What is Simple Files Downloader?

Simple Files Downloader is a rogue browser extension promising to operate as a download management tool. Our researchers discovered it while inspecting dubious download webpages. After analyzing this extension, we determined that Simple Files Downloader is advertising-supported software (adware).

Simple Files Downloader adware overview

Adware is designed to run intrusive advertisement campaigns. In other words, this software can display ads on visited websites and/or other interfaces.

Adware-delivered adverts promote online scams, untrustworthy/harmful sites and software, and even malware. Additionally, some intrusive advertisements can make downloads/installations without user consent - once clicked on.

Note that any legitimate products encountered via these ads are unlikely to be promoted by their actual developers. Instead, this endorsement is undertaken by scammers abusing the products' affiliate programs to acquire illegitimate commissions.

It has to be mentioned that advertising-supported software may require specific conditions to deliver intrusive ad campaigns (e.g., compatible browser/system or user geolocation, visits to particular sites, etc.). However, regardless of whether Simple Files Downloader displays adverts or not, its presence on a system endangers device and user safety.

Furthermore, Simple Files Downloader also has data tracking abilities. Information of interest may include: visited URLs, viewed webpages, searched queries, usernames/passwords, personally identifiable details, credit card numbers, etc. The collected data is then monetized via sale to third-parties.

To summarize, the presence of adware on devices can result in system infections, severe privacy issues, financial losses, and even identity theft.

Adware examples

We have analyzed thousands of advertising-supported software samples; DimScreenAuto Skip AdsAds Skipping Over - are merely a few of our latest finds. Adware typically appears legitimate and handy. Users are lured into download/installation with promises of various functionalities, which are rarely operational.

How did Simple Files Downloader install on my computer?

We obtained Simple Files Downloader from its "official" promotional webpage. In addition to such pages, adware is pushed through scam websites.

Most users access these sites through redirects caused by mistyped URLs, pages using rogue advertising networks, spam browser notifications, intrusive ads, or installed adware (with browser force-opening capabilities).

Advertising-supported software can also be bundled with (packed alongside) regular programs. Download from dubious sources (e.g., unofficial and freeware sites, P2P sharing networks, etc.) and rushed installations increase the risk of allowing bundled content into the system.

Intrusive advertisements proliferate adware as well. Once clicked on, some of these adverts can execute scripts to make downloads/installations without user permission.

How to avoid installation of adware?

We advise researching software and downloading only from official/verified channels. Additionally, installation must be approached with caution, e.g., by reading terms, studying possible options, using the "Custom" or "Advanced" settings, and opting-out of all supplements.

We also recommend exercising caution when browsing since illegitimate and malicious material typically appears harmless. For example, intrusive ads look legitimate yet redirect to highly questionable websites (e.g., gambling, adult-dating, pornography, etc.).

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