Also Known As: Ads by seumsiden.online
Damage level: Medium

What is seumsiden[.]online?

Seumsiden[.]online is designed to open untrustworthy websites and load a fake CAPTCHA test to trick visitors into allowing it to show notifications. It is noteworthy that pages like seumsiden[.]online are promoted through other pages of this kind, shady advertisements, and potentially unwanted applications (PUAs).

Seumsiden[.]online in detail

One of the main purposes of the seumsiden[.]online website is to trick visitors into clicking the "Allow" button (into agreeing to receive notifications). It displays a message claiming that visitors need to click the "Allow" button to prove that they are not robots. Other websites of this type use different clickbait techniques.

It is strongly recommended not to allow seumsiden[.]online and other similar pages to show notifications. Usually, notifications coming from pages of this type promote other untrustworthy websites. Instructions on how to disable unwanted notifications are provided below.

The second reason not to trust (visit) seumsiden[.]online is that it might open potentially malicious websites designed to trick visitors into downloading advertising-supported software, browser hijackers, and other PUAs. Also, it may open dubious pages designed to trick visitors into providing sensitive information.

Pages like seumsiden[.]online open scam websites like "Important Defender update available", "Win The New iPhone 12", "0x03A10 (0E10)", and so on. Seumsiden[.]online may open legitimate websites as well. In such case, its developers get paid a referral fee for products, services purchased on pages opened through seumsiden[.]online.

More about potentially unwanted applications operate?

Quite often, PUAs function as data collectors - they gather IP addresses, geolocations, entered search queries, visited pages, and other data of this kind. In n some cases, they collect sensitive information (for example, passwords, credit card details, names, surnames).

Another issue is that gathered information may be sold to third parties (potentially cybercriminals), used for marketing purposes, to steal personal accounts, or monetized in other ways. Furthermore, PUAs can be designed to generate advertisements.

Also, PUAs can be designed to display banners, coupons, pop-up ads, surveys. It is common for ads generated by PUAs to be used to promote questionable websites. In some cases, they are designed to download or even installation of unwanted software by running certain scripts.

Potentially unwanted applications in general

Seumsiden[.]online is similar to rcgaxg[.]com, news-ciwuwi[.]cc, allhotfeed[.]com, and many more. Most of these pages use clickbait techniques to trick their visitors into giving them permission to show notifications and promote untrustworthy pages. Also, users rarely visit them by themselves (on purpose).

How did adware install on my computer?

Pretty often, potentially unwanted applications are distributed through downloaders and installers for free programs (by bundling them together with other programs). As a rule, those downloaders have checkboxes or "Advanced", "Manual", "Custom", or other options. Those settings can be used to opt out unwanted applications.

If users do not change those settings, they agree to download or install other (bundled) applications. In some cases, users unexpectedly download or install PUAs by clicking ads designed to run certain scripts. As a rule, ads of this type do not appear on legitimate, trustworthy websites.

How to avoid installation of potentially unwanted applications?

Files and applications downloaded from unofficial websites, third-party downloaders, torrent clients, eMule (and other Peer-to-Peer networks), and similar sources should not be trusted - they might be used to distribute unwanted software. It is recommended to use official pages and direct links to download software (and files).

Downloaders and installers that have "Manual", "Custom", "Advanced", or other options, or ticked checkboxes should be checked for offers to download or install potentially unwanted applications. Unwanted applications should be deselected before completing downloads and installations.

Advertisements displayed on shady pages should not be clicked. It is possible that those ads might download or install unwanted software or open potentially malicious sites. Unwanted, suspicious apps (plug-ins, or add-ons, extensions) installed on a browser should be removed.

If there are any unwanted programs installed on the operating system, they should be uninstalled as well. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.

How to avoid browser notification spam?

Internet users should be very skeptical when being asked to allow notifications. While this is a useful feature that allows you to receive timely news from websites you like, deceptive marketers frequently abuse it.

Only allow notifications from websites that you fully trust. For added security - use an anti-malware application with a real-time web browsing monitor to block shady websites that tries to trick you into allowing spam notifications. We recommend using Combo Cleaner Antivirus for Windows.
