Hello. I've just updated to Avast 7.0.1426 and the web shield won't work. It is shown as Off and when I try to turn it on, nothing happens. When I go to its tab in Avast interface, i see the message Protection status: Service stopped. from services.msc though is obvious Avast's service is running, besides, all other shields are working. My system is running WindowsXP SP3, all later updates. Any ideas?
