Q: my screen is flickering. Is it a virus?

Hi.

 

I have recently come across this issue.

My iMac screen started to flicker intensely and then crashed. I was looking at a site on Chrome and this flickering started to appear.  Could it be a virus/malware. I didn't download anything. I've restarted the computer and immediately the problem occurred.

 

I started it in safe more and it works better but still there is a little flicker when animation needs to happen within the window (EG finder, chrome browser, not that much in firefox, notepad and more.)

 

I've uploaded a video to Youtube to show you what I am talking about : http://youtu.be/VWRZzMhFE94
