Hi Several days ago, I made the mistake of downloading and installing unknown software which I do not want. So I uninstalled it. Now i keep getting a "Command Prompt" window very quickly flashing every time I start my computer and on and off every hour. I try to scan with Malwarebytes and McAfee which have detected no problems. What is this window? How could I stop it? Please Help. got 2 print screen, says following  BITSADMIN version 3.0  BITS administration utility. <C&g
