The Cyber Shield is a browser extension that could display unwanted behavior. Advertised to users as a convenient tool that will help them increase the security of their data while browsing online, the application tries to mask its adware capabilities. In addition, according to cybersecurity researchers, the Cyber Shield has been observed to be distributed via deceptive websites trying to convince their visitors to install a supposedly important Chrome update. As a result, the Cyber Shield also falls in the PUP (Potentially Unwanted Program) category.

PUPs, sometimes, may possess some useful characteristics, but in most cases, their intrusive behavior far outweighs the benefits they provide. For example, adware applications could severely impact the user experience on the device they are installed on. They may frequently generate advertisements in the form of pop-ups, notifications, banners, etc. The advertisements may even start to cover the legitimate content displayed on the sites visited by users. In addition, the advertisements themselves may promote untrustworthy or questionable destinations (fake giveaways, shady adult pages and phishing scams). 

PUPs are notorious for often having data-monitoring capabilities, as well. While active, these applications may continuously track users' browsing activities and transmit the captured data to their operators. However, depending on the specific PUP, the collected information also may include device details (IP address, geolocation and device type) or information extracted from browsers' autofill data (account credentials, banking details, payment info, etc.).
