This page aims to help you remove “Security error: This website requires Google chrome security plugin”. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

In the article below we will trying to summarize all the details you have to be aware of when it comes to “Security error: This website requires Google chrome security plugin”. This particular browser hijacker is generally regarded as a harmless program. Nonetheless, such software may be deeply irritating because of the typical way it changes your browsers in. These possible modifications might include the generation of some pop-up and other ads while you are browsing the web. What’s more, certain page redirects may occur rather frequently. Last but not least, your usual homepage and the search engine that you regularly use may get changed to completely new ones. Furthermore, what we can also point out about this kind of software is that it could indeed infect all of your browsers – neither Firefox, nor Chrome and Explorer can avoid such contamination.

The real nature of the programs, called ‘browser hijackers’:

Contrary to what is normally expected, “Security error: This website requires Google chrome security plugin” (or any other hijacker) is not malicious at all. However, some of the existing programs from this category could tend to exhibit some suspicious or shady traits (such as the aforementioned ones, which may indeed irritate you). But even the abilities of this software to use your last/recent browser search requests for the purpose of matching the ads flow to your supposed preferences are not enough to have this program identified as a virus. As for “Security error: This website requires Google chrome security plugin” in particular, it acts as an exemplary hijacker. Normally, it can’t do anything more harmful to your computer than the activities, mentioned above. Once more, this program is just marketing-oriented and can’t result in much trouble, simply in a lot of annoyance. Moreover, the process of creating hijackers is completely normal and legal. It is just a way to help developers generate more profit, and manufacturers – have their goods/services/products advertised.

So a virus infection cannot result from a hijacker?

To our delight, this is true. Not a single really dangerous infection could be caused by “Security error: This website requires Google chrome security plugin” or any of its siblings. This kind of software greatly differs from any form of malware. For instance, let’s have Ransomware and a Trojan virus as examples. They are really capable of harming your system – by encryption of files or data theft and more. Fortunately, nothing like that could happen as a result of a browser hijacker-inflicted infection.

Where may browser hijackers be hiding?

When we discuss the potential distribution means of hijackers, we have to say that there may be several different sources. However, some of them are more regularly contaminated by hijackers than others. Here they are:

  • Shareware/ torrents hijackers and Adware may be lurking inside (mostly illegal) torrents and shareware.
  • Any form of spam: just clicking on an advertisement, which pops up inside your browser, may lead to a hijacker infection and the generation of many more pop-ups and banners.
  • Contaminated websites: sometimes some web pages could contain ad-generating software, which you might catch via willingly, or unwillingly downloading and/or installing something from such a web address.
  • Still, the most common hijacker sources are things called bundles. These are sets of apps, programs and games, which are available for free. Sometimes such mixtures may contain ad-broadcasting programs like “Security error: This website requires Google chrome security plugin”. More precisely, you are not able to catch any hijacker simply via downloading a bundle for free. The only way to do so is to install the whole content of a bundle. Below you will learn how to prevent your system from getting contaminated by selecting the right installation feature, and installing only the programs/apps, which you need, or only the features you are interested in.

Getting software installed wisely:

It is vital to bear in mind this piece of advice. By performing the installation in this way, you will start implementing some healthy browsing /computing habits in general. The heart of the correctly performed installation process is to choose the proper installer feature. For this purpose, we will advise you to avoid the features, which install the entire bundle, such as the “Easy”, the “Default” and the “Quick” ones. Instead, get just what you really need and want via the following ones – the “Custom”, the “Advanced”, or the “Customized”.
