For the past two days, Avast will suddenly say "You are un protected" and then either turn itself back on, or will do it when I click it. However every time it does this it stops my full system scan before it can scan full system and I fear this will cause it to not catch a virus. How to fix this? Also two of the five times this has happened a thing came up saying something wanted to turn avast off if I agreed to let it (it had an automatic timer that avast would say no for me thankfully.)
