In this article we are going to try and help you remove 4yendex. Our instructions cover all Windows versions as well as most browsers – Chrome, Firefox, Internet Explorer etc.
The type of software that is discussed in the paragraphs below is known as browser hijackers. The particular program of this type that might have infected your computer is 4yendex – a hijacker that is likely to change the default search engine of whatever browser you use (Chrome / Firefox), set your browser to begin redirecting you to unknown web addresses and begin generating a substantial number of online advertisements (pop-ups / tabs / boxes and others). All this happens without your informed or knowing consent. Below you will find additional important details about the infection of this kind, as well as a tested removal guide that will help you successfully uninstall the invasive program.
Are browser hijackers identified as viruses?
None of the existing browser hijackers nowadays have been classified as malicious. Malware is normally characterized by its intrusive and criminal behavior once installed on your machine, including using your banking and account credentials in order to steal something from you; locking up some important data (as a typical virus of the Ransomware family would do); or even watching you remotely via your own webcam. No such things could be performed by any browser hijacker so you are not facing a virus when we are talking about an 4yendex-provoked contamination.
Why could 4yendex be behaving in such an irritating way?
The way hijackers usually act is connected with the way they get spread on the Internet. The typical method of distributing such ad-producing programs is via bundles. A bundle is any amalgamation of diverse software versions, which usually contains a piece of ad-generating software, either a hijacker or Adware and other authentic programs like new games and interesting tools. Such mixtures are often distributed for free and any user can download them and install them because they have found such a bundle may contain really useful or fascinating products and it costs no money. And most 4yendex-caused infections in fact happen in a similar way. We have reached the point where we are going to explain why such bundles and ad-broadcasting software exist in general. First of all, most users are willing to download software for free and test it. Developers want their newly-created products popularized and tested by the public so that they put them in such combos. They also put programs like 4yendex there because they still need to gain something from such bundles apart from popularizing their own software. And by putting ad-displaying programs inside and coming up with a way to trick the users into installing the whole content of a given bundle, they become employed and paid by the marketing industry, as every single pop-up could generate big profits for the people who are interested in promoting products and services. In short, this is why such software gets created and distributed, and infects so many machines on a daily basis.
How do we install 4yendex without noticing?
To be precise, just the download of any bundle will not infect your PC with a browser hijacker or an Adware-type product. However, the improper installation manners will certainly grant you with a kind of infection. When it comes to bundles, users may easily forget that they contain more than one program and may decide to install them in the Default way, thus incorporating all the software from the bundle into their computers. Really, this is not a good idea, as such a method of installing new programs may cause even malware infections. To be safe, a user should always use the feature of the installation wizard that allows them to perform a detailed and careful installation process and to be given the opportunity to reject any programs from any bundles that are not really useful or appear suspicious. This feature is either named Advanced, or Custom.
How do we “cure” a PC contaminated with 4yendex?
