Specialists at 411-spyware.com have recently informed us about the detection of a new potentially unwanted application – Sumnum. It is a PUP in the form of a Google Chrome browser extension, so only those users whose default browser is Google Chrome will encounter it. Some of them download and install this extension willingly from the web, whereas others cannot explain why this piece of software has appeared in the list of extensions. At the time of writing, it seems that Sumnum is only distributed using deceptive distribution methods and enters users’ PCs without their knowledge because it is no longer possible to get it from its official website – the extension has been removed from the Chrome Web store and, consequently, the Add to Chrome button on its official website http://yearlia.com/yearliator12?utm_source=zeropark is no longer active. Of course, you should remove Sumnum from your Google Chrome browser no matter what is the story behind the installation of this piece of software. You cannot keep it because it is not a trustworthy application that is going to act beneficially on your computer. As research conducted by our experts has shown, it is nothing more than a potentially unwanted program (PUP) which acts in an undesirable way.
Sumnum has an official website http://yearlia.com/yearliator12?utm_source=zeropark, as has been already mentioned at the beginning of this article. Even though it is no longer possible to download it from there, we are sure that there are users out there who willingly downloaded this piece of software from its official website some time ago. Users usually do not come across this URL accidentally. Instead, they are usually redirected to it against their will from another untrustworthy domain. Since it has already been removed from the Chrome Web store and cannot be downloaded from its official website, it is very likely that the majority of users install it on their PCs by clicking on a pop-up promoting it at present. These pop-ups can be found on untrustworthy pages, or they might keep appearing on your screen because an adware program is actively working on your system. In the latter case, you must delete adware from your computer too.
Follow our instructions you can find below this article to remove this undesirable Google Chrome extension from your computer. It is not dangerous malware, so you should not find its deletion very complicated. If it is exactly what you think about the manual method, delete this PUP without mercy with an automated scanner.
