BestPDFSearch

Do you think that a free extension called BestPDFSearch can offer you “best” of anything? If you do, you might be disappointed to learn that it is useless. We identify it as a potentially unwanted program (PUP), and we are sure that most users are better off deleting it from their Google Chrome browsers. That being said, some might also find it beneficial. The problem with tools, programs, and add-ons that offer something at least remotely useful is that their users often turn a blind eye to the more suspicious things. We do not identify the extension as a PUP because it seems to offer no useful service only. We also put it in this category because we believe that there is some level of threat that every user could face while interacting with it. If you want to remove BestPDFSearch already, we can support you in the process. The good news is that it is pretty straightforward, and not many steps need to be taken. However, things can always change, and how you install the PUP could factor in.

Are you familiar with the Chrome Web Store? If you use Google Chrome, it is likely that you are. This is the app store that offers the biggest variety of extensions, and it is also the most trustworthy store for Chrome users. Nonetheless, PUPs can be found on it too, and BestPDFSearch can be found at chrome.google.com/webstore/detail/bestpdfsearch/ogbogblfllonoloohickhaibcgkpheck. At the top of the page, you can find that the extension is “Offered by” bestpdfsearch.com, but if you click the link, you are routed to portal.bestpdfsearch.com. This page does not offer an installer, and so it seems that the Chrome Web Store is the only relatively trusted source for the PUP. We are not surprised that this is how the extension is presented because that is exactly how SportsHDSearchs, ConverterzSearch, SearchProConverter, and other extensions identical to BestPDFSearch are presented also. Of course, they could also be introduced via bundled downloaders or unreliable installers, and they could enter systems along with other suspicious extensions or applications. If you want to know if there is anything that you should delete from your system, we advise implementing a malware scanner.

According to our research team, BestPDFSearch has the power to change the New Tab page and also the default search provider on your Google Chrome browser. Portal.bestpdfsearch.com is likely to take over the New Tab, and feed.bestpdfsearch.com should be set as your normal search provider. The portal page can seem useful because it can help you convert files and currency, as well as use a calculator. However, the main attraction is the search dialog box, and if you enter keywords into it – or use the address bar to search with the default search provider – you will be redirected to Yahoo Search. Why would a tool that is supposed to help you search for PDF (judging by the name) redirect to this engine? That is because it can be modified easily, and that allows the creator behind BestPDFSearch to expose users to sponsored links. Who is behind these links? We do not know, but we know that your browsing history could be used to personalize the service. Unfortunately, the PUP is simply too unpredictable, and the supporting privacy policy does not offer enough information, which is why we do not recommend trusting it.

The removal of the PUP should pose no problems. Open the Extensions menu on your browser, find BestPDFSearch, and delete it. Obviously, if you are new to such practice, you might lack confidence, and that is why we have created a guide. This guide can help you delete BestPDFSearch and also clear browsing data. We suggest picking the time range in which the PUP was installed and clearing everything because you do not want any traces of it left behind. Follow the guide to figure that out. If you do not have time for manual removal, if other threats exist, or if you are looking for ways to strengthen your system’s defenses against PUPs and malware, we suggest anti-malware software. Install it, and it will solve these issues instantly. Needless to say, even if you have your system secured, being cautious when installing extensions and programs in the future is crucial.
