Avast Internet security renew issue

I used free antivirus for many years. Now I got plenty of different things, that I never new about. Grime fighter, browser cleanup and so on. I bought grime figter - good, then avast offered me internet security for free for mounth, I agreed. Now, avery time I boot in my windows in shouts, that I am unprotected. Can something be done about it? Without purcasing it.
