How to uninstall OptimalOrigin adware from the operating system?

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

What is OptimalOrigin?

OptimalOrigin is an adware-type app with browser hijacker qualities. Additionally, due to the dubious techniques used to distribute software products within these classifications, they are also considered to be PUAs (Potentially Unwanted Applications).

OptimalOrigin adware

OptimalOrigin adware in detail

Adware delivers various pop-ups, banners, coupons, surveys, and other intrusive advertisements. They severely diminish the browsing experience and pose a threat to device/user safety. Intrusive ads endorse sale-oriented, untrustworthy, deceptive/scam, and malicious websites. Furthermore, once clicked on, some of these adverts can download/install software (e.g., PUAs) without user consent.

Browser hijackers reassign browsers' homepage, new tab/window, and default search engine URLs - to fake web searcher addresses. Hence, new browser tabs/windows opened and web searches done via the URL bar - redirect to the promoted address.

Fraudulent search engines typically cannot provide search results, so they redirect to Yahoo, Google, Bing, and other legitimate ones. Browser hijackers also use persistence-ensuring methods to prevent users from restoring their browsers.

What is more, most PUAs (adware and browser hijackers included) can track data. Information of interest includes browsing and search engine histories, personally identifiable details, and so on. The gathered data is monetized by being shared with and/or sold to third-parties.

In summary, the presence of unwanted apps on devices can result in system infections, serious privacy issues, financial losses, and identity theft.

Adware in general

CommandImprovementConnectedPlatformSuccessAdvanced, FunctionServer, and LookupDisplay are some examples of apps within the adware classification. They appear legitimate and offer "advantageous" functions, which are seldom operational.

In fact, this applies to practically all PUAs. Unwanted apps can cause redirects, run intrusive ad campaigns, hijack browsers, and collect private data - instead of delivering on any promised features.

How did OptimalOrigin install on my computer?

PUAs are spread using the "bundling" marketing tactic - packing regular software with various additions. Rushed download/installation processes increase the risk of allowing bundled content into the device. Intrusive advertisements proliferate PUAs as well. Once clicked on, the ads can execute scripts to make stealthy downloads/installations. Some PUAs may also have "official" promotional/download pages.

How to avoid installation of potentially unwanted applications?

It is advised to research software and download it only from official/verified sources. Untrustworthy download channels, e.g., unofficial and freeware sites, Peer-to-Peer sharing networks, etc. - often offer bundled content.

When downloading/installing, it is recommended to read terms, study possible options, use the "Custom/Advanced" settings, and opt-out from all supplements. Intrusive advertisements appear legitimate, yet they redirect to highly questionable websites (e.g., gambling, pornography, adult-dating, etc.).

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