How to remove ProcessSign from Mac?

What is ProcessSign?

ProcessSign is one of the many potentially unwanted applications (PUAs) that are categorized as adware. Adware is a type of software that is designed to serve various intrusive advertisements. Quite often apps of this type operate as information tracking tools as well (they gather various data). It is worthwhile to mention that users often download and install PUAs unknowingly, inadvertently.

ProcessSign adware

More often than not adware like ProcessSign is designed to feed users with advertisements that are displayed in forms of banners, coupons, surveys, pop-ups, and other ads. It is common that those ads conceal contents of visited pages and, if clicked, open questionable, potentially malicious pages cause downloads, installations of unwanted apps by running certain scripts. Quite often apps of this type are designed to gather various information related to user's browsing habits as well. They can collect details like addresses of visited pages, entered search queries, IP addresses, geolocations, and other browsing data. Research shows that ProcessSign can read sensitive information from websites such as passwords, phone numbers, credit card details, and other sensitive information. Its developers may misuse such information to make fraudulent purchases, transactions, steal identities, sell gathered information to third parties (potentially cyber criminals), and/or perform other malicious actions. ProcessSign'S users may suffer financial loss, become victims of identity theft, experience problems related to browsing safety, online privacy and other serious issues. Therefore, ProcessSign or any other similar app should never be downloaded and installed.

ProcessSign is similar to TaskBrowser, MoreResults, AddUpgrade and many other adware-type applications. As a rule, software of this type is designed to display intrusive, often deceptive advertisements. Also, it is common that adware operates as information tracking tool. Quite often adware-type applications are advertised as legitimate, useful. However, most of them do not operate as they supposed to, do not deliver any features or other value and cause a variety of issues.

How did ProcessSign install on my computer?

In most cases users download and/or install PUAs unintentionally: by clicking deceptive advertisements that designed to execute certain scripts, orby downloading and/or installing programs that have PUAs included in their setups. Typically, PUAs are included in various download and/or installation setups as additional offers and can be found in their settings like "Custom", "Advanced", etc. This distribution method of PUAs is called "bundling", it is being used to trick users into downloading and/or installing unwanted apps together with other, desired programs. When users leave setup's settings unchanged, they often allow for PUAs to be downloaded and/or installed alongside with programs that they downloaded and/or installed intentionally.

How to avoid installation of potentially unwanted applications?

It is recommended to download all software only from official websites and through direct links. Channels like third party downloaders, installers, Peer-to-Peer networks (e.g., torrent clients, eMule), unofficial pages, etc., should not be used as tools to download or install any software. Quite often they are used to distribute unwanted, potentially malicious apps. Furthermore, downloads and installations should not be completed without checking setup's settings like "Custom", "Advanced" and declining offers to download and/or install additional, unwanted apps. Intrusive ads that appear on various shady pages can be designed to open untrustworthy websites or download, install unwanted software. Therefore, it is not safe to click such ads. If there are some unwanted, unknown apps (extensions, add-ons or plug-ins) installed on a web browser, then they should be uninstalled from it as soon as possible. The same should be applied to software of this kind that is installed on the operating system. If your computer is already infected with ProcessSign, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
