So basically I only installed the behavior shield from the avast installation wizard. I was thinking having Kaspersky as my main AV along with avast's behavior blocker is a good set up. However, admittingly I am a novice, and I don't know if these two will clash. So far, everything seems to be going smoothly, but the WD notification icon is displaying that X and is saying I shouldn't have more than one AV installed. Thanks.
