How to eliminate the Ultimate Files Downloader adware
Written by Tomas Meskauskas on (updated)
What is Ultimate Files Downloader?
While inspecting suspicious sites, our researchers discovered the Ultimate Files Downloader browser extension. It is presented as a download management tool. However, our inspection of Ultimate Files Downloader revealed that it operates as advertising-supported software (adware).
Ultimate Files Downloader adware overview
Adware is designed to display advertisements (e.g., pop-ups, surveys, coupons, banners, overlays, etc.) on visited websites and/or other interfaces. These ads endorse online scams, unreliable/hazardous software, and even malware. Some intrusive adverts can execute scripts to perform stealthy downloads/installations upon being clicked.
Note that any legitimate content encountered via these advertisements is unlikely to be promoted by its actual developers. It is most probable that this endorsement is undertaken by scammers who abuse the product's affiliate programs in order to obtain illegitimate commissions.
In addition to running intrusive ad campaigns, Ultimate Files Downloader collects private data. Information of interest may include: URLs visited, webpages viewed, search queries typed, downloads, Internet cookies, usernames/passwords, personally identifiable details, finance-related data, and so forth. The collected data can be sold to third-parties or otherwise abused for profit.
In summary, the presence of advertising-supported software like Ultimate Files Downloader on devices can result in system infections, severe privacy issues, financial losses, and even identity theft.

Adware examples
We have analyzed thousands of adware samples; Tab Manager, Online Radio, SkipAds for Youtube – are just a few of our newest finds.
Software within this classification usually appears legitimate and offers various functionalities. However, adware seldom works as promised, and in most cases – it is utterly nonoperational. It must be stressed that even if a piece of software works as indicated by its promotional material – that is not definitive proof of its legitimacy or safety.
How did Ultimate Files Downloader install on my computer?
We acquired Ultimate Files Downloader from its "official" promotional webpage, and we found a deceptive site endorsing this extension. Most users access these pages via redirects caused by mistyped URLs, websites employing rogue advertising networks, spam browser notifications, intrusive ads, or installed adware (with browser force-opening capabilities).
"Bundling" – packing regular program installers with unwanted/malicious supplements – is also used to proliferate adware. Downloading from untrustworthy channels (e.g., freeware and free file-hosting websites, Peer-to-Peer sharing networks, etc.) and rushing through installation processes – increase the risk of allowing bundled content into the system.
Intrusive advertisements spread advertising-supported software as well. When clicked on, some of these adverts can execute scripts to perform downloads/installations without user consent.
How to avoid installation of adware?
We strongly recommend researching software and downloading it only from official/verified sources. We also advise exercising caution when installing software, e.g., by reading terms, inspecting possible options, using the "Custom/Advanced" settings, and opting out of all additional apps, extensions, etc.
Another recommendation is to be vigilant while browsing since fraudulent and malicious content typically appears legitimate and harmless. For example, while intrusive advertisements may look ordinary and innocuous – they redirect to highly questionable websites (e.g., gambling, pornography, adult dating, etc.).
In case of continuous encounters with such ads/redirects, check the device and immediately remove all dubious applications and browser extensions/plug-ins. If your computer is already infected with Ultimate Files Downloader, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
