After updating BitTorrent's uTorrent, some users reported that mining software had appeared on their PCs without their consent

Some people who use uTorrent, the popular BitTorrent client, are up in arms over the presence of cryptocurrency mining software on their computers which they say was installed without their permission.

The mining software, made by the company Epic Scale, started appearing for some people earlier this week after they updated to the latest version of uTorrent, a program made by BitTorrent for downloading files. In forums online, users have likened the software to bloatware, as it taxes their computer processor without their consent. Cryptocurrency mining software is used to release bitcoins and other digital currencies by having computers persistently perform complex mathematical calculations.

Some uTorrent users have said their computers were slowing down and overheating due to the software, kicking their fans into overdrive. Others reported persistent pop-ups they couldn't remove, or messages saying their computers were unable to connect to a server.

"When I arrived home this evening my PC was running at full tilt and practically blowing steam," one user wrote on the site for FreeFixer, which makes a tool for removing unwanted software. A thread there has amassed dozens of complaints over the past couple of days.

Users said they received no notification that the software was being installed.

"The only reason I found out about it was that I was playing a game and it was running much slower than usual with constant hiccups," one user wrote.

Users have reported similar complaints in a forum on uTorrent's own site, according to news reports, but those threads have since been removed.

A spokesman for uTorrent maker BitTorrent said there is no silent install happening. Epic Scale is one of many partners that BitTorrent has that might provide installation offers during the install of uTorrent, and the installation is optional, BitTorrent said in a joint blog post with Epic Scale on Friday.

Still, BitTorrent is looking into the issue internally and with Epic Scale, BitTorrent said in the post. The company has received less than a dozen inquiries about the issue over the past 24 hours, the spokesman said.
