What is Best Files Downloader?

Best Files Downloader is a rogue browser extension that our research team found while looking through dubious software-promoting sites. This extension is endorsed as a download management tool. However, our analysis revealed that Best Files Downloader operates as advertising-supported software (adware).

Best Files Downloader adware overview

Adware is designed to display advertisements on visited sites and/or different interfaces. These ads promote online scams, untrustworthy/harmful websites and software, and even malware. Additionally, some intrusive adverts can be triggered (by being clicked) to make stealthy downloads/installations.

It is pertinent to mention that any legitimate products encountered via these advertisements are unlikely to be promoted by their developers. Instead, this promotion is undertaken by scammers' abusing the products' affiliate programs to obtain illegitimate commissions.

It is noteworthy that advertising-supported software may require specific conditions to deliver intrusive advertisement campaigns (e.g., compatible browser/system, visits to particular websites, etc.). However, regardless of whether Best Files Downloader (or other adware) displays adverts - its presence on a system endangers device/user safety.

Furthermore, Best Files Downloader has data tracking abilities. Targeted information may include: browsing and search engine histories, personally identifiable details, usernames/passwords, financial/banking data, etc. The gathered data can then be shared with and/or sold to third-parties (potentially, cyber criminals).

In summary, the presence of software like Best Files Downloader on devices can lead to system infections, severe privacy issues, financial losses, and even identity theft.

Adware examples

We have analyzed thousands of advertising-supported software samples; Easy Tuning Videosframe orderFiles Download Fast, and paint page are just some examples of our newest finds. Adware usually appears legitimate and offers "handy" features. However, these functions rarely work as promised, and in most cases - they are nonoperational.

How did Best Files Downloader install on my computer?

We acquired Best Files Downloader from its "official" promotional webpage. Additionally, adware is pushed through scam sites. Users typically access these websites via redirects caused by pages using rogue advertising networks, spam browser notifications, mistyped URLs, intrusive adverts, or installed adware (with browser force-opening capabilities).

Intrusive advertisements proliferate advertising-supported software as well. When clicked on, some of these ads can execute scripts to make stealthy downloads/installations.

Adware can also be bundled (packed together) with ordinary programs. Download from dubious channels (e.g., unofficial and freeware sites, P2P sharing networks, etc.) and rushed installations increase the risk of allowing bundled content into the system.

How to avoid installation of adware?

We highly recommend researching software and downloading only from official/verified sources. When installing, it is crucial to read terms, study available options, use the "Custom/Advanced" settings, and opt-out of all additions.

We advise exercising caution when browsing as fraudulent and malicious content usually appears legitimate. For example, intrusive advertisements look harmless yet redirect to questionable websites (e.g., gambling, pornography, adult-dating, etc.).

If you experience such ads/redirects, check the system and immediately remove all suspect applications and browser extensions/plug-ins. If your computer is already infected with Best Files Downloader, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
