The Ultimate Popup Killer is a browser add-on, which is described as one-of-a-kind way to stop pop-ups from bothering you while you browse the Web. The official download page of the extension states that it is unlike other software of this sort, because it does not block important pop-ups provided by legitimate websites, and it barely uses any system resources, therefore, minimizing the impact it has on the computer's performance. While we can't either confirm or deny these statements, we can say that the Ultimate Popup Killer's installation may lead to unwanted changes to your browser's configuration.

The 'Frequently Asked Questions' on the Ultimate Popup Killer's website reveals that users who opt to install this software will have their default Web browser's homepage set to Searchby.net. The peculiar thing is that this change is irreversible since the Ultimate Popup Killer will continue to apply this change as soon as it starts. There are only two workarounds – either remove the Ultimate Popup Killer or purchase the 'premium' version for $12. Needless to say, you should not agree to spend money on ad-blocking or pop-up blocking software when there are countless free alternatives that will not force you to use a 3rd-party website whenever you launch your Web browser.

If you have installed the Ultimate Popup Killer and you would like to stop using it and restore your Web browser's homepage, then we advise you to consider the Ultimate Popup Killer's removal. It should be possible to remove this software manually, but if you want to fully ensure its removal, then you should use a suitable PC security scanner that can deal with Potentially Unwanted Programs.
