What is crxbro?

crxbro is a deceptive application that claims to be the Google Chrome Internet browser. After stealth system infiltration, crxbro changes the targets of Chrome shortcuts to point to crxbro.exe. Note that the original Google Chrome browser can still be reached, however, you have to execute it directly from the installation folder. The appearance of this application is identical to Google Chrome, and yet, however, this is a fake Internet browser posing a threat to users' privacy and Internet browsing safety. crxbro tracks Internet browsing activity and generates intrusive online advertisements and is, therefore, categorized as a potentially unwanted program (PUP) and adware.

crxbro adware

Be aware that crxbro gathers various information relating to Internet browsing including IP addresses, website URLs visited, search queries, pages viewed, geo-location - these are just some examples of data types gathered by this bogus application. When you attempt to log in to websites using crxbro, an error message will be displayed and the entered login/password will be recorded. This information is stored on remote servers. In addition, it is later shared with third party companies. This behavior can lead to serious privacy issues or even identity theft. crxbro also generates various intrusive online advertisements that often conceal the underlying web content, thus, significantly diminishing the Internet browsing experience. Furthermore, these advertisements often redirect to bogus sites - clicking them is risky and may cause further computer infections. For these reasons, you should uninstall crxbro app immediately. Furthermore, if you have ever tried logging in via this browser, you should immediately change all of your passwords.

There are many deceptive Internet browsers such as crxbro. For example, TheBrowser, BrowserAir, WebVeil, Kometa, and Olcinium also claim to enhance Internet browsing by enabling a number of valuable features. In fact, these apps provide no real value for users. All adware is designed only to generate revenue for the developers. Rather than enabling the functionality promised, adware-type apps cause unwanted browser redirects and track Internet browsing activity.

How did crxbro install on my computer?

crxbro is distributed using a deceptive software marketing method called 'bundling' - stealth installation of third party software with regular software/apps. Research shows that this app often infiltrates systems during the installation of WinZipper. The developers know that many users download and install applications without paying close enough attention. For this reason, they intentionally conceal bundled software within the 'Custom/Advanced' settings. By rushing the download and installation processes, users expose their systems to various infections.

How to avoid installation of potentially unwanted applications?

There are two main steps you should take to prevent installation of adware-type programs. Firstly, closely analyze each step of the software download and installation processes. Secondly, cancel all bundled software listed for download/installation, since there is a high probability that additionally-included apps will be malicious.
