    Here's the deal:
    I have a Windows XP PC connected to a hub and DSL (with 2 other PCs).
    The PC in question has McAfee firewall and Virus software.
    A worm got in. It was deleted but it came back (several times).
    I set the firewall to Filter All. There's no worm BUT...
    Now nothing can access the Internet and the network settings were lost.
    I set up some new TCPIP settings (can't say if they were the original ones)
    Allowing all trafic through the firewall did nothing to solve the problem so I suspect the issue is not with the firewall.
    I can use the command window to ping other sites.

    Help please!

    Can you can both by name and IP?

    What happen if you enter in IE address bar? Are you able to access yahoo?

    If you able to ping by name and address, and entering in IE allows you to access yahoo, then you can try to delite the winsock and winsock2 keys from the registry HKLM\System\CurrentControlSet\Services as follow:

    1) Backup the registy
    2) Disable antivirus and firewall
    3) Delete the winsock keys
    4) Uninstall TCP/IP
    5) Reboot
    6) Reinstall TCP/IP
    7) test IE

    With XP, how to you uninstall and reinstall TCP/IP?

    I like to use PING rather than IE for testing Internet access. The reason is that IE can be misconfigured as well as TCP/IP. Then you won' t know where the problem is. Once you can ping by name, then you can start trying to use IE.

    1. Ping an external site by IP. If that works then you have Internet access.
    2. Ping an external site by Name. If that doesn't work, then you have a DNS issue.
