How to avoid being redirected to zwenews.biz

Also Known As: zwenews.biz pop-up
Type: Adware
Damage level: Medium

What is zwenews[.]biz?

zwenews[.]biz is one of many rogue websites that redirect visitors to other dubious, potentially malicious sites or deliver deceptive content. Other examples of websites similar to zwenews[.]biz include witarheckrenning[.]pro, piedppienews[.]com, and newsapp[.]biz.

In most cases, people arrive at these sites unintentionally, since they are redirected to them by potentially unwanted apps (PUAs) installed on browsers and/or operating systems. Typically, PUAs open untrustworthy websites, display advertisements, and collect details relating to users' browsing habits.

zwenews[.]biz pop-up redirects

Websites such as zwenews[.]biz are usually opened in a new browser window or tab. They then lead to other dubious websites (about two or three ) or display dubious content. These actions depend on visitors' geolocations. Web pages opened through zwenews[.]biz could be malicious and used to promote malicious or other unwanted software.

Furthermore, zwenews[.]biz asks visitors to prove that they are not robots by clicking the "Allow" button. This is a 'clickbait' technique used to trick people into allowing sites such as zwenews[.]biz to show notifications, ads, and other unwanted content. Do not give dubious sites these permissions.

Installed PUAs are often designed to operate as information tracking tools. They gather details relating to users' browsing habits (IP addresses, entered search queries, URLs of visited pages, geolocations, and so on). In some cases, PUAs are used to record private/sensitive information.

Developers usually share the details with other parties who misuse them to generate revenue. Some of these third parties might include cyber criminals. These apps commonly serve annoying, intrusive advertisements such as coupons, banners, surveys, pop-up ads, and so on.

People who click them are usually redirected to untrustworthy (potentially, malicious) websites, however, some of these ads might run scripts that download and install unwanted apps. To avoid issues relating to online privacy, browsing safety, or even identity theft, uninstall all unknown, unwanted applications immediately.

Developers promote PUAs by offering useful features, however, they do so only to trick people into downloading and installing the apps. Once installed, most PUAs perform actions that help developers to generate revenue, and they do not operate as advertised. Most are useless and often lead to various problems.

How did adware install on my computer?

In most cases, unwanted apps are downloaded and/or installed together with other software that people download from the internet intentionally. This is when developers distribute PUAs using a deceptive marketing method called "bundling". They trick people into unwanted downloads/installations by including PUAs into the set-ups of other programs.

Typically, offers to download or install additional software are hidden in "Custom", "Advanced", and other settings. When people download and install regular software (often freeware) without changing these setting, they allow PUAs to be downloaded or installed through the setup of the program.

Unwanted downloads and installations are also caused through intrusive advertisements. If clicked, many execute specific scripts that download/install unwanted software.

How to avoid installation of potentially unwanted applications

Software should be downloaded from official web pages and using direct download links. Do not use other tools or sources such as Peer-to-Peer networks (torrent clients, eMule), unofficial websites, third party downloaders, installers, or other similar download/installation channels.

Check "Advanced" and "Custom" settings of download/installation setups and dismiss offers to download/install any unwanted software. Do not trust intrusive ads, especially if displayed on dubious websites - they often cause redirects to other potentially malicious web pages or unwanted downloads and installations.

Remove all unwanted or suspicious apps (add-ons, plug-ins, extensions) installed on the browser and programs installed on the operating system immediately. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
