I have a customer who has an Acer Laptop running Vista Home Premium who cannot bring up a any web pages using IE8, Fire Fox, or Safari. With IE he gets "Web page not found" and in Fire Fox he gets "The connection was refused" and a similar message in Safari. However he can access the internet via any other means such as IM, PING, or using Vista Update. It also does not matter whose network he uses to access the internet; i. e. his house, Starbucks, or my house. It also does not matter if he uses wired or wireless connections. Therefore it's not his home network hardware. I cannot find anything that appears to be a virus or malware. Any ideas?
