Type: Potentially Unwanted Application


How do you find file converters online? You might think that apps like PDFConverterSearchTool are there to assist you. In reality, this extension was not designed to help you with converter searches per se. It presents a search tool, but that is pretty much it. You can use it like any other search tool, which means that you can find anything using it, perhaps even converters. That said, we do not believe that this tool is reliable at all, and we strongly recommend deleting it from your Google Chrome browser. At the time of research, this was the only browser that the PUP (potentially unwanted program) was compatible with. If you have yet to understand the extension fully, we strongly recommend that you continue reading our report. If you end up deciding that you do want to remove PDFConverterSearchTool as per our recommendations, we discuss a few different options too.

When we analyzed PDFConverterSearchTool, it could be downloaded from and The first website appears to be an official source, but the creator of the PUP must have placed the installer on the Chrome Web Store as well, and so this source could too be regarded as an official one. If you have used neither of them, perhaps you found the extension introduced by a third-party installer. Perhaps you installed it along with other extensions and programs. Unfortunately, PUPs are often spread with even more suspicious pieces of software, and if that happens, you might have to deal with the removal of multiple threats. The same can be said about VideosSearches, ConverterSearchTool, PDFConvertersSearch, and other extensions that come from the same family as PDFConverterSearchTool. So, if you have any of these installed on your browser, we strongly advise installing a malware scanner. If this scanner is reliable, it will warn you if there are any threats that require removal.

PDFConverterSearchTool has more similarities with the extensions from its family than differences. One of the most important things is that these extensions always hijack the default search provider on Chrome, and it is always hijacked in the same way. is the tool that is introduced by the PUP discussed in this report, but it acts just the same as or They all redirect searches to, and this is not good news. Isn’t Yahoo Search a reliable and well-respected search engine? Perhaps it is, but not when PUPs are redirecting to it. As it turns out, the search tool introduced by PDFConverterSearchTool modifies these results, and that means that you cannot trust the service. Unfortunately, some users might not realize that anything is out of the ordinary, and they might end up clicking unreliable links. Would every one of them be unreliable? We cannot know for sure, but that is a possibility.

In conclusion, we strongly recommend that you delete PDFConverterSearchTool from your browser because this extension cannot offer you anything useful. Even though it presents Yahoo Search results, they could be modified, and it is possible that quite unreliable links could be injected. Obviously, this is not a good way to “optimize” search results. Of course, that should not deter you from using Yahoo Search if that is the search tool of your choice. Simply make sure that no program or extension is redirecting you to this engine and modifying the shown results. When it comes to the removal of PDFConverterSearchTool, there are a few options to choose from. You can eliminate this PUP manually, and the guide below explains how to. That said, if you are going with this option, you must scan your system beforehand to check if any other threats exist. If they do, you must delete them also. On the other hand, if you decide to implement anti-malware software, you will not need to worry about any of this. Threats and PUPs will be deleted automatically.
