CPU miner malware?

Apparently, somehow, someone installed a cpu mining program on my computer that only works when the computer is idle. If not for the cpu desktop widget, I wouldn't have noticed it!

Here's the configuration file, in case we can stop this upstream on bases of fraud:

C:\Users\Avi\AppData\Roaming\cpuminer: cpm.exe cpuminer-conf.json cpuminer-uninst.exe msvcr120.dll

Conf reads, but poolminer.net doesn't resolve.

{ "api-bind" : "0",

"url": "stratum+tcp://pool22.poolminers.net:2844", "user" : "miner", "pass" : "X",

"algo" : "cryptonight",

"on-idle" : 30, "on-idle-low" : 30,

"background" : true, "quiet" : true }
