Avast Premium

I tried to Upgrade My Settings thru Com.Avast.cmd but my password did not work. My regular Avast password works, do I need another password? I’m also getting a pop up regarding “Avast Cleanup” would like to access data from other apps - Don’t Allow or Allow. This is part of the above password for .cmd not working. All of this occurred after upgrading to Sequoia 15.3.1
Please assist, thanks Craig K
