To begin with – normally, the browser redirects, or the so-called browser hijackers are not harmful. Windowsdefender.site “Virus” is a standard representative of this annoying category. As a typical page redirect, it could get integrated into all of the browsers you have installed on your computer: Chrome, Internet Explorer, Opera, Firefox, and others. All browsing programs could be targeted by such a page-redirecting software and start acting differently because of it. Some of the possible consequences include the redirection to many unknown locations changes of the appearance of your browsers regarding the default search engines and homepage/new-tab page that are set as well as some intensive ad generation.

Other browser hijacker characteristics

First of all, the known browser hijackers might indeed infect any browser. Nonetheless, the infection they could cause is not really virus-like. It could just be too irritating. In order to be seen as dangerous, an infection has to come from the activities of any form of malware – like a Trojan version, or a type of Ransomware. Exactly this type of infections are dangerous as they can lead to a variety of different problems that could be really difficult to deal with. The real malicious infections caused by Trojans and Ransomware might result in file encryption, acquisition of your online accounts credentials or other banking details, spying on you in some way, blackmailing warnings and even the possibility for identity thefts.

On the flip side, the hijackers we have stumbled across so far might just cause lots of annoyance because of their ability to send a user to pages they have never intended to visit. The changes of the usual browser homepage and/or search engine, and also the production of a huge number of ads are also possible effects of Windowsdefender.site “Virus”.

How may browser hijacker be distributed?

Most hijackers may normally find their way to your system while being put inside bundles. Really, such bundles are just many different programs put and spread around together. Users could be interested in downloading and installing such a bundle of software because they could indeed include some new games, programs or apps. Sometimes, such software bundes might also contain a piece of ad-broadcasting software like a version of adware, or a hijacker.

Also, we need to mention that there might be some more sourcse of such page-redirecting applications the likes of Windowsdefender.site. For example, torrents, spam messages, contaminated web pages, etc. Nevertheless, the number of the infections resulting from them is nothing compared to this of the contaminations coming because of the improper installation of free bundles, downloaded from the web.

Does that mean that downloading a bundle equals catching a hijacker like Windowsdefender.site “Virus”?

Don’t panic, this isn’t really the case. You may download a bundle and even try some products from it  without getting infected by any hijacker. All you must do is install the bundle in a proper way.

The correct manner of installing any kind of software involves choosing the proper installation mode. Those would be the ones letting you customize the installation process and choose what to actually install and what to leave out. The wizard choices you can always rely on are the ones which are labeled advanced or custom (or manual). Just bear in mind that selecting them is the essence of staying safe and stopping threats much more dangerous than Windowsdefender.site (like versions of Trojan and Ransomware viruses).

Why are such programs created?

The idea of advertising products, software or services isn’t a new one. At first the ads used to be broadcast on the radio or on the TV. Today, advertising is becoming more and more popular throughout the Internet. Advertisers and developers are likely to sign cooperation contracts – the first ones agree to advertise a product as effectively as possible whereas the second party agrees to pay generously for that. This business activity does not break any rules in any way – for sure, the promoting process is legal in general.
