We have worked for many days in the malware forum and believe that the malware is gone. We want to do a final check online, but the internet has not been working since I was infected and until I can get the internet working we cannot do the final check. The malware guy said the internet problem is not now malware related. You can see what we did as well as the latest hijack this log at http://www.geekstogo...ed-t229742.html.

Thanks in advance for your help...

Malware infection will often mess up internet connection...

Turn off computer. Disconnect router, and modem from power source for 30 seconds.
Power them back on.
Restart computer.

If that doesn't work, bypass router, and connect computer straight to the modem.

If that doesn't work...
Go Start>Run (Start search in Vista), type in:
cmd
Click OK (in Vista, while holding CTRL, and SHIFT, press Enter).

In Command Prompt window, type in following commands, and hit Enter after each one:
ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew


Restart computer.

If that doesn't work...
Go Start>Run (Start search in Vista), type in:
cmd
Click OK (in Vista, while holding CTRL, and SHIFT, press Enter).

At Command Prompt, type in:
netsh int ip reset reset.log
Hit Enter.
Type in:
netsh winsock reset catalog
Hit Enter.

Restart computer.


If that doesn't work...
Download, install, and run WinSockFix: http://www.softpedia...inSockFix.shtml
Restart computer, and check again.

Thank you for your help. I tried all of the things you mentioned. Unfortunately none of them worked.

When I ran the command ipconfig /renew I got the following error message:

"An error occurred while renewing interface : unable to contact your server. Request has timed out."

Go Start>Run ("Start search" in Vista).
Type in:
cmd
Click OK (hit Enter in Vista).

At Command Prompt, type in:
ping www.google.com > ping.txt
Hit Enter.

In Window Explorer navigate to:
C:\Documents and Settings\your_name (C:\Users\your_name in Vista)
Double click on ping.txt to open it in Notepad.
Copy all text, and post it in your next reply.

Certainly, connection is not there.
Now....I should have asked these questions, first...
- what type of connection is it (dial-up, cable, DSL, etc.)?
- any router involved?
- any other computers on network? working connection?
- wired, or wireless connection?
- is network adapter listed in Device Manager? any errors?

Here are my answers:

- what type of connection is it (dial-up, cable, DSL, etc.)?
The connection is cable.

- any router involved?
I have a lnksys router with the problematic computer connected directly to the router. (I did the ping test both through the router and directly connected to the cable modem).

- any other computers on network? working connection?
Other computers are connected to the internet through the wireless router and work fine.

- wired, or wireless connection? See above.


- is network adapter listed in Device Manager? any errors?

Network adapters listed are:

1394 Net Adapter
Intel Pro/100 VE Network Connection

The Intel adapter has a yellow exclamation point. The device status says that "Windows cannot start thsi hardware because its configuration information (in the registry) is incomplete or damaged (Code 19).


One additional item I will mention, I have my router directed through opendns in case that matters along the way.

OK. So we have some network adapter problem.
We have to start with reinstalling it's driver.
What brand, and model of your computer? Original network adapter, or was it ever replaced?

Thanks!! That seems to do the trick. Even after a successful reboot. After many, many hours dealing with the eradication of a virus, I did not even think of looking at the network adapters in the Device Manager?!? Now I am back to the Malware forum to see if I can ensure all of those nasty bugs are gone for good!

Thanks again.
