biz-4u[.]com redirect removal instructions
What is biz-4u[.]com?
biz-4u[.]com functions in a similar manner to thenickelpress[.]com, behavingsoping[.]club, superinterestinginfo[.]info and many other rogue websites - redirecting visitors to other untrusted, potentially malicious web pages or displaying dubious content. Commonly, browsers open addresses such as biz-4u[.]com due to installed potentially unwanted applications (PUAs). I.e., people do not often visit these sites intentionally. PUAs are designed to open dubious web addresses, gather data, and serve advertisements.
In most cases, PUAs open addresses such as biz-4u[.]com in a new browser window or tab. When visited, these sites redirect visitors to about two or three other rogue websites or load dubious content. The way they function depends on users' geolocations. Note that biz-4u[.]com and similar pages often attempt to deceive visitors into allowing them to show notifications using 'clickbait' techniques. This particular web page suggests that a file is ready for download by clicking the "Allow" button (which actually allows biz-4u[.]com to show notifications). Typically, websites of this kind serve notifications containing website links to untrusted, potentially malicious pages, deceptive advertisements, and other dubious content. Furthermore, installed PUAs might collect browsing data and/or other information. Commonly, apps of this type target IP addresses, websites of visited pages, entered search queries, geolocations, and other browsing data. Some PUAs are capable of accessing sensitive, confidential information as well. Developers might sell the information to third parties (potentially, cyber criminals) who misuse it to generate revenue in other ways. PUAs often serve coupons, banners, surveys, pop-ups and other ads. These can open untrusted websites or even cause download/installation of unwanted applications by executing certain scripts. PUAs can be the reason behind identity theft, problems relating to browsing safety, online privacy, and other issues. Therefore, remove all PUAs from browsers and operating systems immediately.

In summary, most PUAs force users to visit dubious pages. They also display ads and collect user-system information. They deliver no real value and simply cause problems. People often download and install PUAs inadvertently.
How did adware install on my computer?
PUAs are often downloaded and installed when they are distributed by developers including them into the download/installation set-ups of other programs as 'additional offers'. This distribution method is known as "bundling". Typically, offers to download/install PUAs can be found (and declined) in "Custom"," Advanced", "Manual" and other settings. Many users fail to check and change these settings - leaving default settings unchanged, allows PUAs to infiltrate. Additionally, unintentional downloads and installations are caused through deceptive ads. When clicked, these execute scripts designed to download and install PUAs.
How to avoid installation of potentially unwanted applications
PUAs are distributed through Peer-to-Peer networks (e.g., torrent clients, eMule), unofficial websites, third party downloaders, installers and other untrusted channels, tools of this kind. Therefore, you should download only from official pages and through direct links. Check all download and installation settings such as "Custom" and "Advanced", and decline offers to download or install potentially unwanted applications. Do not click advertisements that appear on dubious web pages, since these can promote other untrusted sites or even cause unwanted download/installation of PUAs. Remove any unwanted, suspicious extensions, add-ons and plug-ins installed on the browser, and programs of this kind installed on the operating system. If your computer is already infected with rogue applications, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
