I was advised to post my problem in this area:


I'm running Win XP SP 3 on a desktop. It got infected with a nasty Virus that I finally got rid of with Superantispyware.
Now I find that I can't connect to the Internet, even though the Local Area Connection is showing that it's connected. I use RoadRunner as my ISP, and called them to check everything. The Tech said that she could actually detect the Modem working. She rebuilt the TCP/IP, etc. then said there was nothing more she could do. A tech actually came by the house and said the Modem was working properly, which I know it does, because I can connect with my Toshiba Laptop. I've tried everything that I've seen on the Internet with no avail, i.e, checking to make sure IE isn't in the offline mode.

I'm wondering if there's something left of the virus in the desktop, as the laptop has no problem, which I think rules out the modem as a problem.

I've scanned with AVG and MalwareBytes and found nothing. Also repaired (rebuilt) Winsock.

Thanks for any help!

May not be anything, but I cleaned up a system the other day that had actually modified the IE settings to use an "empty" proxy that kept it from connecting.

Tools > Internet Options > Connections (TAB) > LAN Settings > make sure there are NO checked boxes

Are you able to ping websites from the command line? eg 'ping cnn.com'

Good advice other then pinging cnn.com. They(like alot of sites) block ping requests, try pinging google instead.

"ping google.com" without the "quotes".

True, was only 1/2 way through my cup of coffee and that's what was on the TV at the time... ;)

Thanks for the advice3 -- that's something that I hadn't done -- but it didn't work, either. :thumbsup:

Any other ideas? I also tried Firefox with no luck.

Here's another possibility. I ran a Network Diagnostic of my computer that can't connect and am enclosing the log:
