These can typically be found on Chrome Web Store, third-party websites, or installed along with freeware applications.[1]

This particular hijack is related to the Your Speed Tester extension that gets attached to Google Chrome, Mozilla Firefox, Safari, or another web browser.

These results are also often littered with sponsored links and ads, which can result in a rather frustrating browsing experience.

In fact, this is not true, as and the extension that sets it is considered to be a potentially unwanted program and a browser hijacker[2]

The hijacker promotes a site that suggests testing “your Internet speed from your new tab.” Although such a feature sounds promising, we assure you that it is not worth swapping your current homepage, new tab, and search engine address with a suspicious URL.

The search engine available on the Your Speed Tester website functions like a typical ad-supported tool that aims to generate pay-per-click revenue for its developers. As a consequence, users receive modified search results instead of organic ones, and of course, lots of these are sponsored by various third parties.

Clicking these search results could be dangerous because the developer of the search tool hardly endorses content shared on advertised websites. It simply aims to generate revenue but not to provide quality service for the users. redirect virus might unexpectedly take you to untrustworthy websites that suggest free programs, software updates, rogue system optimizers, free browser add-ons, and similar software. Please, stay away from them. If you decide to install one of them on your PC, you may unwillingly add a spyware or malware type application to your system.

VirusActivity[3] experts say that malware program distribution is on the rise nowadays, so it is necessary to keep up with the latest news about their distribution methods and functionalities. search engineThe installed extension alters homepage settings to present a questionable search engine. It tracks victim's browsing activities and fills results' pages with ads.

Search engines that deliver more ads than organic search results should not be trusted. For this reason, we suggest you remove potentially unwanted programs from your system. You can easily change your browser’s settings afterward – set a new tab page, homepage, and default search provider according to your needs.

Dissemination of browser-hijacking computer programs

Programs that hijack web browsers are known as browser hijackers, and they fall into the PUP category. Almost all programs of this kind reach victims’ computers in a very simple way – users install them without realizing it.

It usually happens when the victim doesn’t pay enough attention to statements provided in the software setup. Therefore, if you tend to install programs by clicking the “Next” button several times and then “Install” and “Finish,” – you need to use the tips we provide below.

Never install free programs from unknown web sources. Even if they seem to be useful, they may contain some dangerous components that can severely damage your computer system. Be careful when installing new programs. Developers of potentially unwanted programs know that people tend to rush when adding new software to their PCs; it allows them to take advantage of it and force unsuspecting victims to install spyware-type apps.

In general, you should always read the Privacy Policy document and also check what settings are chosen for the installation process. You must opt for Custom/Advanced mode because it is the only way to decompose the software pack. After choosing the right installation option, deselect programs that you do not need and continue.

How to prevent from getting browser hijacker

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.


Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
