To start with, browser hijackers are not malicious and hazardous in the real sense of these words. Coin-Hive.com is just a standard representative of this advertising software group. As a normal hijacker, it may integrate itself in the most popular browsers you can install – from Chrome and Explorer to Opera and Firefox. Every single one of them may get affected by this program and may start acting in a different and even strange way because of the infection with a hijacker. (You can find our removal guide at the bottom of the article.) As a result, some unwanted redirections to various webpages you don’t want to load might take place. You may also face several modifications of the way your browsers look – normally, some changes of the default search engine and homepage occur. And finally, a rather intensive generation of a great number of pop-ups and other cyber ads is also possible.
What kind of an infection is the one caused by Coin-Hive.com (or any other hijacker version)?
Truly, hijackers may indeed infiltrate any computer and browser app. Nonetheless, the contamination they could cause is not generally malicious, just really annoying. Oftentimes such programs are simply too irritating and seriously get on the nerves of the affected users. On the complete contrary, infections caused by genuinely malicious programs such as Trojans or Ransomware versions are indeed more than dangerous (absolutely unlike the ones caused by a browser hijacker) and could result in file encryption, screen-locking; or other criminal activities like spying, data theft or anything illegal that could be done on the web.
If browser hijackers are not versions of malware, why are they so annoying?
The hijackers we are aware of might cause lots of annoyance since they may be able to send the victim user to web platforms that are not among the ones the user has ever intended to visit. Also, they might alter the default browser homepage and/or search engine; and provoke the production of a very big number of different online ads. This might happen as they have been programmed to perform such irritating activities in the first place because of the need of their programmers to generate higher profits. Usually, software developers earn more money if the hijackers they design are able to invoke more intensive advertising campaigns online (more redirecting, more ads, more websites/search engines and homepages promoted, etc.).
The way in which the majority of the hijacker infections occur:
Generally speaking, hijackers could be hiding inside almost everything that could be found on the Internet. Some of these programs may be included in torrents; others could come as components of web pages. Some versions may get spread via spam or online advertisements. However, the most common manner in which devices get infected by Coin-Hive.com and similar programs is when their owners download and incorrectly install any free bundle from the web. If you still don’t know anything about this term, bundles represent mixtures of lots of diverse programs, bundled and distributed together. Inside such a bundle you could find games and various apps, Adware, browser hijackers and other kinds of software. Nonetheless, keep in mind that the mere act of accessing a bundle is NEVER the real reason for any contamination. But installing such a combo in an incorrect way really is.
Performing an installation process like a PRO and thus avoiding programs such as Coin-Hive.com:
In order to complete a proper installation process, you must proceed using either the Customized or the Advanced feature that the installer displays. The other possible options such as the Quick, Default or Automatic ones are not a wise choice when it comes to your computer’s safety and health. Therefore, it is in your best interest to try to always avoid them. Only the Custom way of installing all the programs you download from the Internet is going to give you the choice to opt out of all unwanted software from any bundle.
