How to remove OpticalUpdater adware from the operating system?

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

What is OpticalUpdater?

OpticalUpdater is an adware-type application with browser hijacker traits. Following successful infiltration, it runs intrusive advertisement campaigns and promotes fake search engines by modifying browser settings. Additionally, most adware-types and browser hijackers collect browsing-related information.

Typically, users download/install OpticalUpdater unintentionally; hence, this app is classified as a PUA (Potentially Unwanted Application). This piece of software has been observed being spread via fake Adobe Flash Player updates. It is noteworthy that illegitimate software updaters/installers are also used to proliferate malware (e.g., trojans, ransomware, etc.).

Adware enables the placement of pop-ups, banners, coupons, surveys, and other intrusive ads - typically on any visited website (or different interfaces). These adverts severely diminish the browsing experience by slowing down the browsing speed and limiting site visibility (by overlaying page content).

Furthermore, upon being clicked, intrusive advertisements redirect to various untrustworthy/malicious websites and some can stealthily download/install software (e.g., PUAs). Browser hijackers assign fake web searcher addresses as browsers' homepage, default search engine, and new tab/window URLs.

With such a piece of software installed: every new browser tab/window opened and web search done via the URL bar - redirect to the promoted address. Illegitimate search engines seldom can provide search results, so they redirect (or cause redirection chains ending with) Yahoo, Bing, Google, and other genuine ones.

Browser hijackers can also undo any changes users try to make to their browsers and/or restrict/deny access to the browser settings. Therefore, recovering an affected browser is impossible without removing the software hijacking it. What is more, most PUAs (adware and browser hijackers included) have data tracking abilities.

They monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and gather vulnerable information extracted from it (IP addresses, geolocations, and even personally identifiable details). The gathered data is then monetized by being shared with and/or sold to third-parties (potentially, cyber criminals).

To summarize, presence of unwanted apps on devices can lead to system infections, serious privacy issues, financial losses, and identity theft. To protect device and user safety, all suspect applications and browser extensions/plug-ins must be eliminated immediately upon detection.

StandBoostFormatBoostOperativeUnit, and SkilledPanelSearch are some examples of other apps within the adware classification. They appear ordinary and harmless. Users are lured into download/installation with offers of "handy" features.

However, the advertised functionalities are usually nonoperational. In fact, this applies to nearly all PUAs. The sole purpose of unwanted software is to generate profit for the developers; hence, functionality and user privacy are irrelevant. PUAs are designed to deliver intrusive ad campaigns, hijack browsers, cause redirects, and collect private data.

How did OpticalUpdater install on my computer?

PUAs are spread through downloaders/installers of other software. This deceptive marketing tactic of packing regular products with unwanted or malicious additions - is named "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 advertisements proliferate PUAs as well. When clicked on, the ads can execute scripts to download/install these applications without user consent. PUAs may also have "official" promotional/download webpages.

How to avoid installation of potentially unwanted applications?

It is advised to always research software prior to download/installation and/or purchase. Additionally, all downloads must be done from official and verified sources. Dubious download channels, e.g., unofficial and free file-hosting sites, Peer-to-Peer sharing networks, and other third-party sources - often offer bundled content.

Download and installation processes have to be treated with caution. Therefore, it is recommended to read terms, explore possible options, use "Custom/Advanced" settings and opt-out from supplementary apps, tools, features, and other additions.

Intrusive adverts appear legitimate and innocuous; however, they redirect to various questionable websites (e.g., gambling, pornography, adult-dating, etc.). In case of encounters with such ads and/or redirects, the device must be inspected and all suspicious applications and browser extensions/plug-ins detected - removed from it without delay.

If your computer is already infected with OpticalUpdater, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
