    I just removed trojan viruses and now the internet will not connect either by wireless adapter or hardwired. What am I missing?

    The activity is on a desktop computer, and I am currently on a borrowed laptop.

    I've tried ipconfig, netsh, resets, and it still will not work.

    It shows that I'm connected to the network, but no internet. Internet activity meter shows 'up' kbps, but can't ping anything!

    I have a wordpad .rtf doc of all my screenshot info... Don't know how to show you.

    Malware will often change Lan settings and configure proxy settings by "tunneling" traffic through a certain port (e.g. Local address: 127.0.0.1 Port: 5555).

    Open Internet Explorer. Click Tools > Internet Options > Connections > Lan settings > Proxy server > Advanced > delete proxy server settings > click OK > uncheck all boxes > click OK.

    In Firefox, click Tools > Options... > General > Advanced > Network > Settings > delete proxy settings > select No proxy > click OK.

    Start, Run, CMD, OK to open a command prompt:
    (For Vista or 7 type CMD in the Search box after Start)

    Type the following command:

    IPCONFIG /ALL

    [Note that there is no space between the slash and ALL.]

    Right click in the command window and choose Select All, then hit Enter.
    Paste the results in a message here.

    If necessary use a text file and removable media to copy the results to a computer with internet access.

    I've done all of the cmd and reset.bat steps. I have a screenshot.rtf, but no way to upload it.

    I also just reset potential proxy setting, and there was a proxy '*.local' but I had already unchecked all the boxes including the proxy settings. The proxy is gone and checkboxes unchecked.

    Press the Windows key + R to open a Run box.

    Type services.msc

    Click OK.

    Scroll down to the DHCP Client service.

    Make sure it's Started and Automatic.

    If it is already, Stop and restart it.

    Sometimes a non-Windows security application (firewall, security suite, anti-virus, etc.) gets badly corrupted during battle. What one(s) do you have?

    Try the IPv4 stack reset (the one that got "Access is denied") in Safe Mode.

    Thank you for getting back to me, but I really need more help than that.

    I ran the reset, netsh reset and even netbios reset. Nothing is working! Somehow, there is a block to connecting to the internet.

    I just did a hard reinstall of the os and the problem persists!

    FYI, I have no programs on there now.

    Did you install your network adapter driver?

    There was already the driver for it loaded, but I reinstalled one via flash drive from marvell website.

    It will still connect to the network, but not the internet! I can't figure this out!

    I tried creating a registry file to disable ipv4 autoconfig: Start, Run, regedit:

    HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters : rt click, new DWORD (32-bit), IPAutoconfigurationEnabled, value 0

    So far, even the autoconfig doesn't change.

    I can't seem to find what exactly was changed from the virus, but the restores should have fixed it!
