How to remove FrequencySkill adware from the operating system

What is FrequencySkill?

FrequencySkill is an adware-type application that shares traits with browser hijackers. Following successful installation, this app runs intrusive advertisement campaigns (i.e. delivers various ads), makes modifications to browser settings and promotes fake search engines.

FrequencySkill promotes 0yrvtrh.com on Safari browsers and search.adjustablesample.com on Google Chrome browsers. Furthermore, most adware-type apps and browser hijackers monitor users' browsing activity. Due to the dubious methods used to proliferate FrequencySkill, it is also classified as a Potentially Unwanted Application (PUA).

Adware enables the placement of pop-ups, banners, coupons, surveys, full-page and other intrusive advertisements, typically on any visited website. These ads significantly diminish the browsing experience, since they overlay web page content and restrict browsing speed.

Furthermore, when clicked, intrusive ads redirect to untrusted/malicious sites and some can even stealthily download/install rogue software (e.g. PUAs). Browser hijackers operate by reassigning the homepage, default search engine and new tab/window URLs to the addresses of fake search engines.

FrequencySkill also makes these alterations to browsers to promote 0yrvtrh.com (Safari) and search.adjustablesample.com (Google Chrome). Therefore, with a browser hijacker installed, each new browser tab/window opened and web search made via the URL bar redirects to the promoted address.

In the case of FrequencySkill, either to 0yrvtrh.com or to search.adjustablesample.com. Fake search engines are rarely able to provide search results, and so they tend to redirect to Yahoo, Bing, Google and other genuine sites. Additionally, browser hijackers can undo any changes users attempt to make to their browsers, if they permit access to the settings in the first place.

Therefore, recovering a hijacked browser is impossible without removing the software affecting it. As mentioned, most PUAs (adware and browser hijackers included) have data tracking capabilities.

They can monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect personal information extracted from it (IP addresses, geolocations and other details). To summarize, the presence of unwanted apps on devices can lead to system infections, financial loss, serious privacy issues and even identity theft.

To ensure device integrity and user safety, all suspect applications and browser extensions/plug-ins must be eliminated without delay.

DesktopCoordinator, AssistiveDisplaySearch, SkillFrequency and OnlineToolSearch are some examples of other apps within the adware category. They may seem legitimate, and often entice users into download/installation with offers of "useful" functions, however, the features promised are seldom operational. In fact, this applies to most PUAs.

The only purpose of this unwanted software is to generate revenue for the developers. Regular users receive no real value and can instead experience serious problems. PUAs deliver intrusive ads, make modifications to browsers, cause redirects and gather personally identifiable information.

How did FrequencySkill install on my computer?

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

Rushing downloads/installations (e.g. ignoring terms, skipping steps, etc.) increases the risk of inadvertently allowing bundled content into the system. Certain PUAs have "official" promotional web pages. Intrusive advertisements proliferate these applications as well. Once clicked, they can execute scripts to download/install PUAs without users' consent.

How to avoid installation of potentially unwanted applications

It is important to research all software prior to download/installation. All downloads must be done from official and trustworthy sources, since dubious channels, including unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders, commonly offer bundled content.

When downloading/installing, read the terms, study all available options, use the "Custom" or "Advanced" settings and opt-out of additional apps, tools, features, and so on. Intrusive ads may seem legitimate and harmless, however, they can redirect to dubious sites (e.g. gambling, pornography, adult-dating, etc.).

If you encounter ads or redirects of this kind, check all devices and immediately remove all suspicious applications and browser extensions/plug-ins from them. If your computer is already infected with FrequencySkill, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
