I am unable to browse the internet using either Firefox or IE7. I am able to connect to livemail, windows messenger, yahoo messenger. I am also able to ping websites using their domain name. Have checked proxy server settings, disabled addons, flushed dns (ipconfig /flushdns). Scans with AVG free version8 (with updates current) have been completed and have shown no infections.
Interestingly enough, if I boot into safemode with networking enabled, I am able to browse without any problems.
