Chrome.exe runs on its own and drains my processor power

I see like 15-20 chrome.exe processes in task manager and yes I know chrome uses several processes to separate workload. But the worst part is, I din't even oppened Chrome and yet I see those 20 processes, and in the last few weeks or so, one or two of those processes run on at least 30-50% CPU power which makes my cooler work harder. I even think chrome is doing something with my Inteet coection as I caot play multiplayer MOBA game without unbearable lags.

As if I have some virus, but not sure, I scaed with Spybot S&D and it found only regular things it finds each time I scan.

Should I remove Chrome or what should I do, any suggestions?

Note: There is not Service in Windows Services Management. And also In Chrome process list when I open in Tools-> Task Manager I see only few processes.

By the way it is Windows 7
