What is SystemNotes?

SystemNotes is another malware that affects Safari, Google Chrome, or Mozilla Firefox web-browsers. Similar programs have been bothering Mac users lately, all of them have exactly the same icon – green icon with a magnifying glass but the names are all different. Given that, we can conclude that they were developed by the same authors. As a rule, it is distributed via software bundles. Following infiltration, it makes changes to browser configuration, creates a new entry in Profiles, and appends an extension to Safari, Google Chrome, or web browsers. All this is done in order to complicate the task for those who want to get rid of it. Meanwhile, users’ browsers are filled with questionable content in the form of pop-ups, banners, video/audio ads, in-text links and so on. A single click is enough for a device to end up on scam or malware-laden websites. And if that’s not enough, SystemNotes also can “read sensitive information from web pages, including passwords, phone numbers, and credit cards”, which is described in the description. Therefore, there is a high risk of confidential information leakage or even stealing money from your credit cards. To prevent these dangers, we strongly advise you not to use the browser until you remove SystemNotes Extension from your Mac.
