What should you know about DNS Blocker virus

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 PC user’s browsing preferences and serve we 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. 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 themselves from clicking on these ads, no matter how catchy they look. It can be dangerous!

DNS Blocker virus delivers a lot of annoying advertisements

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 ads by DNS Blocker will lead you to corresponding web pages that provide the advertised offer. 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 a regret. If you have been browsing the websites that DNS Blocker 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 Reimage anti-spyware.

Did DNS Blocker hijack your computer? Learn how did it happen:

DNS Blocker PUP 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 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 DNS Blocker adware, take actions to fix your computer. Everything you need to do is ro remove DNS Blocker completely. If you do not know how to do it properly, you might want to follow the manual removal guide given on page 2.
