AVG Online Shield Service eating up CPU

I installed AVG 2016 FREE few days ago. Since Saturday, AVG Online Shield Service has been using up to 50% of my CPU. I found out this via Task Manager. I restarted my laptop (Windows 7 x64), but with no success. This CPU usage is really annoying. Anyone else got this problem?
