Typically, web pages like centralheat[.]net are promoted via questionable advertisements, other untrustworthy websites, potentially unwanted applications (PUAs). In other words, it is very uncommon for pages like centralheat[.]net to be visited by users on purpose. When visited, they open a couple of other questionable sites or load their content - it depends on the visitor's geolocation. It is worthwhile to mention that PUAs can be designed to collect various data and (or) generate advertisements.

A couple example of websites that pages like centralheat[.]net can open are "Code 0x03A10 (0E10)", "You Are Our Winner Today!", download pages for potentially unwanted applications (e.g., browser hijackers, adware), and other pages designed to trick visitors into providing personal information, installing unwanted software. In some cases, a page like centralheat[.]net can open legitimate pages. However, it is strongly recommended not to trust centralheat[.]net anyway. At the time of the research, centralheat[.]net loaded a fake CAPTCHA test asking to click the "Allow" button, suggesting that this will prove that whoever has visited this page is not a robot. Other websites can use different clickbait techniques to trick visitors into allowing them to show their notifications. In one way or another, it is highly advisable not to agree to receive notifications from pages like centralheat[.]net. Usually, their notifications are used to advertise untrustworthy websites.

It is common that potentially unwanted applications are designed not only to promote questionable websites but also to serve unwanted advertisements and (or) collect various data. Usually, they generate pop-up ads, banners, various coupons, banners, etc. Their ads are used to advertise other apps of this kind, questionable websites. In some cases, ads generated by PUAs can be designed to run certain scripts and cause unwanted downloads, installations. Examples of browsing-related details that PUAs collect are geolocations, IP addresses, entered search queries, visited websites. Some PUAs can access personal data. It is important to mention that gathered information is likely to be used for marketing purposes, sold to third parties (potentially cybercriminals), or monetized in other ways. Therefore, apps of this kind can cause issues related to browsing safety, online privacy.

There are many websites like centralheat[.]net, for example, undwouldm[.]biz, thatthereis[.]biz, puiont[.]com. It is highly advisable not to trust websites of this kind (and pages that they open), or agree to receive their notifications. Additionally, it is recommended not to have any PUA installed on a web browser or computer. In most cases, users download and install apps of this kind unknowingly. Most of them are completely useless to their users and designed only to generate revenue for their developers.

How did adware install on my computer?

It is common that users download and install potentially unwanted applications unknowingly because they are distributed using questionable methods. More precisely, when PUAs are included in downloaders, installers for other programs as additional offers (when apps of this kind are bundled with other programs). Users download or install PUAs together with other programs when they finish their downloads, installations without "Advanced", "Custom", "Manual" or similar settings, or unticking certain checkboxes. In other words, when users do not decline unwanted offers/opt out bundled applications. Also, potentially unwanted apps can be distributed through deceptive advertisements. There are advertisements that can run scripts designed to download (or even install) unwanted apps. Typically, ads of this kind do not appear on legitimate pages.

How to avoid installation of potentially unwanted applications?

Downloaders and installers that have "Advanced", "Custom", "Manual", or other settings, or checkboxes are likely to have potentially unwanted applications included in them. Therefore, downloads and installations should not be finished while unwanted offers are not declined (it can be done using the aforementioned settings). Files and programs should be downloaded from official sites via direct links only. It is not recommended to trust files downloaded from unofficial pages, via third-party downloaders, Peer-to-Peer networks like torrent clients, eMule, or programs installed via third-party installers. Advertisements that questionable pages have on them should not be clicked as well - it is common for those ads to be designed to open other pages of this kind. Sometimes, those ads can execute scripts and cause unwanted downloads, installations. Unwanted, unknown, or suspicious apps (extensions, plug-ins, add-ons) installed on a browser should be uninstalled. Programs of this kind installed on the operating system should be removed too. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
