New development: unfortunately I was mistaken with my post above. I disabled the plugin I believed was the source of the issue and continue to get the pop-up. I noticed that the message appears when MB tries to load the Artist Picture. After the popup, artist pictures do not load.
I backed up my AppData folder for MB, then uninstalled and reinstalled directly from the download page
. I also disabled the auto retrieval of lyrics in the Preferences as you suggested Steven.
However, I am still getting the same MalwareBytes popup every time I launch MB. I also ran a full system scan in MalwareBytes, which came back clean, and a BitDefender system scan, also clean.
Would it be helpful if I did a screen recording of the behavior?
