I’ve been having this problem for some time now with a number of versions of Avast. With Avast running, the wifi indicator on my Windows 7 toolbar will show an error that it has “No Internet Access” even though it actually does have access and I can surf the web fine. If I temporarily turn off the shields and refresh the connection, the error message will disappear and I can reactivate the shields. I have tried the suggestion I found elsewhere to have Avast load after other services but this didn’t help. Any suggestions?
