Remove software that forces browsers to open tencecatche.info

Also Known As: tencecatche.info pop-up
Type: Adware
Damage level: Medium

What is tencecatche[.]info?

People who arrive at tencecatche[.]info are presented with dubious content or redirected to other untrustworthy websites. This site operates in a similar manner to many other rogue sites including, for example, robotornotchecks[.]online, zwenews[.]biz, and vikolidoskopinsk[.]info.

In most cases, the sites are opened by potentially unwanted applications (PUAs) that are installed on browsers. Therefore, people do not generally open websites such as tencecatche[.]info intentionally. Furthermore, PUAs commonly feed users with unwanted advertisements and gather data. Note that many users download and install PUAs inadvertently.

tencecatche[.]info pop-up redirects

PUAs open sites such as tencecatche[.]info in a new browser window or tab. The site then opens two or three other dubious web pages or displays dubious content.

These actions depend on the visitor's geolocation. These web pages (including tencecatche[.]info) also demand permission to show notifications using a 'clickbait' technique: they ask for age verification to prove that the visitor is not a robot, or they use other methods to encourage the victim to click the "Allow" button.

Note, tencecatche[.]info states that clicking the button will start a download process. In fact, if clicked, it will allow it to show notifications, ads, and other (often deceptive) content. Furthermore, people who have PUAs installed on their browsers (and/or operating systems) are often served with intrusive advertisements.

For example, pop-up ads, banners, surveys, coupons, etc. If clicked, these can open untrustworthy or even malicious web pages. They might also be designed to execute scripts that cause unwanted downloads/installations. Most PUAs are used to gather details relating to users.

Typically, they target browsing-related details such as IP addresses, geolocations, URLs of visited pages, entered search queries, and so on. Some might also be used to record sensitive data. In any case, people who develop PUAs usually misuse the information to generate revenue. They often share it with third parties (potentially cyber criminals) who also misuse it.

There are many PUAs online, most of which force users to visit dubious web pages, gather user-related information, and feed them with ads.

Typically, these apps are advertised as useful, however, few PUAs operate as promised. They provide no useful functionality and cause problems relating to browsing safety, privacy, etc. People who have them installed on their systems risk becoming victims of identity theft. We strongly recommend that you uninstall these apps immediately.

How did adware install on my computer?

As mentioned, most people download and install PUAs unintentionally when they are tricked by developers who use a deceptive marketing method "bundling". They include unwanted apps in download or installation set-ups of regular software. Generally, information about the inclusion of PUAs in set-ups is hidden in "Custom", "Advanced", and other similar settings.

People allow unwanted apps to be downloaded and installed when they leave these settings unchanged. Unwanted downloads/installations can also occur by clicking dubious, deceptive advertisements. If clicked, these ads might run scripts that download and install unwanted software.

How to avoid installation of potentially unwanted applications

Download software from legitimate (official) websites and using direct download links. Do not use various Peer-to-Peer networks (torrent clients, eMule), third party downloaders, installers, unofficial websites, or other channels of this kind to download or install software.

Do not finish any installation or download without dismissing offers to download/install additional software. These options can usually be found in "Custom", "Advanced", and other similar parts of the set-ups.

Clicking intrusive ads often redirects people to untrustworthy websites or causes download/installation of PUAs, especially if the ads are displayed on web pages relating to gambling, pornography, adult dating, and so on. Typically, browsers open dubious web pages and/or display ads due to an installed PUA.

To prevent this, remove all unwanted, unknown or suspicious extensions, plug-ins, and add-ons installed on the browser and programs of this kind 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.
