Port Scan Blocked

Hello, I was watching the video from facebook in 500k profile when Bitdefender show me notification that he blocked Port Scan

Remote IP: 94.xxx.xxx.xxx
Protocol: TCP


Im afraid, Im using Bitdefender 2015, zemana, malwarebytes antiexploit free, hitmanpro alert and some on-demand scanners which I use everyday to scan.

Please tell me what I should do now ? This is normal ? in past one year of using bitdefender, such an alert never pop up and Im in little panic...
