What is Split Files?
While inspecting suspicious websites, our researchers found a deceptive page promoting a malicious download assistant. Following installation on our test machine, we learned that it was bundled with a variety of harmful software, including Split Files (alternatively titled Split Files Setup). This application operates as adware and may have additional dangerous functionalities.
Split Files adware overview
Adware stands for advertising-supported software. It enables the placement of advertisements on various interfaces. This third-party graphical content (e.g., pop-ups, banners, coupons, overlays, etc.) promotes online scams, untrustworthy/harmful software, and even malware. Once clicked on, some intrusive ads can perform downloads/installations without user consent.
It must be mentioned that any genuine content encountered through these adverts is most likely promoted by scammers abusing its affiliate programs in order to obtain illegitimate commissions.
Adware might not run intrusive ad campaigns if certain conditions are unsuitable, e.g., incompatible browser/system specs, particular sites not visited, etc. Even if Split Files does not display advertisements – its presence on a system endangers device and user safety.
Some apps within this classification also have browser-hijacking and/or data-tracking abilities, and this might be true of Split Files. Advertising-supported software usually targets the following data: browsing and search engine histories, account log-in credentials, personally identifiable details, finance-related information, and so on. The collected data can be monetized via sale to third-parties or otherwise abused for profit.
In summary, the presence of software like Split Files on devices may result in system infections, severe privacy issues, financial losses, and even identity theft.

Advertising-supported software typically appears ordinary and useful. It also promises a wide range of functionalities. However, these features seldom work as advertised, and in most cases – they are utterly nonoperational. Keep in mind that whether an app's features work – is not an indicator of its legitimacy or safety.
How did Split Files install on my computer?
We downloaded an installer bundled with Split Files from a deceptive webpage. Advertising-supported software is promoted on a variety of misleading (yet potentially legitimate-looking) websites. Most users enter them through redirects caused by misspelled URLs, pages using rogue advertising networks, spam browser notifications, intrusive ads, or installed adware (with browser force-opening capabilities).
The software can also be bundled with various ordinary programs. Downloading from untrustworthy sources (e.g., freeware and third-party sites, P2P sharing networks, etc.) and rushing installation processes (e.g., using "Easy/Quick" settings, etc.) – increase the risk of allowing bundled content into the system.
Intrusive advertisements are used to spread adware as well. When clicked on, some of these adverts can execute scripts to perform stealthy downloads/installations.
How to avoid installation of adware?
We strongly recommend researching software and downloading it only from official/verified channels. It is essential to approach installation with care, e.g., by reading terms, exploring possible options, using the "Custom/Advanced" settings, and opting-out of supplementary apps, extensions, features, etc.
Another recommendation is to exercise caution while browsing since fraudulent and malicious content typically appears legitimate. For example, intrusive ads may look harmless yet redirect to highly questionable websites (e.g., adult-dating, pornography, gambling, etc.).
In case of encounters with such advertisements and/or redirects, inspect the system and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with Split Files, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
