Browser notification spam in general

Newads-point[.]com, altitudeedge[.]top, plestawn[.]com, and mctop[.]fun are just some of our latest articles on rogue webpages. Their goal is to trick visitors into permitting browser notification delivery; various lures can be used for this purpose (e.g., fake CAPTCHA verification, clickbait, adult-oriented content, etc.).

Spam notifications endorse deceptive and malicious content. While legitimate products or services may be encountered via these adverts – they are unlikely to be promoted in this manner by any official parties. It is most probable that this promotion is performed by scammers who abuse the endorsed content's affiliate programs to obtain illegitimate commissions.

How did contus[.]sbs gain permission to deliver spam notifications?

Websites require user consent to display browser notifications, and contus[.]sbs is no exception. Hence, you have likely accessed this page at some point and enabled the advert delivery by selecting "Allow", "Allow Notifications", or an analogous option presented on contus[.]sbs.

How to prevent deceptive sites from delivering spam notifications?

To avoid receiving undesirable browser notifications – do not enable questionable pages to deliver them (i.e., do not press "Allow", "Allow Notifications", etc.). We advise denying notification delivery from such sites (i.e., clicking "Block", "Block Notifications", etc.) or ignoring these requests in their entirety.

It is noteworthy that having adware installed on the device may result in suspicious websites being force-opened at random. Should you keep experiencing redirects of this kind, inspect the browser/system and immediately remove all dubious applications and browser extensions/plug-ins.

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