Bitdefender Downloaded Multiple Plugins And My Laptop Went Beserk. Have I Been Compromised?

Can someone tell me what the F is going on? Bitdefender downloaded multiple plugins and then my laptop went beserk - opened files, browsers, etc, and I lost control of the mouse. I rebooted and I have control again, but I'm afraid to open anything important. What is going on? Have I been compromised???
