Search.sonicpdfconverter.com looks like a normal search engine that has some useful links built into its interface. However, it does not have a good reputation because of the way it is introduced to users, because of its ability to record personal information, and because it can reroute to a third-party search engine without permission and show sponsored content via it. In a nutshell, these are the main reasons for deleting Search.sonicpdfconverter.com from your browser. According to our research, Mozilla Firefox, Google Chrome, and Internet Explorer browsers can be affected by this hijacker. Surprisingly, in most cases, users let it in themselves. Have you let in the infection knowingly? It is more likely that you saw no other choice or you installed it by accident. At the time of research, an official installer did not exist (sonicpdfconverter.com/FileConverter? does not offer an installer), which suggests that it might have been downloaded via a software bundle. Was it? If it was, the chances are that you need to remove a bunch of other infections as well.
The main feature of Search.sonicpdfconverter.com is the search tool, and it works in the exact same way as the search tools represented via Searchvzcc.com, Search.searchbrs.com, and other hijackers that were created by the infamous Polarity Technologies Ltd. As you enter keywords into the box allocated for searches, you are automatically redirected to Yahoo Search, and that is the first offense because that is done without your permission. Of course, because it is Yahoo Search, most users ignore that. The hijacker redirects the searches but adds sponsored content. That means that even though you are introduced to search results via search.yahoo.com, in reality, some links are curated by Search.sonicpdfconverter.com itself. Needless to say, that is the second offense. Unfortunately, the advertisers associated with the hijacker might be malicious, and the content that is shown could be misleading. Due to this, you should limit your interaction with it. Better yet, you should not interact with the search tool at all. Although the easy-access links represented via the interface of the hijacker are harmless (e.g., google.com or amazon.com), we do not recommend interacting with them either because your activity is recorded.
Have you encountered Search.sonicpdfconverter.com along with Sonic PDF Converter? If that is the case, you might be able to get rid of the hijacker by removing the extension. We suggest eliminating all pieces of software that might have entered your operating system along with the hijacker, and if you have a hard time identifying threats, use an authentic malware scanner. You might discover threats that you cannot eliminate manually. Even if that is not the case, employing anti-malware software is a smart move. First and foremost, it is irreplaceable when it comes to the removal of active infections. Secondly, only reliable and up-to-date anti-malware software can prevent infections from slithering into your PC in the future, and so it is worth investing in. If you remove Search.sonicpdfconverter.com manually, do not forget that reliable security software can save you a lot of trouble.
