How to remove FractionData adware from Mac?

What is FractionData?

FractionData is an adware-type application with browser hijacker traits. Following successful infiltration, this app delivers intrusive advertisement campaigns, makes modifications to browser settings and promotes fake search engines. On Safari browsers FractionData promotes z6airr.com, on Google Chrome browsers - search.trustenviroment.com. Additionally, most adware-types and browser hijackers collect browsing-related information. Due to the questionable methods used to distribute FractionData, it is also deemed to be a PUA (Potentially Unwanted Application). Once the techniques employed in FractionData's distribution is proliferation via fake Adobe Flash Player updates. It is worth mentioning that illegitimate software updaters/installers are used to spread not only PUAs but trojans, ransomware and other malware as well.

FractionData adware

Adware delivers various pop-ups, banners, surveys, coupons, full-page and other intrusive advertisements. They limit website visibility and browsing speed - by overlaying page content. Furthermore, upon being clicked, intrusive ads redirect to unreliable/malicious sites and some can even stealthily download/install software (e.g. PUAs). Browser hijackers assign the addresses of fake web searchers as browsers' homepage, default search engine and new tab/window URLs. Hence, with a browser hijacker installed: every new browser tab/window opened and search query typed into the URL bar - redirect to the promoted address. FractionData promotes z6airr.com (Safari) and search.trustenviroment.com (Google Chrome) in this manner as well. Illegitimate search engines are seldom able to generate search results, so they tend to redirect to Yahoo, Bing, Google and other genuine ones. Browser hijacker can also restrict/deny access to the browser's settings and/or undo any permitted changes made. Therefore, recovering an affected browser is impossible without eliminating the software hijacking it. What is more, most PUAs have data tracking abilities. They can record browsing activity (visited URLs, viewed webpages, searched queries, etc.) and gather personal information extracted from it (IP addresses, geolocations and other details). The collected data is then shared with and/or sold to third parties (potentially, cyber criminals). To summarize, presence of unwanted apps on devices can result in system infections, financial losses, severe privacy issues and even identity theft. To ensure device and user safety, all suspect applications and browser extensions/plug-ins must be removed immediately upon detection.

WebQuestSearchStandartConsoleSearchSearchNetCharacterGoWebSearch and AssistiveFile are some examples of other adware-type applications. They appear legitimate and offer various "handy" features. However, despite how good the advertised functionalities may sound - they are rarely operational. In fact, this is true of practically all PUAs. The only goal of unwanted software is to generate revenue at user expense. Therefore, instead of delivering on any promises, PUAs run intrusive advert campaigns, modify browsers, cause redirects and collect sensitive data.

How did FractionData install on my computer?

PUAs are distributed via download/installation setups of other products. This false marketing tactic of pre-packing regular software with unwanted or malicious additions. By rushing through download/installation processes (e.g. by skipping steps and sections, etc.) - users risk unintentionally allowing bundled content into their devices. Select PUAs have "official" download webpages. Intrusive ads proliferate these applications as well. Once clicked on, the advertisements can execute scripts to download/install PUAs without user consent.

How to avoid installation of potentially unwanted applications?

It is recommended to research software prior to download/installation. Only official and verified download channels must be used. Since untrustworthy sources, like: unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders - commonly offer deceptive and/or bundled content. When downloading/installing, it is advised to read terms, explore all available options, use the "Custom" or "Advanced" settings and opt-out from additional apps, tools, features, etc. Intrusive adverts appear legitimate and harmless, however they redirect to highly questionable webpages (e.g. gambling, pornography, adult-dating, and so on). In case of encounters with ads and/or redirects of this type, users must inspect their devices and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with FractionData, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
