Your log(s) show that you are using so called peer-to-peer or file-sharing programs (in your case qBittorrent). These programs allow to share files between users as the name(s) suggest. In today's world the cyber crime has come to an enormous dimension and any means is used to infect personal computers to make use of their stored data or machine power for further propagation of the malware files. A popular means is the use of file-sharing tools as a tremendous amount of prospective victims can be reached through it.
It is therefore possible to be infected by downloading manipulated files via peer-to-peer tools and thus suggested to be used with intense care. Some further readings on this subject, along the included links, are as follows: "File-Sharing, otherwise known as Peer To Peer" and "Risks of File-Sharing Technology."
It is also important to note that sharing entertainment files and proprietary software infringes the copyright laws in many countries over the world and you are putting yourself at risk of being indicted through organisations watching over the rights of the authors of such files (i.e. the RIAA for music files, or the MPAA for movie files in the USA) or the authors of the files themselves.
Naturally there are also legal ways to use these services, such as downloading Linux distributions or office suites such as "Libre Office or GIMP."
