Unknown Program Running On The Background Of Computer

I have some sort of program running on the background of my computer that seems to be disturbing any kind of task I try to accomplish on my cpu. It seems to be running every 30 seconds or so for a brief moment and then repeats over and over again. Whenever I try to type, this program or virus clicks off the current window, in which I have to reposition my cursor again back to where it was originally. Even as I type now, I am having to click back onto this editor every 6 or 7 words. I have checked my task manager and cannot find any processes that are running since the only happens and causes a disruption for a brief second. This is very odd and seems to make any task that much more aggravating.
