Remove DNS Blocker virus (Removal Guide) - 2021 update

removal by Jake Doevan - - | Type: Adware

DNS Blocker virus is an adware that can affect your web browser and show advertisements

DNS Blocker is a potentially unwanted program (PUP). There are many versions of this adware-type program, such as DNS Unlocker, DNSBlock, DNS Keeper (click on links to read more about these programs). However, all of them function the same way – they collect certain information about the PC user’s browsing preferences and serve advertisements during browsing sessions.

DNS Blocker can affect all web browsers, including Chrome, Firefox, IE, or Edge. Once installed, it will start to inject advertisements into websites user visits, such as banners, in-text links, and open ads in new browser tabs or windows.

Questions about DNS Blocker virus

Ads by DNS Blocker look useful at the first glance because they usually present various offers that supposedly should help to save time and money when shopping online. However, we advise PC users to refrain from clicking on these ads, no matter how catchy they look.

It is not wise to click on them because these ads can be dangerous.

Unfortunately, we have to disappoint you by saying that DNS Blocker ads are not meant to be useful for you. They are designed to promote particular third-party web pages and boost their web traffic. Therefore, you should not expect that clicking on these ads will lead you to corresponding web pages that provide the advertised offer.

DNS BlockerDNS Blocker is yet another adware that shows sponsored ads and can redirect users to dubious websites.

Most likely you will be redirected to questionable third-party websites; unreliable Internet sites usually offer questionable downloads or ask the user to provide personal information. Take into account that some websites you might be redirected to can be malicious. Therefore, we recommend you to remove DNS Blocker adware from your computer without regret.

If you have been browsing the websites that adware ads have addressed you to, we strongly advise you to scan your computer with a good anti-spyware program that would be powerful enough to detect the latest computer threats and ensure the best computer protection. For that, we recommend opting for SpyHunter 5Combo Cleaner or Malwarebytes antivirus programs.

If you want to remove DNS Blocker virus manually, you will find instructions at the bottom of this article. Keep in mind that manual removal can be tricky so we recommend using a security program instead.

Potentially unwanted programs spread via the bundling method

Adware and other PUPs spreads via modified software installers, which provide “recommended downloads.” You can encounter such installers if you tend to download suspicious software from even more suspicious download websites. Be aware of the fact that many free programs that you can access and download for free offer installing additional software alongside them. Such additions often prove to be potentially unwanted programs.

If you do not want to install these additional components, you must select the Custom or Advanced installation option and reject all of them. Please take note that Standard, Default, or Basic installation settings are not worth your trust since they include pre-selected agreements to download and install optional components alongside the main software.

If you believe that your computer was infected with adware, take action to fix your computer. Everything you need to do is to remove adware completely. If you do not know how to do it properly, you might want to follow the manual removal guide given below

DNS Blocker removal instructions

If you want to remove DNS Blocker virus, firstly, you have to choose how you want to do it. You can uninstall it automatically using one of our recommended programs and at the same time protect your computer from future spyware and malware attacks, or, you can do it manually.

We must warn you that if you opt for the manual removal method, you have to be very careful.

After uninstalling this potentially unwanted program (PUP) and fixing each of your web browsers, we recommend you to scan your PC system with a reputable anti-spyware. This will help you to get rid of DNS Blocker registry traces and will also identify related parasites or possible malware infections on your computer. For that you can use our top-rated malware remover: ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes.

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.


Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
