Ultimate Popup Killer is a typical potentially unwanted application even though it is advertised as a powerful pop-up blocker. If users open http://ultimatepopupkiller.com, which is its official website, they find out why this program is better than others. For example, it promises not to use too much system’s resources and, on top of that, it claims that it can block ALL pop-ups that appear on users’ screens. Yes, this application might look quite useful, but you should still not install it because more trustworthy applications that act as pop-up blockers are available, and you should definitely use one of them instead. We will not try to convince you that potentially unwanted programs are very harmful because they are not. Of course, it does not mean that these programs cannot bring any problems to you. If you cannot easily decide what to do with Ultimate Popup Killer, you should read the rest of this report. We are 99% sure that you will decide to delete it when you read this article till the end.

Ultimate Popup Killer does not act like harmful malware, but there are still several reasons why it is called an untrustworthy program and has been categorized as a potentially unwanted program. Yes, it really acts as a pop-up blocker – you will hear the gunshot sound each time it blocks a pop-up, but it has also been observed that it can change Internet Explorer settings without the users’ knowledge. Technically, it does not do that itself. Instead, it installs a browser hijacker Searchby.net on users’ computers and then it alters Internet Explorer settings right away. It will set a new page as a homepage and New Tab page. The page set might look like a legitimate search provider, but we would not use it if we were you because it might display untrustworthy third-party links and redirect you straight to corrupted pages when you click on any of them. What is more, we cannot call this program very useful because it is compatible with Internet Explorer only, meaning that pop-ups that appear to you when you use Mozilla Firefox, Google Chrome, or another web browser will not be removed from your screen. Also, it works with older versions of the Windows OS only. It is, of course, up to you whether to remove this program or not, but it should definitely be removed if you have found it completely useless or it has been installed on your computer without your knowledge.

It is no longer a secret how Ultimate Popup Killer enters users’ computers. Some people download it from its official website http://ultimatepopupkiller.com willingly and install it on their PCs. Of course, not all the users who find this potentially unwanted program installed on their computers know about its entrance, which suggests that it might enter PCs in a different way too. Specialists working at 411-spyware.com have confirmed this. Research conducted by them has clearly shown that Ultimate Popup Killer might also travel in software bundles. To put it differently, users might install it on their computers without their knowledge while installing third-party software downloaded from the web. Users download this software bundle containing the potentially unwanted program from an untrustworthy page, e.g. some kind of file-sharing website. It is not always easy to notice these additional offers and dismiss them, so we do not think that you will protect your computer all alone. What we recommend for you is installing a reputable security application.

It is not that hard to remove this pop-up blocker because it has an uninstaller. Unfortunately, the changes applied to your Internet Explorer, i.e., Searchby.net set as your homepage and New Tab will stay, meaning that you will need to fix the affected browser yourself. You can reset it to default or simply set a new URL as your homepage and New Tab page. Our instructions will help you to completely remove Ultimate Popup Killer, but if you are looking for a quicker removal method, you should use an antimalware scanner. It will remove the potentially unwanted program for you in no time and, additionally, it will fix your hijacked browser.
