Hi Frank,
Did you check the proxy server settings in IE and Firefox? Some viruses
run a local proxy server and change the browser settings to point to
it. While the virus/malware is running, the browser may work normally
for the most part although the proxy might inject ads, pop-ups or
collect information about the sites being visited. Once the virus is
removed, the browser can't access any sites because it is pointing to a
nonexistent proxy server.
