“FDownloader” is classified as a Potentially Unwanted Program (PUP) that after being installed on your machine affects registry entries and browser settings. It then can collect important personal data and display many unwanted advertisements. The user might be redirected to fake product pages which aim is to generate revenue per every click or by the purchase of such a product.


FDownloader – How Did I Get It?

FDownloader usually gets into your system through third-party installers. It can sneak into your computer without your knowledge, by concealing itself in freeware installations and bundled packages. In these packages, additional components for installation are not always disclosed in a proper manner, and people get tricked into installing potentially unwanted programs such as this “FDownloader”. Sometimes that can be avoided by clicking on the “Advanced” or “Custom” option in an installation setup to see what will be installed.

Another way of getting this adware is by installing it as a free application or browser extension for popular browsers like Mozilla Firefox, Google Chrome, Internet Explorer and etc. Also, it can get in your machine through drive-by-downloads via outdated browser or Flash Player plugin.

FDownloader – More About It

FDownloader claims that it is a legitimate program that will help you with managing your downloads, especially your video downloads and the free converting of those videos into other formats. Those are false claims, because the program has only two main options “Download site” and “Download video”. Videos that you try to download contain one file that is really small in size and there is no converter involved – just the file type extension is renamed, and selecting the option for converting or not gets you an unusable file. Trying to “Download a site” also gets you one small-sized file which if you choose to be a text file it can open some code from the page but serves you no purpose.

Moreover, FDownloader has this written in their license agreement:

  • “Use of Cookies – 3. Software Provider uses various technologies to collect and store information concerning the Internet usage habits of the User, by using tracking technologies such as cookies or anonymous identifiers, pixels, and beacons, deployed to User’s Internet device.”
  • “Software Provider mainly uses information it gathers in order to (i) provide User with content such as targeted advertisements promotional and marketing material…”


So the user agrees to be targeted with advertisements upon clicking “Agree” when installing the application from the site or by simply installing the program from bundled freeware and not knowing about the program or its license agreement at all.

When this very suspicious program is installed on your computer, it can collect information such as your IP address, the websites you visit, specific pages you view, your search queries, and etc. Such information might contain personally identifiable details and according to the agreement above – it is shared with third party companies, who can abuse it to generate revenue for their sites.

After the adware is on your machine it modifies registry entries and can also modify browser settings, in order to potentially add an extension or a plug-in to it as well. When you are browsing websites intrusive ads could appear such as discount coupons, pop-up and pop-under ads, banners, and other promotional products and search suggestions and even hyperlinks might be embedded into the text of popular webpages. If any of those ads are interacted with, the user could be redirected to a site with malicious content or an advertisement page of a fake product.

The main aim of Fdownloader is to generate as much traffic as possible to domains, which could easily be monetized through an online marketing platform. Also the user can be tricked into buying one of the advertised, suspicious products which might not help at all, and even infect the computer with similar PUPs.
