QuoteuTorrent's latest update may be hijacking computers to turn a profit. According to a report from Trusted Reviews, the latest update to the popular torrent management software comes bundled with a program called EpicScale, which uses the computer's processor to mine bitcoin in the background. Since the program is installed automatically as part of the update process, most users were unaware that their computers were being used to mine bitcoin, and only discovered the program was running after noticing the significant increase in processor load. In a forum thread, a uTorrent representative confirmed the bundling, saying, "Epic Scale is a great partner for us to continue to generate revenue for the company."

I guess I'm okay with this.
Been using Deluge for 8 months, now.
