removal by Jake Doevan - - | Type: Browser hijacker

KwanZy.com – a bogus search tool that might flood the browser with advertisements

KwanZy.com is a dubious search engine that is presented in software bundles[1] and might enter the system silently. This program works a browser hijacker that after the installation turns browser’s address bar into a search box and replaces current search provider. Thus, after the hijack, users might find an unknown search engine once they launch their beloved web browsers. According to the Terms and Conditions, this tool may provide both sponsored and unsponsored search results. Thus, when looking for the information using KwanZy Desktop Search, you might be redirected to promotional sites and basically browse through commercial content. Undoubtedly, this activity is annoying and prevents from finding necessary information quickly. However, the research has shown that currently, this search engine is inactive. It means that no matter what search keywords you enter it will deliver you “There are no results matched your requested keywords. Please try different keywords.” message on the results page. Thus, if this useless search tool hijacked your browser’s startup page, there’s no need trying to get used to it. Just remove KwanZy.com from the Add/Remove program’s panel or speed up the process with ReimageIntego.

This potentially unwanted application (PUP) is also designed to collect particular information about the users. Once KwanZy.com is installed on the system, it starts collecting non-personally identifiable information, such as IP address, type of the browser and operating system, search queries, computer’s language, etc. All these aggregated details are necessary for providing better services, and of course, marketing reasons. In the Terms of Use, developers reveal that KwanZy might deliver advertisements because they are necessary for providing these services. Meanwhile, collected information about users allows building their profile and providing targeted ads. These ads are based on users’ interests. Thus, they are supposed to click these commercial offers more willingly. The more people click, the more advertising-based revenue developers receive. The Privacy Policy also reveals that aggregated information might be shared with Partners for the same marketing reasons. Hence, if you do not rush with KwanZy.com removal, you can expect to see an increased amount of online ads that diminishes browsing the Web significantly. What is more, they might also redirect to potentially dangerous websites where you can get infected with dangerous cyber threats.[2]

The browser hijacker spreads in software bundles

Just like many other similar applications, so-called KwanZy.com virus spreads as an optional component in freeware or shareware packages. This marketing and distribution method is called “bundling,” and widely used among developers of PUPs. When installing new programs downloaded from various online sources, users always have to choose between Quick/Recommended and Advanced/Custom installation settings. The KwanZy.com hijack might occur if users rely on Quick installation mode. Such settings do not openly disclose about third-party software and usually installs them without informing the user. As a result, people find this suspicious search engines and other applications installed on their computers and web browsers. Meanwhile, the Advanced setup allows seeing the list of “optional downloads” and rejecting their installation. During the installation, you may find the checkbox with pre-selected programs or agreements to make KwanZy Search your default search engine. Do not leave these entries ticked. Deselect them and avoid unwanted changes on your browser.

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.

 

Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data 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.
