker from your computer or maybe offer you to download and install something as a reward.

notepad %windir%/system32/Drivers/etc/hosts

Doing this wrong can damage your OS significantly with a big mistake. If you are not feeling comfortable, we advise you to download a professional Ads by DNS Unblocker remover. Afterwards you can use the program to scan your computer if anything remains of Ads by DNS Unblocker and also for the presence of other, more subtle viruses. Just because you can’t see them at the moment doesn’t mean there aren’t there working in the background!


Right click on each of the virus processes separately and select Open File Location. Also, End the process after you open the folder. Just to make sure we don’t delete any programs you mistakenly took for a virus, copy the folders somewhere, then delete the directories you were sent to.

Move on to STEP 6.

Type msconfig in the search field and hit enter: you will be transported to a new window. 


Go in the Startup tab and Uncheck anything that has “Unknown” as Manufacturer.

Type Regedit in the windows search field and press Enter.

Once inside, press CTRL and F together and type the virus’s Name. Right click and delete any entries you find with a similar name. If you can’t find them this way, look in these directories, and delete the registries manually:

    HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random
