I am using a MacBook Air 13' bought in 2017, running Mojave 10.14.1 (18B75). I recently removed malware and plugins named Weknow.ac. Now, several of the application badges and indicators in the menu bar appear with a blue background. I've tried different things to remove the background color, mainly by upgrading and re-installing the apps affected, but nothing seems to work. Any help would be much appreciated.
