What is FileOpener?

As the title of the program indicates, FileOpener is an application designed for opening various formats of files. The app is supposed to enable users to view and edit documents and file formats, such as doc, dot, xls, ppt, etc., support audio and video formats, allow users to copy document info and so on. Sounds great, isn’t it? The app seems really useful and it’s possible that it is. Nevertheless, you should be aware that this application belongs to ‘adware’ and ‘PUP’ categories. If you would investigate the official website of this program, you would notice a statement that FileOpener is “Tested as being completely Adware, Spyware & Virus free”. However, do not get tricked by this because it means that FileOpener does not spread other suspicious programs but does not mean that it’s not an adware itself. In addition to direct distribution (via official website), this adware may spread via software bundles, i.e. attached to various freewares as an ‘optional download’. If it manages to infiltrate your computer this way, you may notice that your web browser loads websites slower that it used to. Even more, tons of commercial advertisements may start showing on every website that you visit. They may appear in such forms as pop-ups, pop-unders, baners and in-text links. Most of them contain information about various deals and discounts. However, none of the FileOpener ads should be clicked on because they may be filled with sponsored links and cause redirects to unwanted websites. Besides, these advertisements are not randomly delivered. In order to prepare ‘Ads by FileOpener’, its developers may install tracking cookies on each of your web browser (Google Chrome, Mozilla Firefox or Internet Explorer) and collect information related to your browsing habits. Thus, it’s obvious that the plug-in may appear to be not that useful as promised. If you want to prevent FileOpener redirects and other issues, we highly recommend you to check run a full system with a reputable anti-spyware, such as Reimage (Windows OS) or Webroot SecureAnywhere AntiVirus (Mac OS X).

How can FileOpener hijack my computer?

As we have already mentioned, File Opener has the official website and can be downloaded right there. Nevertheless, it’s developers apply other methods, such as ‘bundling’, in order to distribute the app for a wider audience. Unfortunately, by ‘bundling’, FileOpener can infiltrate computers without being noticed and negatively surprise their owners. Since ‘bundling’ means that various third-party browser add-ons, plug-ins, toolbars, and extensions (e.g. Rock Turner, Unico Browser, GoingGo, Record Checker, etc.) are attached to other freewares and spread in one pack. Therefore, the only way to prevent installing unwanted programs on computers is to check freewares carefully and opt out of attachments that they carry. In order to do that, you should select Advanced or Custom installation, monitor the installation carefully, and deselect ‘optional download’.
