Every time I load a new Web page in Safari, there’s an annoying square icon that appears in the upper left corner, with the Avast logo on it. Anyone know why, and how to get rid of it? I have “Web Shield” off, so there shouldn’t be anything going on in the browser.
This wouldn’t be acceptable even if “Web Shield” were on…
You installed avast so hence you gave permission for that feature to be installed, if you had chosen the custom install then you would have been given the opportunity to deselect the features you don’t want or need.
Not sure if the Mac uninstall method is the same as for windows but if you click to uninstall in windows you are given another screen where you choose “change” and the following screen will allow you to deselect unwanted features.
