How to eliminate FlexibleFormat adware from your operating system?
Written by Tomas Meskauskas on
What is FlexibleFormat?
FlexibleFormat is an app classified as adware, and it has browser hijacker traits. Due to the dubious methods used to distribute FlexibleFormat and similar software, they are also categorized as PUAs (Potentially Unwanted Applications).
FlexibleFormat adware overview
Adware enables the placement of third-party graphical content (e.g., pop-ups, banners, coupons, surveys, etc.) on visited websites and/or other interfaces. This software can diminish the browsing experience and pose a threat to device/user safety.
The displayed advertisements promote various untrustworthy and malicious sites. What is more, some intrusive ads can download/install software (e.g., PUAs) - when clicked on.
Browser hijackers assign fake search engine addresses as browsers' homepage, default search engine, and new tab/window URLs. Hence, web searches performed via the URL bar and new tabs/windows opened - redirect to the promoted address.
Most fraudulent search engines cannot generate search results, so they redirect to legitimate ones (e.g., Bing, Google, Yahoo, etc.). Browser hijackers also employ persistence-ensuring techniques - to prevent browser recovery.
Most PUAs (adware and browser hijackers included) can track data. The gathered information (e.g., browsing activity, personally identifiable details, etc.) is shared with and/or sold to third-parties.
To summarize, the presence of unwanted software on devices can lead to system infections, serious privacy issues, financial losses, and identity theft.

Adware in general
DefaultEntry, LeadingSystem, LatestStructured, and PrinterCyberSpace are some examples of adware. This software appears innocuous and offers "useful" features that are seldom operational. In fact, this is true of nearly all PUAs. The sole purpose of these apps is to generate revenue at user expense; hence, functionality and user safety are irrelevant.
How did FlexibleFormat install on my computer?
PUAs can be downloaded/installed together with other programs. This false marketing tactic of packing regular software with various additions - is named "bundling". Intrusive ads spread PUAs as well. Once clicked on, the advertisements can execute scripts to make downloads/installations without user permission. PUAs can also have "official" download sites.
How to avoid installation of potentially unwanted applications?
It is strongly recommended to research software and download from official and verified channels. Dubious sources, e.g., unofficial and freeware websites, Peer-to-Peer sharing networks (e.g., Torrent clients, Gnutella, etc.), and other third-party downloaders - commonly offer bundled/harmful content.
Download/Installation processes increase the risk of allowing unwanted/malicious programs into the system. Therefore, it is crucial to read terms, study available options, use the "Custom/Advanced" settings, and opt-out of all additions.
It is just as important to exercise caution when browsing. Intrusive adverts appear legitimate yet redirect to highly questionable sites (e.g., gambling, pornography, adult-dating, etc.).
In case of encounters with such ads/redirects, the system must be checked and all suspicious applications and browser extensions/plug-ins detected - removed without delay. If your computer is already infected with FlexibleFormat, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
