removal by Alice Woods - -   Also known as Dozen Search | Type: Browser hijacker

What is Can I use it? virus (also called as Dozen Search) is a browser hijacker which showed up in May 2016. The main reason why its distributors launched this questionable search engine is their expectations to earn some money. Typically, browser hijackers are set to show sponsored search results that are hidden among the normal ones. If the user is convinced to click one of such results, Dozen Search virus earns the money. With the help of such technique, the developers of this program collect thousands of dollars. That’s why they seek to increase their distribution rate and use such suspicious techniques as “bundling”. Of course, misleading advertising is also used for increasing the distribution rate of this hijacker – beware that it has been promoted as a reliable search engine that is capable of improving people’s browsing activity. However, if you have already installed this PUP on your computer, you need to remove virus without wasting your time. For that you can choose professional tools like Reimage to assist you in the process.

The main problem which is related to hijack is its redirects to sponsored websites. No matter that they seem harmless, you can always be rerouted to a malicious site that is used for promoting malware. After this intruder initiates changes on each of your web browsers (this hijacker tends to check the predetermined search engine and the homepage), it starts showing altered search results and fills them with questionable links. Unfortunately, but switching browsers does not help in this case because all browsers are affected by this PUP. Finally, we should warn you that it spreads in a bundle with cookies that are used for tracking PC users. You can lose your non-personal information while having this hijacker on your computer. Because of all these malicious activities that are typically introduced right after the program is installed, we highly recommend initiating Dozen Search removal on your computer.

The use of Dozen Search Engine

As we have already mentioned, this search provider is totally malicious and you should stay away from it. However, if you think that it is useful, there are some rules you should follow to avoid running into serious problems on your computer. First of all, you should keep away from the ads and links it might display in its search results. It is important not to click on them because you might get redirected to third-party websites, which, as practice shows, are often full of different adware, spyware and other malware waiting to infiltrate the visitors computers. Apart from the redirect issue, you should also be aware that this hijacker may spy on your browsing. It may track what websites you visit the most, what pages are your favorite, also, it keeps record of what you look for online. All this information can then be used to generate even more appealing ads for you to click on. This suggest that the longer you keep this program on your computer, the more aggressive it gets. Therefore, you should not hesitate with the removal and get rid of this virus as soon as possible.

How can you avoid this virus?

If this virus has not infected your system yet, you can consider yourself lucky. However, you should know that it does not take much for a browser hijacker to infiltrate computers. If you often download software online, you are already at risk of being infected. Especially it is true to the users, who install newly downloaded software recklessly and do not follow the installation steps thoroughly. Such behavior is very convenient to the malware creators since they can sneak this or other programs to the users computers undetected. For this reason, in the installation wizard window, you should always opt for the advanced installation settings instead of the already predetermined “Quick” or “Recommended” ones. In these settings, you will be able to see the additional software potentially added to the software package and cancel their installation. removal recommendations:
