How to remove UpdaterSync adware from Mac?

What is UpdaterSync?

UpdaterSync is an adware-type app with browser hijacker qualities. It operates by running intrusive advertisement campaigns (i.e., delivering various ads) and making modifications to browsers - in order to promote fake search engines. Due to the dubious methods used to distribute UpdaterSync, it is also categorized as a PUA (Potentially Unwanted Application). Most PUAs have data tracking abilities, which are employed to collect browsing-related information.

UpdaterSync adware

Adware enables the placement of pop-ups, banners, coupons, and other intrusive adverts - typically on any visited website. These advertisements severely cripple the browsing experience by slowing down the browsing speed and overlaying webpage content. In addition, intrusive ads pose a threat to device and user safety. Upon being clicked, the adverts redirect to untrustworthy/malicious sites and some can stealthily download/install software (e.g., PUAs).

Browser hijackers reassign browsers' homepage, default search engine, and new tab/window URLs - to the addresses of fake web searchers. Hence, with a browser hijacker installed: every single search query typed into the URL bar and new browser tab/window opened - redirect to the promoted address. Illegitimate search engines are usually unable to provide accurate and/or safe search results. In most cases, they cannot generate search results at all, so fake web searchers tend to redirect to (or cause redirection chains ending with) Google, Yahoo, Bing, and other legitimate search engines. Furthermore, browser hijackers can undo any changes users try to make to their browsers and/or restrict/deny access to browser settings outright. Therefore, recovering a hijacked browser is impossible without removing the software affecting it.

Most PUAs (adware and browser hijackers included) can track data. They monitor browsing activity (visited URLs, viewed pages, searched queries, etc.) and collect personal information extracted from it (IP addresses, geolocations, and other details). This vulnerable data is then monetized by being shared with and/or sold to third parties (potentially, cyber criminals). In summary, unwanted software can cause system infections, severe privacy issues, financial losses, and even identity theft. To ensure device integrity and user privacy, all suspicious applications and browser extensions/plug-ins must be eliminated immediately upon detection.

ProcessBrandExpandedTask, and CacheImprovment are a couple examples of adware-type applications. They appear ordinary and harmless. Users are enticed into download/installation with offers of various "useful" and "advantageous" functionalities. However, the advertised features are rarely operational. In fact, this applies to nearly all PUAs. The only goal of unwanted apps is to generate revenue for the developers. Hence, instead of delivering on any promises, PUAs can run intrusive advertisement campaigns, hijack browsers, cause redirects, collect private data.

How did UpdaterSync install on my computer?

PUAs are spread through download/installation setups of other products. This false marketing technique of packing regular software with unwanted or malicious additions - is termed "bundling". Rushed download/installation processes (e.g., skipped steps and sections, used pre-set options, etc.) increase the risk of inadvertently allowing bundled content into the system. Intrusive adverts are also used to proliferate PUAs. When clicked on, the ads can execute scripts to download/install these applications without user consent. PUAs may have "official" promotional/download pages as well.

How to avoid installation of potentially unwanted applications?

It is advised to research products to verify their legitimacy prior to download/installation and/or purchase. All downloads must be done from official and verified sources. Untrustworthy download channels, e.g., unofficial and free file-hosting sites, Peer-to-Peer sharing networks, and other third party downloaders - commonly offer bundled and/or dangerous content. Download and installation processes must be approached with caution; that includes - reading terms, exploring all possible options, using the "Custom/Advanced" settings and opting-out from additional apps, tools, features, and so on. Intrusive advertisements appear legitimate and innocuous; however, they redirect to highly questionable websites (e.g., adult-dating, pornography, gambling, etc.). In case of encounters with ads and/or redirects of this type, the system must be inspected and all suspect applications and browser extensions/plug-ins detected - removed from it without delay. If your computer is already infected with UpdaterSync, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
