Netflowgroup[.]com pop-up ads removal instructions

What is netflowgroup[.]com?

In most cases, users end up on websites like netflowgroup[.]com after clicking some shady advertisement, through a dubious page or when some installed potentially unwanted application (PUA) opens them. In one way or another, it is not common for pages like netflowgroup[.]com to be visited on purpose. Users who have some PUAs installed on a browser or computer should remove them: it is common that such apps are designed not only to promote pages like netflowgroup[.]com but also to display advertisements, collect information.

netflowgroup[.]com pop-up redirects

When visited, netflowgroup[.]com plays a short video and shows a message encouraging visitors to click the "Allow" button to play the game (supposedly Cyberpunk 2077) for free. It uses a clickbait technique to trick visitors into agreeing to get notifications from it. Other pages suggest that visitors have to click the "Allow" button to prove that they are not robots or use another clickbait technique. Either way, netflowgroup[.]com or any other questionable page should never be allowed to show notifications. Usually, notifications from websites of this kind contain deceptive advertisements, advertise untrustworthy websites, shady software, etc. It is noteworthy that for other users netflowgroup[.]com can open a couple of other (about two, three) shady websites - it depends on their geolocation. It is important to mention that sites like netflowgroup[.]com often promote deceptive download pages for adware, browser hijackers, various scam websites, and other pages that are not trustworthy.

Users who have PUAs installed on their web browsers or computers should also know that these apps can be used as tools to gather addresses visited websites, entered search queries, geolocations, IP addresses, and even personal sensitive information. It is common that developers use gathered information for marketing purposes. Also, they sell it to third parties (potentially cyber criminals) or monetize using other methods. Therefore users may become victims of identity theft, encounter problems with web browsing safety, online privacy, etc. Additionally, PUAs can be designed to generate revenue for their developers by showing advertisements. It is common for those ads to open questionable websites or even run certain scripts to download, install unwanted apps. Some examples of ads that PUAs can generate are coupons, banners, pop-up ads, surveys.

There are many pages like netflowgroup[.]com, some examples are newsfeedzscrollz[.]com, znews-live[.]com and itabsolan[.]com. What most of them have in common is that they are used to promote shady websites, to trick users into allowing them to show notifications and they contain dubious content. If a browser has some application (or multiple applications) that promotes sites like netflowgroup[.]com (or other dubious sites, or displays ads), then it should be uninstalled as soon as possible.

How did adware install on my computer?

Quite often potentially unwanted applications are integrated in downloaders, installers of other programs as additional offers - they are bundled together with other programs. Typically, offers to download or install unwanted apps opted out/declined via "Advanced", "Custom" or other settings, or through checkboxes that those downloaders, installers have. When users finish download, installation processes without checking and changing those settings, they agree with offers to download, install bundled apps (PUAs).s Sometimes PUAs are distributed through deceptive advertisements that, if clicked, download or install those apps by executing certain scripts.

How to avoid installation of potentially unwanted applications?

Apps should be downloaded from official sites and via direct links. It is not safe to use other sources, tools for that such as unofficial pages, third-party downloaders, Peer-to-Peer networks like torrent clients, eMule, and so on. Third party installers are not trustworthy too. Also, aownloads and installations should not be finished without declining any unwanted offers. As mentioned in the previous paragraph, it can be done using "Advanced", "Custom" or other settings, or through checkboxes that can be found in downloaders, installers that have unwanted apps bundled in them. Additionally, it is advisable not to trust and click on advertisements if they appear on questionable pages. Those ads often are used to promote shady pages or even to distribute unwanted apps. Unknown, unwanted, or suspicious extensions, plug-ins, or add-ons that are installed on the web browser should be removed. The same should be applied to apps of type that are 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.
