It was only a matter of time:
When I updated uTorrent to version 3.4.2 build 28913 (32-bit) this morning it silently installed a piece of software called EpicScale. There was no information about this during installation and I did opt out of your other bundled software.
EpicScale is a bitcoin miner that also purports to use your “unused processing power to change the world”. It’s easily noticeable by the increased CPU load when the computer is idle.
