Dezipper is a malicious application that has been developed by a well-known malware developer called Mindspark. We are of the opinion users should remove all Mindspark applications, because they are all malicious in one way or another, and Dezipper is no exception. Our research shows that the application is a potential security risk for reasons that will be discussed in greater detail. So, if you want to remove this application, please continue reading.

As mentioned, Dezipper has been developed by Mindspark Interactive Network, Inc. The company specializes in developing malicious applications, mainly bad browser toolbars, unreliable desktop utilities, and mobile apps. Mindspark is not getting the most innovative company award this year, because all of its products are basically the same. Hence, Dezipper is very similar to other Mindspark toolbars such as Webfetti Toolbar, WebmailWorld Toolbar, Audiotoaudio Toolbar, and GamingAssassin Toolbar - all of which, by the way, you should also remove. The toolbar can be downloaded from its main website at But the infection is known to be bundled with malicious software.

Dezipper is presented as an application that will better help you zip and unzip files right from your browser. It is claimed that it can also compress files for easy storage, and it supports the most popular archiving formats. However, using the compression function will require you to download an additional application. Testing has not confirmed the application's reliability when it comes to its functionality, because we are mostly concerned with its malicious actions above everything else.

Upon infection, Dezipper automatically changes the search engine and homepage to a heavily modified version of The search engine shows unreliable results, because it favors certain pages over those that are more relevant in regards to the search phrase. For all we know, it might promote an infected website that could infect your computer with Trojans, rogue applications, and other dangerous malware that will be very difficult to remove. Besides, no one wants their browsing experience to be modified for someone’s monetary gain.

All in all, Dezipper is not an application that you would want to have. Its functionality is doubtful, to put it mildly. Our researchers recommend that you remove this infection, because its search engine displays unreliable results that might favor malicious websites that can infect your computer with malicious applications, such as Trojans and so on.
