No i mean that i was suspecting that it could be because of some virus. But when you said that you've got NOD32, Spybot and MBAM, i guess that its not a virus. Use Snipping tool and capture a screenshot of Task manager and upload it here.
To use snipping tool, open task manager and click on Processes tab. Now click start, in the search box, type snip
and press Enter. Using your mouse, cut the taskmanager and save it.
Then click on the pin and upload it here. (See screen shot below)
