How to remove unwanted apps that promote sonoffer.online and similar web pages

What is sonoffer[.]online?

Users do not generally visit sonoffer[.]online or similar sites intentionally - they are redirected to them via other dubious websites, deceptive advertisements, or their browsers have potentially unwanted applications (PUAs) installed on them.

Some examples of other pages similar to sonoffer[.]online are indexspotcaptcha[.]com, atinterboa[.]space and tutupdate29[.]com.

When users visit websites such as sonoffer[.]online, the web pages load dubious content or open about two or three other dubious sites. What happens next depends on the geolocations of their visitors.

These websites often trick visitors into allowing them to show notifications. More precisely, they use 'clickbait' techniques to deceive visitors into clicking the "Allow" button - sonoffer[.]online states that visitors must click the button to continue loading/browsing the page. These untrusted pages should never be allowed to show notifications because, in most cases, they contain links to other web pages of this kind, deceptive ads, etc.

sonoffer[.]online and similar sites are also promoted via PUAs.

Note that these apps can collect data relating to users' browsing habits. For example, IP addresses, entered search queries, addresses of visited websites, geolocation, etc. In some cases, they collect personal, sensitive details as well. Developers monetize the data by selling it to third parties (potentially, cyber criminals) or misuse it to generate revenue in other ways.

In such cases, users might encounter issues relating to browsing safety, online privacy, or even become victims identity theft.

Additionally, PUAs can be designed to generate advertisements. For example, coupons, banners, surveys, pop-ups, and others. These ads open dubious websites or even download and install unwanted applications by executing certain scripts.

In summary, neither websites such as sonoffer[.]online nor pages that they open are trustworthy.

Many PUAs are also rogue and do not include any useful features or improve the browsing experience. They are designed only to generate revenue for developers. Note that they are classified as potentially unwanted applications because users often download/install them inadvertently.

How did adware install on my computer?

Users sometimes inadvertently download and install unwanted apps via deceptive advertisements - they click ads that cause unwanted download/installations by executing certain scripts.

Unwanted downloads and installations also occur during download/installation of other programs. I.e., when PUAs are included into the set-ups as 'extra offers'. This PUA distribution method of PUAs is called "bundling".

Typically, offers to download and install these additional apps can be declined via "Custom", "Advanced" or other settings, or by unticking certain checkboxes within the set-ups. When users download and install programs without making these checks and changes, they often allow PUAs to infiltrate.

How to avoid installation of potentially unwanted applications?

Download software and files from official websites and via direct links. It is not safe to use torrent clients, eMule (or other Peer-to-Peer networks), third party downloaders, unofficial websites or other sources of this kind.

Avoid third party installers. Check "Advanced", "Custom" and other settings, and decline offers to download or install unwanted software. Do not click ads that are displayed on dubious websites, since they can open other untrusted websites or even cause unwanted downloads and installations.

Remove any unwanted, suspicious applications (extensions, add-ons, and plug-ins) that are installed on the browser. The same should be applied to programs of this kind that are installed on the operating system.

If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
