Yes, when opening msconfig the services tab does have the services (the hide box was not checked), the DHCP Client box was checked, and the status is listed as stopped.

Click Start > Run, type msconfig and press enter.

Click the Services tab. Is there anything listed there? Make sure that Hide Microsoft Services is NOT checked!

Also, the virus seemed to have changed permissions as I took a look at startup programs (in msconfig) and noticed that there were a couple HP Printer related items, I attempted to uncheck them and it was stating that I needed to be logged on as admin (did not used to be this way).

Norton scan came up clean.

I will try that, but first, the most recent Norton scan following a complete removal with the Norton tool (performed 2x as per directions from the Norton people), and reinstall/update found the virus again in two C:system volume information\_restore...sys files. Any thoughts?

Try this: click Start > Run, type cmd and press enter.

Type net start dhcp client and press enter.

Let me know what is returned.

Hi, Norton found just the copy of the infected file in system restore. This is not a problem, since system restore will be reset anyway when we are all cleaned up. :o

Please click Start > Run, type cmd and press enter.

Type the following line and press enter.

netsh int ip reset resetlog.txt

Now restart your computer and see if the internet works.

OTL by OldTimer - Version 3.2.14.1 log created on 10112010_161803

The only connection of the internet I can check right now is the PDAnet connection. The same thing is still happening, I select connect to internet and nothing happens. It does not say it can't connect or give an error, I just does nothing. Where I'm at now there is no other wired or wireless connection to try. The PDAnet is working just fine on the other computer...

Please let me know if your internet works after the following fix. :(

Do you think it's O.K. to manually delete those two system volume information\_restore .sys files so that Norton stops picking them up as threats?

Sorry, my bad. Try this instead. Please make sure to back up your registry with ERUNT first!

Please click Start > Run, type notepad and press enter. Copy paste the following text into Notepad and save it as fixme.reg to your desktop.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AFD]
"ImagePath"="\\SystemRoot\\System32\\drivers\\afd.sys"

Exit Notepad and doubleclick on fixme.reg to run it. Allow the information to be merged. You will receive a success message, click OK.

Restart your computer and let me know how things are now.
