I think it is a BUG in 12.1.2272(NITRO Update).I am now using AIS and my all shields are well activated but avast! point out “Enabled all shields(1 Disable)”,when i click on it it do nothing.Can avast! fix this issue quickly.Repair option tried but nothing help.
Well i know it will resolved by clean install,but i want to know more about the actual problem what can caused it? so i wait for avast! dev. it is very rare issue.
