Solution 2: Add an Exception in Avast

Steam and Avast simply don’t get along well. Avast is even in Steam’s list of programs that interfere with the Steam installation and it’s clear to see why. The real cause of this problem is probably the fact that the Steam client has been flagged by Avast! The only way to resolve this problem and keep both apps installed is to add an exception for it by following the steps presented below!
