TheBrowser – How Did It Hijack my PC
TheBrowser may use the bundling downloads – a very common strategy for most third-party websites out there. It is a useful marketing tool push the installation of third-party applications in the setup programs of other legitimate software the user downloads from the web ‘as a free extra’ to it. Bundling is commonly met in most third-party direct software download sites, however it can also be seen when you download software via torrent sites. This is why experts warn users to stay away from such when it comes to programs and to always look for the official provider’s website, because they might just miss such installation step during the setup – it happens even to experienced users.
TheBrowser – What Does It Do?
Once installed on your computer this particular Chromium-based application may perform various activities on the user PC. One of those activities may be running processes in the background such as its built-in extensions even after the program has been ‘X’-ed. What is more, the program may create and modify the Windows Registry Editor with values that may set its executable or extensions to run every time on system start-up or even in specific times. The program may also set itself as the default browser opening itself every time the user clicks on a web link.
What is more, the software may situate various types of cookies in the user PC that may track user information such as:
- Online searches.
- Online clicks.
- Browsing history.
- User information.
- Credentials
This information may then be used in several different ways by third-parties and the company of-course does not take any responsibilities to what third-parties do with the user information and this is why it is regarded as unsafe.
Third-party advertisements may conceal many different danger for the user:
- Collect his personal details via fake surveys and sell his information to malware writers who develop tailor-made malware based on that very computer or other interested parties.
- Scam the user out of his information or money using social engineering and a fake tech support site as a front to gain access to the user PC.
- Infect the user PC with scripts that cause redirects to malicious link, executing malware onto the user PC.
- Scam the user via fake prize claims, product trials of freeware and others.
This are the main reasons why TheBrowser is considered to be indirectly unsafe towards users and this is why experts recommend taking actions against this third-party ad-supported PUP (Potentially Unwanted Program).
