The so-called virus is one of the thousands of browser hijacking applications that can suddenly appear on your web browser without permission. Small companies and developers often use PUPs like Flare Search, Gsearch, Mazy Search, and many others to provide questionable user experience, all while retaining profits from ad revenue.

Browser hijackers can be downloaded intentionally from official sources such as Google Web Store, although the developers mostly use software bundling and ad campaigns for such software distribution. In this way, they ensure that more people install Quick Search Tool browser extension.

Once installed, the add-on uses URL to provide seemingly relevant search results. However, users will soon notice that their browsers do not look the same anymore. All searches that they type into the search bar are redirected to, instead of, or another previously-used search engine.

This happens due to hijacker’s developer’s affiliate program with Yahoo. They do not engineer their own search engine, but rather rely on already established and trusted ones. Despite using a reputable engine, the browser extension ensures that browser redirects are initiated in a way that sponsored links and ads are visible at the top (before the genuine results by Yahoo).

Each time users click on one of such sites, they are sent to third-party websites. The developers of retain the commission from each of such clicks. While the affiliate program is nothing unique and is often used, the fact that the app is distributed via questionable sources and provides little to no benefits for the user makes the matter more concerning. hijack is a potentially unwanted application that could be distributed via software bundles and advert campaigns hijack is a potentially unwanted application that could be distributed via software bundles and advert campaigns

Browser hijackers belong to a group of computer programs called potentially unwanted applications. Besides hijackers, this category also includes adware, scareware,[2] scamware, bloatware, system optimizers, registry cleaners, and many others. That being said, this group of apps are not considered as detrimental as computer infections such as Trojans or ransomware but can cause a significant decline in user experience and sometimes compromise PC safety by reducing its security.

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 a 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. 

Nevertheless, there’s a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

While much of the data can be accidentally deleted due to various circumstances, malware is also one of the main culprits that can cause loss of pictures, documents, videos, and other important files. Potentially unwanted programs may clear files that keep the application from running smoothly.

More serious malware infections lead to significant data loss when your documents, system files, or images get locked. Ransomware is the one that is focused on such functions, so your device gets useless without access to needed data. Even though there is little to no possibility to recover after file-locking threats, some applications have features for such recovery in the system.

In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
