If you find yourself in a browser extension called TopSites Tab whenever you open a new tab, then you might have a potentially unwanted program (PUP) or an adware in your system. What is TopSites Tab? TopSites Tab is browser extension which, according to our researchers, is classified as a potentially unwanted program. Though it is advertised as a tool that you must have in your computer to improve your computer’s browsing experience and performance. However, that is not the case since after a detailed test and analysis; researchers found that this browser extension makes unwanted changes on your computer’s settings without notifying you or without any authorization. So unlike what it claimed, it does not improve your browsing experience at all and makes it annoying and frustrating instead.
This browser hijacker denotes potentially unwanted program behavior since it aggressively modifies the configuration of your web browser. It changes the settings of the corresponding shortcuts so that the unknowing user keeps on visiting the wrong site whenever they open browsers like Google Chrome, Mozilla Firefox, Internet Explorer and other browsers.  It modifies the original target value of shortcuts with the deceptive URL resulting to a new action triggered whenever you open the shortcuts.

Moreover, the Topsites Tab has the ability to add new intrusive extension to your browsers. The main purpose of this browser hijacker is to inject sponsored items such as banners, graphical comparison shopping sections, in-text links, pop-ups and ads into the content of the websites you visit. All of these annoying sponsored items will cram up your regular web pages and tend to slow down the website’s loading time. The browser hijacker can also monitor the user’s web browsing activities in order to know what to ads to display according to the users preference since it can spy on your search queries, what websites you visit often and your login details such as your email address.
What makes the TopSites Tab unique is that it operates without the help of any separate application on a computer system and achieves the appending of shortcuts by executing a specific VBScript command. And that is not a characteristic of your usual potentially unwanted program or adware. That’s why some anti malware programs may detect the appended shortcuts but will not detect the actual perpetrating code responsible for appending the shortcuts which is really complicated to troubleshoot without the help of a trusted and reputable anti malware program like SpyRemover Pro.
Another reason why TopSites Tab is categorized as a potentially unwanted program (PUP) is that it is distributed suspiciously. Even though it can be obtained through its official website and the Google Chrome store, it does not mean that it is a safe and trusted application. Why? Because researchers have found that this program is also distributed through bundled packages of software. Software bundling is usually the distribution method cyber criminals use to spread malicious application like Ransomware, Trojan and other viruses. Thus, it is highly recommended to check every software you download online especially if it came through a bundle from a free sharing website.
