TheBrowser is a Chromium-based web browser that is completely free. However, the fact that an application is free doesn't mean you should trust it blindly, especially when the app in question is a relatively unknown Web browser. TheBrowser is light and features some extra functions that some users may enjoy. However, TheBrowser also may force users to use particular homepage, new tab page, and search engines that aren't that popular. The search engine promoted via installations of TheBrowser is www-mysearch.info and people shouldn't rely on the search results it provides. Www-mysearch.info may be used to push certain Web pages to the top of the search results, so users that try to use it may be presented with unreliable results.

TheBrowser may also display unwanted advertisements during the user's browsing sessions, therefore disrupting the user's enjoyable Web browsing experience. The content of the ads displayed by TheBrowser may vary so that users may be exposed to all sorts of advertisements, including ads with harmful or suspicious content. TheBrowser may be installed alongside legitimate software as an opt-in install, so many users can avoid having to deal with TheBrowser by simply paying attention to the installation instructions when they download new software. If TheBrowser is already on your computer, you should remove it as soon as possible since it may have a disvantageous effect on your browsing experience.
