How to uninstall ExtendedTransaction adware from the operating system?

Also Known As: Ads by ExtendedTransaction
Type: Mac Virus
Damage level: Medium

What is ExtendedTransaction?

ExtendedTransaction is an adware-type application with browser hijacker qualities. Following successful installation, this piece of rogue software delivers intrusive advertisement campaigns and modifies browser settings to promote fake search engines. Additionally, ExtendedTransaction likely has data tracking abilities.

Due to the questionable methods used to distribute adware and browser hijackers, they are also classified as PUAs (Potentially Unwanted Applications). It is worth noting that proliferation via fake Adobe Flash Player updates is common for software like ExtendedTransaction.

ExtendedTransaction adware

ExtendedTransaction adware in detail

Adware enables the placement of third-party graphical content on any visited website and/or different interfaces. This software can deliver pop-ups, coupons, banners, surveys, full-page, and other intrusive advertisements. These ads seriously diminish the browsing experience and pose a threat to device/user safety.

Intrusive adverts can be misleading, untrustworthy, and even dangerous. They endorse various sale-based pages (of both legitimate and fraudulent products), unreliable, rogue, deceptive/scam, compromised, and malicious sites. Some of these advertisements can stealthily download/install software (e.g., PUAs) - when they are clicked on.

Browser hijackers reassign browsers' homepage, default search engine, and new tab/window URLs - to fake web searcher addresses. Hence, with this piece of software installed: new browser tabs/windows opened and search queries typed into the URL bar - redirect to the promoted address.

Fraudulent search engines are seldom able to provide search results, so they redirect to Google, Yahoo, Bing, and other legitimate ones. Browser hijackers can reset any changes users try to make to their browsers, and/or deny access to the browser settings. Therefore, restoring an affected browser is impossible without removing the software affecting it.

What is more, most PUAs (adware and browser hijackers included) can track data. Hence, ExtendedTransaction likely has such abilities as well. Information of interest includes: browsing and search engine histories, IP addresses, personally identifiable details, finance-related data, and so forth.

The collected data is then shared with and/or sold to third-parties. In summary, the presence of unwanted apps on devices can lead to system infections, privacy issues, financial losses, and identity theft. To protect device integrity and user privacy, all dubious applications and browser extensions/plug-ins must be removed without delay.

Adware in general

BestForMacDataBoost, and WebResultsTool are a couple examples of applications within the adware classification. They appear legitimate and harmless. Users are enticed into download/installation with promises of "handy" functionalities. However, the features are seldom operational.

In fact, practically all PUAs advertise nonexistent functions. The sole purpose of unwanted software is to generate revenue for the developers; they have no real value to the users. PUAs operate by running intrusive advert campaigns, hijacking browsers, causing redirects, and collecting private and vulnerable information.

How did ExtendedTransaction install on my computer?

PUAs are distributed via downloaders/installers of other products. "Bundling" is the name of this false marketing tactic - pre-packing regular software with unwanted or malicious additions. Rushed downloads/installations (e.g., used "Easy/Express" settings, etc.) increase the risk of allowing bundled content into the device.

Intrusive advertisements are used to proliferate PUAs as well. Once clicked on, the ads can execute scripts to download/install these applications without user permission. Some PUAs may also have "official" promotional sites from which they can be doawnloaded and/or purchased.

How to avoid installation of potentially unwanted applications?

It is recommended to research products prior to download/installation. Additionally, all downloads must be done from official and verified sources. Untrustworthy download channels, e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, and other third-party downloaders - often offer bundled content.

When downloading/installing, it is recommended to read terms, explore available options, use the "Custom/Advanced" settings, and opt-out from additional apps, tools, features, etc. Intrusive adverts appear legitimate; however, they redirect to highly questionable webpages (e.g., gambling, pornography, adult-dating, and many others).

In case of encounters with ads and/or redirects of this kind, the device must be checked and all suspicious applications and browser extensions/plug-ins detected - immediately removed from it. If your computer is already infected with ExtendedTransaction, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
