Filecheckerapp.com Redirect
Written by Tomas Meskauskas on (updated)
What is filecheckerapp.com?
filecheckerapp.com is a fake search engine promoted using the FileCheckerApp browser extension. FileCheckerApp supposedly allows users to increase their online security using security tools designed to scan any file with 63 antivirus engines.
FileCheckerApp is a browser hijacking app that targets Google Chrome, Internet Explorer, and Mozilla Firefox. It is installed in a form of extension, add-on, or program on the Windows Operating System. As with many browser hijackers, FileCheckerApp offers a supposedly enhanced search engine and some dubious tools.
In this case, FileCheckerApp provides a scan of downloaded files and access to other security tools in one click. It also provides quick access to the latest tech and security news on over five different websites. These features may seem useful, but they are also an indication that your browser has been hijacked.
FileCheckerApp takes control over your browser, modifies settings, and replaces the homepage, search engine, and new tab URLs with filecheckerapp.com Furthermore, when you enter a search query and click the "Search" button, it redirects to filecheckerapp.com, safeserach.net, and then bing.com.
It also collects data relating to your browsing behaviour such as visited websites, IP addresses, search queries, etc. It is very likely that the collected data will be shared with third parties so that developers can generate revenue from it. Furthermore, you might receive misleading redirects to unwanted websites, or even worse, have your computer infected or experience privacy issues.
| Name | FileCheckerApp browser hijacker |
| Threat Type | Browser Hijacker, Redirect, Search Hijacker, Toolbar, Unwanted New Tab |

Like many browser hijackers and their associated fake search engines (Free Forms, ProPDFConverter, AstrologySearcher, etc.), FileCheckerApp claims to be legitimate and offers various tools, quick accesses to other websites, and so on.
In fact, regular users gain no benefit from it. Having a browser hijacker such as FileCheckerApp installed, will result in redirects to various unwanted websites that look to benefit from the dubious functionality offered.
How did FileCheckerApp install on my computer?
FileCheckerApp is available to download on filecheckerapp.com, however, if you do not recall willingly downloading it from this site, it was probably installed through ad-supportive or free software. Browser hijackers are often bundled and installed with other software.
It is possible that during the software installation process you missed a checkbox or "Advanced"/"Custom" setting in which this browser hijacker was mentioned as an extra feature or tool.
Browser hijackers are also installed through intrusive advertisements or third party software downloaders. Intrusive ads redirect to malicious websites and execute certain scripts that stealthily download or install software.
How to avoid installation of potentially unwanted applications?
Browse online with care and avoid installation of potentially unwanted programs such as as FileCheckerApp. The key to safety is caution. Install software (especially free or ad-supportive software) with care, examine each step of the installation process, check all available "Custom"/"Advanced" options, and do not miss any checkbox.
In most cases, software developers do not disclose potentially unwanted program installations properly. Do not use third party software downloaders or installers, and use only official sources and direct links. Avoid clicking intrusive ads, since they often appear legitimate, but once clicked, redirect to dubious websites.
Avoid clicking suspicious "Download" or other similar buttons on unofficial websites. If your computer is already infected with FileCheckerApp, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this browser hijacker.
