Not really sure what to do about it. Seems to have just started happening today, it mainly pops up whilst browsing the web, mainly twitch.tv. If I go into more info, it says about 5 ports where attacked. Not sure if it's the same each time.

Seems to happen mostly when I immedially when a website page loads.. It's happened mainly on Twitch.tv but I think it happened on amazon UK also. And it seems completely random when it happens.
3rd time - Happened on YouTubes main page this time.
