Remove the Minerd CryptoCurrency Miner (Removal Guide)

  • March 16, 2017

The Minerd Trojan is a program that when executed will install and execute a copy of Cpuminer on the infected computer in order to mine the Monero cryptocurrency. When installed, this PUP installs a miner called minerd.exe, which is a renamed copy of the legitimate Cpuminer program.

When started, minerd.exe will mine the Monero cryptocoin by using the processing power of your computer's CPUs. While running, your computer will be added to a mining pool on xmr.pool.minergate.com using the username barinbar31@gmail.com in order to mine the Monero digital currency.

  • Minerd in Task Manager

What makes this PUP even more concerning is that this program will attempt to use your CPU all the time. This causes your computer to consume extra electricity, generate unnecessary heat, and could potentially damage your hardware due to its constant utilization. It's fine if you are choosing to use your computer to make revenue for yourself, but for another program to do it on your computer without your permission is the same thing as stealing from you.

The command that is executed to start the miner is:

minerd.exe -a cryptonight -o -o stratum+tcp://xmr.pool.minergate.com:45560 -u barinbar31@gmail.com -p x

How was Minerd Installed on My Computer?

It is important to note that Minerd is bundled with and installed by free programs that did not adequately disclose that other software would be installed along with it. Therefore, it is important that you pay close attention to license agreements and installation screens when installing anything off of the Internet. If an installation screen offers you Custom or Advanced installation options, it is a good idea to select these as they will typically disclose what other 3rd party software will also be installed. Furthermore, If the license agreement or installation screens state that they are going to install a toolbar or other unwanted adware, it is advised that you immediately cancel the install and not use the free software.

Without a doubt, Minerd is a program that uses your computer's resources for someone elses benefit. It is strongly advised that you remove this PUP and any related adware by using the removal guide below.
