Recently I have been struggling with DNS Unlocker ads which mess my web browsing up. I’ve never installed this program but it keeps coming back after a reboot even if I have removed it from Control Panel. I ran Trojan Killer and it detected a few things. After deleting the threats I’m still having the same problem. This problem causes many problems like resetting my homepage in Mozilla Firefox to about:blank and stopping me from resetting it, every so often redirecting me to other sites when I click on certain things such as a pause button for a video or some words with hyperlinks . I am running Windows 7 Norton. My IE and Firefox are affected by the program and often pop up ads by DNS Unlocker. How can I get rid of it?
What is DNS Unlocker?
DNS Unlocker is an application which claims that it enables to let you visit many blocked websites by simply connecting to their custom DNS instead of your local one. With it, you can unlock and access those websites that are blocked for political reason or other reasons freely. It sounds great, but many computer users wish to get rid of it from their computers. Why? This program indeed allows you to visit blocked sites without charge. Meanwhile, it delivers tons of advertisements to the target computers when users are surfing the Internet and viewing web pages. It usually enters the PC when you download other applications from Cnet, Softonic or other sites that have it bundled with them. This potentially unwanted program can be bundled with other freeware/shareware such as SRecorder and gets installed when you install the desired software.( As showed below)
When you download a video clip from a dubious website, the adware can also be downloaded with the video clip too. Sometimes, even simple clicking on pop-ups in unknown websites can trigger the download of adware, spyware, Trojans or other cyber threats. So watch out for those enticing images, files, pop-ups on unidentified web pages in the future. This can reduce the chances of getting invaded by adware or other unnecessary or malicious applications when you surf the Internet. If you rarely pay attention to the setup of the new program, it’s very easy for you to consent to install other additional unwanted programs. In fact, you can decline the offer of such adware by choosing the Advanced/Custom installation.
DNS Unlocker displays numerous pop-up ads on the browser/PC
Once installed, the adware allows advertisements to be played or displayed automatically. The advertisements delivered by the adware include in-text ads, pop-up ads and advertising banners. It is really annoying to view a page full of DNS Unlocker ads. For example, many specific keywords within the text of a web-page display advertising or relevant information units when you hover over the keyword carelessly. You can’t smoothly view the content in the web page due to those in-text advertisements. Please note that each time you click on an In-text ad, the websites owner gets paid by the advertiser. In addition to the in-text ads, constant coupons, offers and other pop-up ads which have text such as “Ads by DNS Unlocker”, “Powered by DNS Unlocker” or “Brought to you by DNS Unlocker” under the pop-ups also affect your browsing terribly. That’s why many can’t stand this adware and wish to get rid of it from their computers.
