According to security researchers, FileChecker is classified as web browser hijacker. Once your web-browser has become the victim of this hijacker, it takes over your web browser like IE, MS Edge, Mozilla Firefox and Chrome. FileChecker hijacker makes changes to your internet browser’s settings, including homepage, search provider and newtab, and installs unwanted plugins deep inside your machine. This is the main reason why you need to remove FileChecker from your computer and revert back your browser search engine and homepage back to the default.
Except that the FileChecker can introduce changes to web browser’s homepage and new tab page, it also changes your search provider, which leads to the fact that use of the browser’s search becomes uncomfortable. The reason for this is that the search results will consist of a huge count of advertisements, links to undesired and ad pages and only the remaining part is search results for your query from well-known search providers such as Google or Bing.
While the FileChecker browser hijacker infection is active, you won’t be able to restore the IE, Firefox, MS Edge and Chrome’ settings like start page, new tab page and search engine by default. If you try to set your startpage to be Google, Bing or Yahoo, those settings will be automatically modified to FileChecker with the next system restart. But this does not mean that you should just ignore it or get along with this fact. Because this is not the best option, due to the FileChecker search you can have problems with the Internet Explorer, Chrome, Firefox and MS Edge, unwanted ads and even user data theft.
