I have two computers running Windows 7 on a wired network. Both are protected by Zone Alarm. While on the internet yesterday, a window popped up informing me that Zone Alarm had detected a virus and had taken care of it. However, afterward I could not access the internet on that computer. The second computer and all other devices work fine. I also get the message:Windows can't communicate with the device or resource (primary DNS server) I have gone through the procedures Microsoft has suggested with no success. Any ideas?
