How to remove FrequencySignal adware from Mac?

What is FrequencySignal adware?

FrequencySignal is an adware-type application with browser hijacker traits. It operates by running intrusive advertisement campaigns, makes alterations to browser settings and promotes fake search engines. FrequencySignal promotes (via akamaihd.net) Safe Finder. Additionally, most adwares and browser hijackers have data tracking abilities, which are employed to spy on users' browsing activity. Hence, it is highly likely that FrequencySignal has such functionality as well. Due to the questionable techniques used to distribute FrequencySignal, it considered to be a PUA (Potentially Unwanted Application).

FrequencySignal adware

Adware enables the placement of pop-ups, banners, coupons, surveys and other intrusive ads - typically, on any visited website. These advertisements diminish the browsing experience, since they overlay page content and slow down the browsing speed. When clicked on, they redirect to various unreliable/malicious webpages and some can even execute scripts to stealthily download/install software (e.g. PUAs). Browser hijackers assign the addresses of illegitimate web searchers as browsers' homepage, default search engine and new tab/window URLs. Therefore, new browser tabs/windows opened and every single web search done via the URL bar - redirect to the promoted address. FrequencySignal promotes Safe Finder through akamaihd.net. Fake web searchers are rarely able to generate search results, so they tend to redirect (or cause redirection chains leading) to Google, Yahoo, Bing and other legitimate search engines. Furthermore, browser hijackers can reset any changes made user attempt to make to their browser and/or deny access to the browser's settings outright. What is more, most PUAs (e.g. adware, browser hijackers, etc.) can track data. They can monitor users' browsing habits (URLs visited, pages viewed, search queries typed, etc.) and gather personal information (IP addresses, geolocations and other details). The collected data is usually shared with third parties (potentially, cyber criminals), seeking to misuse it for profit. In summary, presence of unwanted apps on devices can result in system infections, financial losses, serious privacy issues and even identity theft. To protect device integrity and user safety, it is strongly advised to eliminate all suspicious applications and browser extensions/plug-ins without delay.

SoftwareHandlerProductiveOperation and ScalableSkill are a few examples of other adwares. They appear legitimate and harmless. Users are enticed into download/installation with a broad range of "useful" and "advantageous" functionalities. However, the promised features are seldom operational. This applies to practically all PUAs. Unwanted applications have just one goal - to generate revenue for the developers; to users - they are worthless and can even cause various issues. PUAs are designed to run intrusive ad campaigns, force-open untrustworthy/malicious sites, hijack browsers and collect private information.

How did FrequencySignal install on my computer?

PUAs proliferate through download/installation setups of other products. This false marketing technique of pre-packing ordinary software with unwanted or malicious additions - is called "bundling". By rushing through download/installation processes (e.g. by ignoring terms, skipping steps, using pre-set options, etc.) - increase the risk of unintentionally allowing bundled content into the system. Some PUAs have "official" promotional webpages, from which they can be downloaded. Intrusive advertisement campaigns can infiltrate these apps into systems as well. Once clicked on, they can execute scripts to download/install PUAs without user permission.

How to avoid installation of potentially unwanted applications?

It is recommended to research software to verify its legitimacy, before download/installation and/or purchase. Only official and verified download channels must be used. Unofficial and free file-hosting websites, P2P sharing networks (BitTorrent, eMule, Gnutella, etc.) and other third party downloaders - commonly offer deceptive and/or bundled content, due to this - they are deemed to be untrustworthy. When downloading/installing, it is important to read terms, explore all possible options, use the "Custom/Advanced" settings and opt-out from additional apps, tools, features, and so on. Intrusive adverts usually appear legitimate, however they redirect to questionable pages (e.g. gambling, pornography, adult-dating, etc.). Should users encounter ads/redirects of this type, they must inspect the system and immediately remove all dubious applications and likewise suspect browser extensions/plug-ins from it. If your computer is already infected with FrequencySignal, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
