removal by Jake Doevan - - | Type: Browser Plugins
12 is a browser hijacker that has been released quite a while ago. It is a suspicious program that you should protect your computer from before it enters your computer system unnoticed. It is described as a potentially unwanted program (PUP), so it goes without saying that you should not trust this program.

Should you remove virus from your computer?

In fact, you should, and the sooner, the better. This PUP is definitely not a trustworthy program. First of all, we would like to state a fact that this application can be installed completely without your knowledge. However, it happens because the majority of computer users act careless and rush when installing new programs on their computers. However, later on, we will explain how to avoid placing malware on your computer without an intention to do that. Now, let’s talk what does this program do once it is inside your computer and active. browser redirect virus

When hijacker slithers into a computer system, it finds Internet browsers that you use and adjusts settings of them. To be precise, it changes homepage address on all of them to, plus, it sets this search-providing website as your default web search provider. At the first glance, this web page looks like an entirely normal search engine, but you will notice how oddly it works once you start to use it. You shall notice that redirects you to suspicious third-party web sources once you click on search outcomes that it generates. We can explain why these redirects occur – it is believed that browser redirect virus gets pay-per-click profit by promoting third-party websites and driving web traffic to them. Unfortunately, some of the third-party sites can be insecure, and some of them might even try to persuade you to install bogus software updates that spread malware alongside them. On the whole, you should avoid installing ANY kind of apps, or files from untrustworthy web sources, especially ones that you enter in an involuntary manner. If you do not wish to experience such redirects, we strongly recommend you to uninstall virus using a powerful anti-spyware tool, for instance, Reimage. Such software can scan your PC, detect and eliminate dangerous computer parasites and threats from it for good.

How can hijack my computer?

It is hardly possible to download this rogue application by your choice. That is because this deceptive program always spreads bundled with free programs and due to this fact it has been categorized as a potentially unwanted software. To avoid downloading browser hijackers, adware and other potentially unwanted programs that are frequently attached to various free programs and sometimes are barely noticeable, you should be more attentive while installing new software on your system. Additional programs cannot be noticed before you launch an installer of the program that you plan to install. Instead of choosing Default or Standard installation method, opt for Custom or Advanced one. Then, you may notice suggestions to change your homepage, default search engine or to install various plug-ins, toolbars, add-ons or extensions. You should refuse to install such additions. Otherwise, you will agree to install PUP or other similar programs and later experience redirects, system slow downs, pop-up ads and other inconveniences during your browsing sessions. If you are already experiencing these issues, follow the removal guidelines that are provided on page 2.

How to remove virus?

We recommend using a reliable anti-spyware to remove this rogue program as this way all potentially unwanted applications and files related to them will be eliminated. Of course, you can try to delete this browser parasite manually, but make sure you do it carefully and thoroughly.
