How to remove apps causing redirects to ddyuei.com website?

Also Known As: ddyuei.com pop-up
Damage level: Medium

What is ddyuei[.]com?

Ddyuei[.]com is a rogue website sharing many similarities with captcharesolver.com, captchareverse.com, bruklo.com, ngthatwe.fun, and countless others. This page is designed to present visitors with questionable content and/or redirect them to unreliable and possibly malicious sites.

Users usually access such webpages unintentionally; most get redirected to them by intrusive ads or installed PUAs (Potentially Unwanted Applications). This software does not require explicit permission to infiltrate systems; hence, users may be unaware of its presence.

PUAs operate by causing redirects, delivering intrusive advertisement campaigns, and collecting browsing-related data.

ddyuei[.]com pop-up redirects

Once accessed, ddyuei[.]com checks visitors' IP (Internet Protocol) addresses to learn their geolocations. This information determines the website's further course of action.

In other words, whether visitors get redirected elsewhere and/or are presented with dubious material - depends on their geolocations. Additionally, ddyuei[.]com uses deceptive tactics to trick visitors into enabling its browser notifications.

Should the notifications be allowed, the site will begin running intrusive advertisement campaigns. The delivered ads are more than just a minor nuisance, they also endanger device/user safety.

Intrusive adverts promote (when clicked on) sale-based, rogue, deceptive/scam, compromised, and malicious websites. Furthermore, these advertisements can be triggered (by being clicked) to execute scripts designed to download/install software (e.g., PUAs) without user consent.

PUAs can have heinous functionalities, and these functions can be in varied combinations. For example, unwanted applications can force-open untrustworthy/malicious sites and/or deliver intrusive advert campaigns.

What is more, most PUAs have data tracking abilities. Information of interest includes (but is not limited to): URLs visited, webpages viewed, search queries typed, IP addresses, geolocations, and personally identifiable details.

PUA developers monetize the collected data by sharing it with and/or selling it to third-parties (potentially, cyber criminals).

In summary, the presence of unwanted software on devices - can lead to system infections, serious privacy issues, financial losses, and even identity theft. To ensure device integrity and user privacy, all suspect applications and browser extensions/plug-ins must be eliminated without delay.

PUAs usually look legitimate and innocuous. Users are enticed into download/installation and/or purchase with a broad range of functionalities. However, the features seldom work as advertised, and in most cases - they are utterly nonoperational.

Functionality and user safety are irrelevant as the only goal of unwanted apps is to generate profit for the developers. Therefore, instead of delivering on any promises, PUAs can cause redirects, run intrusive ad campaigns, and collect private data.

How did adware install on my computer?

PUAs can be downloaded/installed together with other programs. "Bundling" is the name of this deceptive marketing technique of packing regular software with unwanted or malicious additions.

Rushed download/installation processes (e.g., skipped steps and sections, used pre-set options, etc.) increase the risk of allowing bundled content into the device.

Upon being clicked, intrusive adverts can execute scripts to stealthily download/install PUAs. These applications may also have "official" promotional/download pages.

How to avoid installation of potentially unwanted applications?

It is important to research software before download/installation and/or purchase. Only official and verified download channels should be used.

Since untrustworthy sources, e.g., unofficial and free file-hosting sites, Peer-to-Peer sharing networks, and other third-party downloaders - often offer dangerous and bundled content. When downloading/installing, it is advised to read terms, explore all available options, use the "Custom/Advanced" settings, and opt-out from supplementary apps, tools, features, and other additions.

Intrusive advertisements appear ordinary and harmless; however, they redirect to highly questionable websites (e.g., gambling, adult-dating, pornography, etc.). In case of encounters with such ads and/or redirects, the system must be inspected and all suspicious applications and browser extensions/plug-ins detected - immediately removed from it.

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