What is ProcessSign

Targeting macOS users, ProcessSign is a potentially unwanted program falling under the category of adware. This piece of software is designed to sneak-install onto the system and alter browser settings for displaying various banners, pop-ups, coupons, and other intrusive advertising elements. For example, it is spotted to be responsible for the notorious “This process is completed” pop-up. At first glance, the new content like banners supplied by adware while surfing the web may look legitimate or even useful. However, these advertisements are most likely embedded with dubious or malicious links redirecting users to compromised websites (online casinos, fake software download pages, pornography websites, and so forth). Some users may recognize ProcessSign by looking at an icon in Applications that looks like a magnifying loop. Note that software of such is also able to track browser-related information and gather valuable data (e.g., passwords, geolocations, IP addresses, etc.) for monetization purposes. It is evident that users experiencing ProcessSign on their Mac may become subject to identity and security risks if it continues its presence. We, therefore, encourage you to use our tutorial below and delete the unwanted application to prevent the above-mentioned threats and restore safety back on your Mac.

How ProcessSign infected your computer

Adware for both Mac and Windows can be distributed through doubtful pages offering to download something. One of the most popular tricks used by cybercriminals is about claiming your Adobe Flash Player is outdated and needs an “urgent” upgrade. By doing so, many inexperienced users get tricked into downloading fake software, which installs a program different from what was initially claimed. In addition to this, it is also worth mentioning that downloading software from unofficial resources may as well bear the risk of unwanted infections. Pirated or cracked software downloaded in circumvention of license protection may contain supplementary offers, which end up installed without the consent of users. It is sometimes possible to deselect the installation of sponsored programs by looking into “Advanced”, “Custom”, or similar sections, however, not always. The purpose of many unofficial program installers is to make users skip over such sections and not pay attention to details. As a result, many catch inadvertent infections and do not know where they came from.
