Since a weeks ago a cmd.exe has been running in the background, it doesnt always starts in all the day but when it does a quick cmd window pop up and then dissapear, I can confirm that it is still running because I check the task manager.
I dont know if is a virus or just a software that I installed because mbam daily scans my pc and it doesnt found any threat, I got the premium version, I can add that I can close the cmd from the task manager but it will start again in a few hours, also sometimes it close for itself.
Sorry for bad english, here are some reports:
