Chrome Extension causing DCs

Riot, I have ticket in I appeared to fix on my own. I had to go in and turn off my Norton Security extension on Google Chrome which I found active. Normally I turned it off but it was active. Once I did this all my Disconnects stopped immediately. I didn't know one had to do with the other. Not sure how this caused the disconnects. Maybe due to the screen changes during champ select etc possibly. Something maybe to look at
