I tried Avast clean up and let it do its thing. The next morning I noticed that my spell checker wasn't working anymore on sites like reddit or well typing this. What did Avast Clean Up do and how do I get my spell checker back? (Windows 10 using Internet Explorer) It was working (underlining misspelled words in red) with no problems until after I ran Avast Clean up. And yes I checked Win 10 settings spell check is on and works for Google but no other web page.
