How to remove ValueKnow from Mac?

What is ValueKnow?

ValueKnow is the name of a potentially unwanted application (PUA) which is classified as adware. As a rule, adware-type applications are designed to generate revenue for their developers by feeding users with various advertisements. This particular app is capable of accessing and collecting various information too. Also, it promotes Safe Finder website by opening it through akamaihd.net. Apps like ValueKnow are called PUAs because users tend to download and install them unintentionally.

ValueKnow adware

One of the main reasons not to download and install ValueKnow is that it can read sensitive information from browsers. It targets data such as passwords, phone numbers, credit card details and other confidential information. It is common that apps of this type gather browsing data (e.g., IP addresses, geolocations, entered search queries, addresses of visited pages, etc.) too. Their developers can misuse gathered information by selling it to third parties (potentially cyber criminals), making fraudulent purchases, transactions, stealing identities, accounts, etc. Users who have ValueKnow on a browser and operating system installed may suffer financial loss, problems related to browsing safety, online privacy, become victims of identity theft, and other serious problems. Another reason not to have such apps installed is because they feed users with intrusive ads that usually are being displayed in forms of coupons, banners, surveys, pop-ups, and so on. Users who click those advertisements get end up on untrustworthy websites or cause downloads and/or installations of other PUAs.

Applications like ValueKnow often are advertised as useful, legitimate applications that supposed to improve web browsing experience, deliver some features, etc. Although, it is common that such apps are completely useless and cause various problems. Therefore, if there is any adware installed on a browser and/or operating system, then it should be removed from it right away. Some examples of other adware-type apps are UpgradeAssist, GeneralLaunch and EssentialPanel.

How did ValueKnow install on my computer?

Most of the times users download and/or install adware or other PUAs by accidentally (or intentionally) clicking deceptive advertisements, or when those apps are included in setups of other programs as additional offers. Usually offers to download and/or install additional apps are hidden in "Custom", "Advanced" or similar settings of download and/or installation setups. When users download and/or install programs without checking and changing those settings, they often allow for PUAs to be downloaded and/or installed too. Additionally, PUAs can be downloaded/and or installed by clicking deceptive advertisements that cause it by runing certain scripts.

How to avoid installation of potentially unwanted applications?

Unwanted downloads and installations can be avoided by downloading programs only from official websites and via direct links and not through third party downloaders, installers, Peer-to-Peer networks (e.g., torrent clients, eMule), questionable websites, or other similar channels. Also, it can be avoided by always checking "Custom", "Advanced" and other similar settings of any download or installation setup and declining offers to download or install additionally included software. Furthermore, ads thart appear on shady pages often cause redirects to untrustworthy (and potentially malicious) websites or downloads, installations of various PUAs. Therefore, they should not be clicked. If there are any unwanted applications (extensions, plug-ins, and add-ons) already installed on a browser, then they should be uninstalled from it as soon as possible. The same applies to programs of this kind that are installed on the operating system. If your computer is already infected with ValueKnow, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
