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 and, therefore, this app is classified as a Potentially Unwanted Application (PUA).

This piece of software has been observed being spread via fake Adobe Flash Player updates. Note that bogus 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 ads significantly diminish the browsing experience by reducing browsing speed and limiting site visibility (by overlaying page content). Furthermore, when clicked, intrusive advertisements redirect to various untrusted/malicious websites and some can stealthily download/install software (e.g., PUAs).

Browser hijackers assign fake searcher addresses as the homepage, default search engine, and new tab/window URLs. With this software installed, every new browser tab/window opened and web search done via the URL bar redirects to the promoted address. Bogus search engines seldom can provide search results, and so they redirect (or cause redirection chains ending with) Yahoo, Bing, Google, and other genuine sites.

Browser hijackers can also undo any changes users try to make to their browsers and restrict/deny access to the browser settings. Therefore, recovering an affected browser is impossible without removing the software hijacking it.

Furthermore, most PUAs (adware and browser hijackers included) have data tracking capabilities. 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 sharing with and/or selling to third-parties (potentially, cyber criminals).

To summarize, the presence of unwanted apps on devices can lead to system infections, serious privacy issues, financial loss, 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 often appear ordinary and harmless, and users are lured into download/installation with offers of "useful" features, however, the advertised functionality is usually nonoperational. In fact, this applies to most PUAs. The sole purpose of this unwanted software is to generate profit for the developers.

PUAs deliver intrusive ad campaigns, hijack browsers, cause redirects, and collect private data.

How did OpticalUpdater install on my computer?

PUAs are often downloaded/installed together with other products. This deceptive marketing technique of pre-packing regular software with unwanted or malicious additions is called "bundling".

By rushing through download/installation of software (e.g. ignoring terms, skipping steps and sections, using "Quick/Express" settings, etc.) many users risk unintentionally allowing bundled content into their devices. Intrusive advertisements proliferate PUAs as well. When clicked, the ads can execute scripts to download/install these applications without users' permission.

Some PUAs have "official" download web pages from which they can be downloaded.

How to avoid installation of potentially unwanted applications

You are advised to research all software before download/installation. Use only official and verified download channels. Unofficial and free file-hosting websites, Peer-to-Peer sharing networks (BitTorrent, Gnutella, eMule), and other third party downloaders commonly offer harmful and bundled content, and are therefore untrusted and should be avoided.

When downloading/installing, read the terms, study all possible options, use the "Custom/Advanced" settings and opt-out of additional apps, tools, features, and so on.

Intrusive advertisements typically seem legitimate, however, they can redirect to dubious and malicious sites (e.g. gambling, pornography, adult-dating, and many others). If you encounter ads or redirects of this kind, inspect the system and remove all dubious applications and browser extensions/plug-ins immediately.

Installed programs must be activated and updated with tools or implemented functions that are provided by the official developers. No other third party, unofficial tools should be used.

Note that it is illegal to activate licensed software with ‘cracking’ tools. Files and programs should be downloaded from official websites and via direct download links. Avoid third party installers and the tools/sources mentioned above.

Do not open website links or files in irrelevant emails that are received from unknown, suspicious addresses. These bogus emails are often disguised as official and important. Regularly, scan your computer with reputable, up-to-date antivirus or anti-spyware software.

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