What is Best File Converter?

Best File Converter's developers advertise this app as a tool that quickly converts PDF files, images, and audio files. However, it is known that Best File Converter generates advertisements, that is why it is classified as adware. Additionally, this app can read and change all data on websites that its users visit. In most cases, users download and install adware unknowingly. Therefore, apps like Best File Converter are called potentially unwanted applications (PUAs).

Adware is a type of software that generates revenue for its developer by displaying various advertisements (e.g., banners, coupons, pop-up ads, surveys). At the time of the research, ads displayed by Best File Converter were mostly coupons. It is common that ads generated by adware are used to promote questionable pages, in some cases even to distribute (download and/or install) unwanted software. Therefore, it is strongly advisable not to click ads that apps like Best File Converter generate.

Another issue with many apps like Best File Converter is that they collect browsing-related information. For example, IP addresses, geolocations, addresses of visited websites, entered search queries, etc. Although, some of them gather sensitive, personal details as well. What is worse, it is possible that their developers may sell gathered data to third parties (potentially cyber criminals) or monetize it in other ways, which could cause users issues related to online privacy, browsing safety, or other problems.

More adware examples are CheckEmailsQuicker, PBlocker+, and Movie Finder. Pretty often it is advertised as useful software. However, once downloaded and installed, adware displays ads and does not provide any value to its users. If Best File Converter or any other adware is installed on a browser or the operating system, then it should be removed.

How did adware install on my computer?

In most cases, users unintentionally download and/or install PUAs when they are bundled with some other programs. To be more precise, when users finish downloads, installations without declining unwanted offers. Typically, it can be done using available checkboxes or "Advanced", "Custom", "Manual", or other settings. In some cases, users unknowingly cause downloads and/or installations of unwanted applications by clicking deceptive ads that are designed to run certain scripts.

How to avoid installation of potentially unwanted applications?

Programs should be downloaded only from official pages and via direct download links. Peer-to-Peer networks (like eMule, torrent clients), unofficial websites, third party downloaders (and installers), etc., are not trustworthy. Downloads, installations should not be finished without checking and changing (if necessary) "Custom", "Advanced", or other settings. Advertisements on questionable pages should not be clicked as well: it is common that those ads are used to promote websites or to cause unwanted downloads, installations of unwanted apps. Any unwanted, suspicious, unknown extensions, add-ons, or plug-ins that are installed on a browser and/or programs of this kind that are installed on the operating system should be removed. If your computer is already infected with rogue applications, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
