How to remove DNS Unlocker virus from Chrome, Firefox and IE

DNS Unlocker app inundates one’s browser with excessive ads under the guise of providing web traffic filtering features, so get rid of this adware right away.

There is a fine line between legit and adware backed ecommerce. What is more, the average user may find it hard to tell the difference with the naked eye. It takes some system inspection and web page layout analysis to draw accurate conclusions in this regard. The criteria that matter the most are whether or not there’s a new browser add-on or plugin that’s modifying the look of visited sites, and whether identical or similar-looking ads are popping up across different domains. Speaking of DNS Unlocker program, it makes a consonant extension appear on the web service enhancements list for the browsers used on a computer, and miscellaneous items saying “Ads by DNSUnlocker” literally deluge every single page accessed via these browsers. It all appears to fit in the adware framework, and yet some further dissection of this code would make sense to better understand the essence and true motives of the application.

DNS Unlocker product isn’t in fact all about benefits

The developers of DNS Unlocker are allegedly driven by an unselfish aspiration to help some PC users access censored Internet content. The blocking that’s supposed to be addressed is customer-specific, being originally caused by the location of one’s DNS server. By simulating connection through the use of a custom server, this tool enables bypassing the filters, which basically sounds like great assistance. All of this would make a totally successful and popular startup if it weren’t for the fact that the above-listed features are just the tip of the iceberg. Here is what DNS Unlocker actually does, though: it ends up on machines in a covert way and injects ads where inappropriate.

Regular text on a website turned into ad link by DNS Unlocker

It is common knowledge that freeware cannot stay afloat unless it’s ad-supported or promotes third-party services. This trait is being heavily taken advantage of as far as adware distribution goes. DNS Unlocker does not spread by encouraging potential clients to give its remarkable functionality a shot – instead, it accompanies other free products’ installation. Some computer games, educational video creation tools and multimedia solutions go with this adware already built into their setup, therefore by agreeing to the terms of service for the former you also opt into the latter, often without even realizing it.

Ads by DNS Unlocker are generated by the aggressive browser helper object installed by the virus. It makes random chunks of text on websites appear all in capital letters and hyperlinked, with popups automatically showing up as you put your mouse pointer on those keywords. There will also be numerous banners and comparison shopping objects all over the place, regardless of the web page that’s visited. Interstitial ads won’t fail to get constantly triggered either. Stopping this frustrating commercial onslaught is manageable via ad hoc steps meant to thoroughly eliminate the potentially unwanted program.
