Astromenda

Yesterday I unintentionally downloaded Astromenda >:( into my computer. It was never listed in my program file, but other unkowns were. I deleted them. I also went to the IE and Chrome browers and changed the browser back to google. Still weird, so…I downloaded Malwarebytes and ran a skan and deleted several problems. I also ran a ful Avast skan, zip problems. But now whenever I open IE and get a window from Avast asking me if I want to open an un-named program. So I decline. Then if I’m in IE another window from what looks like Microsoft wants me to download a speller program, I decline. Chrome doesn’t look to be acting like this but I don’t usually use it. IE doesn’t want to close either. So I know I still have a problem. Does anyone know how to get rid of this? And why are these windows opening up?

I also ran a ful Avast skan, zip problems.
meaning?
