It might come as a surprise, but RinoReader is regarded as a potentially unwanted program that you might want to remove. To our knowledge the application works rather well, but we would not go so far as to say that it is on par with other, more well-known PDF readers, such as Sumatra PDF, Foxit, Adobe Reader, and PDF-Xchange. Research has shown that RinoReader might silently install a Trojan called Trojan.downloader.Adcurl. It goes without saying that a Trojan infection will cause you problems. So we suggest that you remove RinoReader.
RinoReader is advertised as a lightweight application that opens PDF documents. The application is advertised on a website called Rinoreader.com. The website does have a download button, but at the time of this article the application refused to install. We think that the installation executable is corrupted, since it is only 0 kb in size. However, if you manage to install the application from other sources, let us know where you got it in the comment section below. If the installation is successful, the program will install 4 files in total. One of them is called pdfium.dll, which is a Foxit PDF SDK DLL. Another one is called PdfiumViewer.dll made by Pieter van Ginkel. Our analysis has determined that these files are non-malicious, and thus safe.
As far as RinoReader’s distribution is concerned, it is primarily downloaded and installed in the United States with a share of 51.79% of total worldwide downloads. The other two countries where RinoReader is popular are the United Kingdom with 19.64% and France with 10.71%. We suggest that you remove RinoReader, since there are better alternatives for this unreliable application. In any case, let us discuss the most important issue in this article.
As mentioned, if you install RinoReader, it is likely that you will get Trojan.Downloader.Adcurl as well. The Trojan poses a medium risk to your system’s security, but still, we think that you should remove it as soon as possible. The Trojan works as a Windows process and is known to have different names. We have managed to get a few known examples. If you want to check whether your computer has been infected by Trojan.Downloader.Adcurl, go to the Task Manager and look for processes called notify.exe, hbx.exe, iyg.exe, or setup.exe. Of course, in the case of setup.exe, you might want to check if you are installing something before you come to the conclusion that your computer has been infected. The Trojan is surely malicious, since it can download additional malware and jeopardize your computer’s security. So it is highly recommended that you remove Trojan.Downloader.Adcurl.
RinoReader is not a malicious application. It performs the function for which it is advertised. But, since it might download Trojan.Downloader.Adcurl, it is unreliable, so you might want to remove it. Uninstalling RinoReader is not a difficult process, but we have prepared a manual removal guide just in case. The Trojan, however, cannot be uninstalled via the Control Panel, so you will have to get an antimalware scanner to remove it.
