How to remove RunningOptimizer from Mac computers

What is RunningOptimizer?

RunningOptimizer is classified as adware and a browser hijacker, since it feeds users with various advertisements and promotes the 0yrvtrh.com address by changing certain browser settings. Research shows that this app can also access sensitive information from browsers. Generally, users do not download or install apps such as RunningOptimizer (adware, browser hijackers) intentionally. Therefore, they are categorized as potentially unwanted applications (PUAs).

RunningOptimizer adware

Typically, adware-type apps serve banners, coupons, surveys, and pop-up ads that, if clicked, can open dubious websites. In some cases, they may be designed to execute scripts to download or even install PUAs. Most browser hijackers change browser settings such as the address of the default search engine, homepage, and new tab to an address of a fake search engine. Therefore, when a browser hijacker is installed on the browser and/or operating system, users are forced to visit a certain address when they open a browser, new tab or enter search queries into the URL bar. As mentioned, RunningOptimizer promotes 0yrvtrh.com in this manner. When this app is installed on Safari, 0yrvtrh.com redirects to search.yahoo.com, however, when installed on Chrome, it redirects to search.yahoo.com through adjustablesample.com. To stop browsers from opening 0yrvtrh.com or adjustablesample.com, RunningOptimizer must be uninstalled (and other apps that promote rogue addresses) from browsers and operating systems. RunningOptimizer can read sensitive information from browsers such as credit card details, passwords, and telephone numbers. Gathered information can be misused to make fraudulent purchases and transactions, steal personal accounts, identities, and for other malicious purposes. Therefore, you are strongly advised not to trust (download or install) apps such as RunningOptimizer.

There are many apps similar to RunningOptimizer including, for example, OperativeFraction, AdjustableSkill and NetProgress. Adware and browser hijackers are often promoted as useful programs that supposedly include various features, improve the browsing experience, etc, however, few operate as advertised. Generally, they are designed only to feed users with intrusive ads, gather information and change browser settings.

How did RunningOptimizer install on my computer?

In some cases, this happens when users accidentally (or intentionally) click various deceptive ads that run certain scripts, however, it more frequently happens when developers distribute PUAs using a marketing method called "bundling", which is used to trick users into downloading and installing PUAs with other software. This is achieved by including PUAs into the set-ups of other (usually free) programs as 'additional offers'. Usually, these offers can be found (and declined) in "Advanced", "Custom" and other similar settings of the set-ups. Unwanted downloads and installations are caused when users leave all of the aforementioned settings unchecked and unchanged. By leaving default settings unchanged, many users allow PUAs to infiltrate with software that they wish to download and install intentionally.

How to avoid installation of potentially unwanted applications

Programs and files should be downloaded only from official, trustworthy websites and via direct links. It is not safe to download or install via third party downloaders, installers, Peer to-Peer networks (torrent clients, eMule), from dubious, unofficial websites or other similar sources, tools. Check all settings such as "Advanced" and "Custom" and decline offers to download or install unwanted, additionally-included applications. Do not click advertisements on untrusted websites, since they can promote (open) dubious pages or even download and install unwanted software. Remove any unwanted/suspicious extensions, plug-ins or add-ons already installed on the browser. The same applies to software of this kind that is installed on the operating system. If your computer is already infected with RunningOptimizer, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
