When I am not using the computer, the screen eventually changes to sleep mode. Then I touch the keyboard, the screen prompt out the logging etc; I notice the icons of the avast and others disappear from the bottom of the Windows operating system .They reappears like usual start-up or rebooting.
My computer is a wireless laptop and I do not switch off and disconnect the internet modem when I am away. I worry if the aVast works when the computer is sleeping or it sleeps as well.
