Is this entirely true? I recommended Avast to a friend who got a brand new laptop from Dell this weekend. He installed the latest version of Avast and he used Kerio as his firewall. He is not able to browse the Internet with Web Shield active. I’m going to suggest that he make sure Web shield has access through his firewall. Is that all we need to check? Does he have to worry about proxy settings at all if he’s using XP?
