This is an XP system with all patches made, sitting behind a firewall using a SAMBA (ClearOS) domain controller for shared drives and NETLOGON.\r\n\r\nI was downloading a supposedly 'safe' tool from cnet and AVG jumped in to protect me. Three malwares moved to the vault. But I noticed that my shared drives were no longer available. I rebooted and no network access. Just the zeroconf IP addressing. I rebooted with a linux liveCD (Fedora 18 i386) and networking works fine, so the problem is in the XP software.\r\n\r\nNetworking properties show packets outbound, but nothing inbound; I suspect the outbound are DHCP requests.\r\n\r\nSo where do I look to get networking going again?\r\n\r\nthanks for any help. My wife is not too pleased with this computer being down and having to use another computer to access her documents.
