avast! Chrome plugin not installed... But it is? O.o

Hello :smiley:
avast! Keeps coming up with a popup every time I start my PC. It says that I should install the Google Chrome avast! WebRep plugin; and then there’s a little blue button that says “Install”.
I clicked it and it redirected me to an avast! website. But then at the bottom, it says I already have it installed. I look on the top right of my Google Chrome screen and see that it is installed. So why does that popup display every time I start my PC? I mean it’s not really annoying or anything. And sometimes it doesn’t popup. Not a huge deal. But I just want to know why :stuck_out_tongue:
Thank you for reading! :smiley:
