One or more of the identified infections is a backdoor trojan.
This allows hackers to remotely control your computer, steal critical system information
and download and execute files
I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.
Though the trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?When Should I Format, How Should I Reinstall
We can still clean this machine but I can't guarantee that it will be 100% secure afterwards. Let me know what you decide to do.2.
Your log(s) show that you are using so called peer-to-peer
programmes (in your case BitTorrent
). These programmes 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 "Open Office."3.
