The Smilebox Tab describes itself as a convenient application that will allow users to quickly access their favorite websites, including social media platforms, shopping platforms, etc. Another of its features is to provide users with ecards for a wide variety of occasions. However, while users are likely to immediately notice these main features, they may fail to realize that the Smilebox Tab also will change several browser settings. Indeed, the browser extension will modify the new tab and default search settings. When surprised by the sudden unwanted behavior of their browser, many users could come to the conclusion that Smilebox Tab is another PUP (Potentially Unwanted Program).

PUPs are invasive applications that carry various, unwanted capabilities and are typically distributed via questionable methods, like software bundles and fake installers. They can be responsible for the appearance of untrustworthy advertisements or cause browser redirects to unfamiliar and sometimes unsafe websites. The advertisements or redirects could take users to dubious websites, suspicious adult pages, untrustworthy online betting/gaming platforms, phishing tactics, technical support schemes, etc.

Another common issue with PUPs is that these applications may be equipped with data-tracking functions. Users could have their browsing activities monitored, packaged, and exfiltrated to a server under the control of the specific PUP's operators. The collected information often includes device details, as well - as IP address, geolocation, device type, browser type, etc.
