When avast update the virus definitions it shows up the green notification pop up and that's ok. The strange thing is that the voice repeats two times the same sentence "the virus definitions database of avast has been updated". Two days ago all was normal, avast showed the pop up and the voice said this sentence only one time, as it should be. Why now my avast repeat this vocal message two times? It says this vocal message one time,before the green pop up appears, and then another time, when the green pop up shows up. What's the problem?
