How to eliminate OptimizationLaunch adware from your operating system?

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

What is OptimizationLaunch?

OptimizationLaunch is a piece of rogue software classified as adware. It also has browser hijacker traits. Since most users unintentionally download/install apps of this type, they are also categorized as PUAs (Potentially Unwanted Applications).

OptimizationLaunch adware

OptimizationLaunch adware in detail

Adware displays various pop-ups, surveys, banners, coupons, full-page, and other intrusive ads. They can be placed on any visited website and/or different interfaces. Intrusive advertisements seriously diminishing the browsing experience and endanger device/user safety. Once clicked on, the adverts redirect to unreliable/malicious sites, and some can stealthily download/install software (e.g., PUAs).

Browser hijackers reassign browsers' homepage, new tab/window, and default search engine addresses. Therefore, every single new browser tab/window opened and web searches done via the URL bar - redirect to the promoted address.

Fraudulent search engines usually cannot generate search results, so they redirect to Yahoo, Google, Bing, and other legitimate ones. Browser hijackers can also undo any changes users try to make to their browsers, and/or deny access to the browser settings.

Furthermore, PUAs (adware and browser hijackers included) typically have data tracking abilities. Information of interest includes browsing and search engine histories, IP addresses, personally identifiable details, etc. The gathered data is then shared with and/or sold to third-parties (potentially, cyber criminals).

In summary, the presence of unwanted applications on devices can lead to system infections, serious privacy issues, financial losses, and even identity theft.

Adware in general

GeneralAnalogSampleCheck, and ArchivesTransation are a couple examples of adware. It appears legitimate and promises "handy" features, which are seldom operational.

This applies to nearly all PUAs. The sole purpose of these apps is to generate revenue for the developers; hence, instead of delivering on any promises, they can run intrusive ad campaigns, hijack browsers, cause redirects, and gather private data.

How did OptimizationLaunch install on my computer?

PUAs are spread by using the "bundling" technique - packing regular programs with unwanted/malicious supplements. Hence, by rushing through downloads/installations, users risk allowing bundled content into their devices. Intrusive adverts proliferate PUAs as well. Once clicked on, the advertisements can execute scripts to make stealthy downloads/installations. Select PUAs may also have "official" download pages.

How to avoid installation of potentially unwanted applications?

It is recommended to research software and always download it from official/verified sources. Untrustworthy download channels, e.g., Peer-to-Peer sharing networks, unofficial and freeware sites, and other third-party downloaders - often offer bundled content.

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

Should users experience such ads and/or redirects, they must check their devices and immediately remove all suspect applications and browser extensions/plug-ins. If your computer is already infected with OptimizationLaunch, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
