Tampermonkey adware
Tampermonkey is a program promoted as a useful browser extension but it displays intrusive commercial content and gives no value instead.
Tampermonkey is a browser extension developed by Jan Biniok and promoted as a useful browser manager tool. However, once this intruder arrives on the system, it begins throwing various commercial content on the screen in the form of pop-up ads and coupons or commercial offers. The promotional material for this program states about the help that it provides for the everyday user, but the primary purpose of this application is to make money from advertisements it displays. Tampermonkey adware is not malicious in a way various malware[1] programs are, but you need to eliminate it from the machine so you can forget about all unwanted behavior.

Tampermonkey adware is promoted as a user script manager that is compatible with various types of browsers and offers features like the overview of running scripts and automatic updates or synchronization. However, this quickly installing browser extension can be categorized as a potentially unwanted program and adware.

This Tampermonkey virus suggests allowing access to your data and, in most cases, these details are collected and stored on remote servers for the later use of generating personalized advertisements. All this commercial content gets automatically delivered to your screen:

  • pop-unders;
  • pop-ups;
  • banners;
  • hyperlinks;
  • redirects;
  • additional browser content.

Tampermonkey tracks information about your data on websites, your browsing activity, applications, themes and usage of them. Also, most visited sites or items or even account credentials can be accessed by this intruder. When you install the program willingly, you get an additional notification about the extension and the features of data tracking that you need to allow. 

Additionally, Tampermonkey developers state about the collected information in the section of Privacy Policy on their site. The Collection of general data and information section reads the following:

The website of the company Jan Biniok collects a series of general data and information when a data subject or automated system calls up the website. This general data and information are stored in the server log files. Collected may be (1) the browser types and versions used, (2) the operating system used by the accessing system, (3) the website from which an accessing system reaches our website (so-called referrers), (4) the sub-websites, (5) the date and time of access to the Internet site, (6) an Internet protocol address (IP address), (7) the Internet service provider of the accessing system, and (8) any other similar data and information that may be used in the event of attacks on our information technology systems.

When using these general data and information, the company Jan Biniok does not draw any conclusions about the data subject. Rather, this information is needed to (1) deliver the content of our website correctly, (2) optimize the content of our website as well as its advertisement, (3) ensure the long-term viability of our information technology systems and website technology, and (4) provide law enforcement authorities with the information necessary for criminal prosecution in case of a cyber-attack. Therefore, the company Jan Biniok analyzes anonymously collected data and information statistically, with the aim of increasing the data protection and data security of our enterprise, and to ensure an optimal level of protection for the personal data we process. The anonymous data of the server log files are stored separately from all personal data provided by a data subject.

Based on these facts about the program, you should be eager to remove Tampermonkey from the system as soon as possible. This is a fairly straightforward process that involves then initial uninstallation of the program and general system cleaning using tools like Reimage.

Tampermonkey removal should be followed by a full system scan using a program that detects all possible threats and deletes them from the system. Researchers[3] advise opting for this method of virus removal, especially when dealing with potentially unwanted programs. 

Potentially unwanted software come without users' knowledge
