It is disguised malware installer. It appears on sites where the use thinks they are downloading a 'torrent.' It may download a torrent but it also installs this malware.

The file was used for BitDefender's Anti-Virus 2013 updating process. No threats found.

It is often a mandatory download if you get to ' immediate download' sites. It seems highly dangerous to me to download and activate an exe file from peopel you dont know, purely so you can download other files
The Bitdefender antivirus update executable. In C:\Program Files\Bitdefender\Bitdefender 2013
It came to me from the Softonic downloadsite. I don't like to instal software in order to download a file.

Best practices for resolving downloader issues

A clean and tidy computer is the key requirement for avoiding problems with downloader. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the downloader.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
