What is witarheckrenning[.]pro?
Once opened, witarheckrenning[.]pro redirects people to other rogue websites or displays dubious content. In any case, avoid this website and do not trust it. There are many websites of this type online including, for example, mirox22[.]biz, push-tools-system[.]com, and gunnepaa[.]xyz.
Browsers generally open these web addresses due to potentially unwanted applications (PUAs) installed on them. People do not often visit websites such as witarheckrenning[.]pro, or download/install PUAs, intentionally. Furthermore, PUAs feed users with ads and record private information.
witarheckrenning[.]pro is commonly opened by installed PUAs in new browser windows or tabs. The site then opens two or three other untrustworthy websites. Alternatively, it might display deceptive, untrustworthy content. These actions depend on visitors' geolocations.
Note that witarheckrenning[.]pro often tricks people into allowing it to show notifications by encouraging them to click "Allow" so that they can supposedly stream a video. Typically, these sites use various 'clickbait' techniques. People who allow sites such as witarheckrenning[.]pro to show notifications are served with ads and/or various irrelevant notifications.
Furthermore, most PUAs record browsing-related data such as IP addresses, URLs of visited websites, geolocations, entered search queries, etc. Developers then share the details with third parties (potentially cyber criminals) who misuse them to generate revenue.
These actions can lead to problems with privacy, browsing safety, and even cause identity theft. PUAs can also deliver intrusive ads (coupons, banners, pop-ups, surveys, and so on).
These conceal underlying content of visited websites and, if clicked, redirect to untrustworthy websites or even execute scripts designed to download/install other unwanted apps. Therefore, you should remove these applications immediately.

PUA developers advertise their software by offering useful tools, features, etc., however, these apps are useless and designed only to generate revenue for themselves and other parties. Having PUAs installed risks many problems and so you should remove them immediately.
How did adware install on my computer?
In most cases, download/installation of PUAs is caused when people click intrusive (deceptive) ads or when developers use a deceptive marketing method called "bundling". They use this method to trick people into downloading and/or installing potentially unwanted apps together with other software that people wish to download and install intentionally.
They achieve this when people fail to check settings available in the set-ups. Offers to download or install unwanted apps can be found in "Custom", "Advanced", "Manual" and other similar settings. People who leave these unchanged usually allow PUAs to be downloaded and installed with regular software.
How to avoid installation of potentially unwanted applications
The safest way to download software is using official websites and direct links. Other channels or tools such as torrent clients, eMule (and other Peer-to-Peer networks), third party downloaders, installers, unofficial websites, etc., should not be used. These tools are often monetized by promoting unwanted programs.
Do not finish any download or installation without checking "Custom", "Advanced", and other settings that are included in the setup. Unwanted downloads or installations can be avoided by dismissing additional offers in the set-ups.
Avoid clicking intrusive ads, especially when they are displayed on web pages relating to gambling, adult dating, pornography, and other dubious sites. If you believe PUAs or suspicious apps (extensions, add-ons, plug-ins) are installed on the browser, remove them immediately.
The same should be applied to 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.
