Ultimate Popup Killer Removal Guide

Do you know what Ultimate Popup Killer is?

Ultimate Popup Killer might look like a useful application if you are looking for a way to deal with annoying pop-up advertisements you may encounter while visiting various web pages. However, our researchers recently determined that together with it the user could also receive a browser hijacker called Searchby.net. Since the program’s creators claim the product is not bundled with additional software, the fact it might travel with the mentioned browser hijacker just does not make it seem trustworthy. In fact, because of the mentioned behavior, our researchers classified Ultimate Popup Killer as a potentially unwanted program. Naturally, we do not recommend keeping the suspicious tool on the computer, and accordingly, we advise deleting it with the removal guide added below the article or a reputable antimalware tool of your choice.

To begin with, the software is supposed to work only on Internet Explorer. After being installed, it allows Searchby.net hijack user’s browser by replacing default homepage. Ultimate Popup Killer can be downloaded from its website called ultimatepopupkiller.com, where you can find descriptions and other information about it as well.

First of all the web page puts a lot of emphasis on the fact the tool is free of charge. More than that the potentially unwanted program’s creators claim it is the best pop-up killer there is as according to them “there are SERIOUS PROBLEMS with” many similar applications. It also accuses other tools of being extremely expensive. It is difficult to say what specific tools they are referring to, but so far the ad blocking applications we have encountered were all free of charge. Thus, our researchers suspect the provided list describing similar software issues could be quite exaggerated to make Ultimate Popup Killer look better.Ultimate Popup Killer Removal GuideUltimate Popup Killer screenshot

Furthermore, there was one other sentence on the potentially unwanted program’s website that raised our suspicion. To be more precise, even though it says you might receive Searchby.net together with the application, one of the last sentences on the software’s homepage says “there is no additional software bundled with it.” It makes us wonder whether the other statements, such as “The Ultimate Popup Killer contains no spyware” or “does not track what you do” are true. Even if Ultimate Popup Killer does not track users itself, there are no guarantees the mentioned search engine will not act this way either. Therefore, if you are planning on surfing the Internet with Searchby.net, we would recommend learning more about what data it might collect and decide for yourself if using it is safer than browsing with reputable search engines like Google, Bing, etc.

All things considered, Ultimate Popup Killer looks quite suspicious because of its exaggerated description and unreliable since it may travel with a browser hijacker. It seems to us there are safer and more trustworthy ad blockers to choose from, so we would not recommend taking any chances with this potentially unwanted program or the hijacker it may place on your Internet Explorer. If you have made up your mind to delete this questionable tool, you could do so manually while completing the steps provided by the removal guide located below the article. Another option is to install an antimalware tool, do a system check-up, and get rid of the program along with other possible detections.
