Stop redirects to ultimate-captcha.com

What is ultimate-captcha[.]com?

If visited, ultimate-captcha[.]com loads dubious content or leads to other untrustworthy websites. Many other websites have identical behavior. Some examples are rex-news1[.]club, pushpush[.]net and nerdailingcurv[.]com. In most cases, they are opened by browsers with Potentially Unwanted Applications (PUAs) installed on them.

I.e., people do not usually visit these web pages intentionally. Furthermore, PUAs force browsers to open untrustworthy sites such as ultimate-captcha[.]com, serve advertisements and collect information relating to browsing habits of their users.

Installed PUAs open websites such as ultimate-captcha[.]com in a new browser window or tab. When opened, they redirect users to other untrustworthy websites or load dubious content. These actions depend on the geolocations of their visitors. Websites such as ultimate-captcha[.]com and sites opened through them cannot be trusted.

Opened web pages often contain deceptive ads, promote dubious software, etc. Like most pages of this kind, ultimate-captcha[.]com trick visitors into allowing it to show notifications using a 'clickbait' technique. It encourages them to click the "Allow" button so that a video can be loaded.

Even if the video starts to play, however, ultimate-captcha[.]com receives permission to show notifications. Do not give such permissions to websites of this type - if allowed, they start to display notifications that contain dubious ads, links to untrustworthy websites, and so on.

Furthermore, the aforementioned PUAs serve ads that conceal underlying content of visited websites. People who click these ads are generally redirected to various untrustworthy, possibly malicious websites. Another possible outcome is that clicked ads might execute scripts designed to download and install unwanted applications.

Furthermore, most PUAs collect data such as IP (Internet Protocol) addresses, entered search queries, geolocations, URLs of visited and other data. Sometimes they record sensitive, personal details. Developers sell the data to third parties (potentially, cyber criminals) who misuse it to generate revenue. Therefore, any installed PUAs should be removed immediately.

Typically, PUAs are advertised useful, legitimate applications, however, most force browsers to open untrustworthy websites and gather information relating to users' browsing habits. People who have apps of this type installed on their systems are exposed to risk of problems relating to online privacy, browsing safety, and so on.

Some installed PUAs might collect data that could be misused to steal users' identities.

How did adware install on my computer?

Most PUAs are downloaded and/or installed when people intentionally or accidentally click deceptive advertisements, or when developers distribute them via a deceptive marketing method called "bundling". They use bundling to trick people into downloading/installing unwanted programs through the set-ups of other software.

In most cases, information about additionally-included apps can be found in settings such as "Custom", "Advanced" and other similar parts of the set-ups. When people fail to check or change these settings, they allow additionally-included to be downloaded and installed with regular software by default.

How to avoid installation of potentially unwanted applications

Avoid downloading software from untrustworthy, unofficial websites, through tools such as torrent clients, eMule (and other Peer-to-Peer networks), and so on. The only safe way is using direct download links and official websites. Check all settings such as "Custom", "Advanced" that are included in download or installation set-ups.

Dismiss any offers to download or install unwanted apps before finishing download and/or installation. Many intrusive, deceptive ads redirect people to untrustworthy websites. Typically, these ads are displayed on dubious pages (e.g., on those relating to pornography, gambling, adult dating, and so on).

To stop browsers from causing unwanted redirects and/or showing ads, remove all unwanted plug-ins, add-ons and extensions that are installed, and apply this to software of this type 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.
