McAfee found an "Adware Keen" virus on my PC. Deleted all those files. Then ran Pest Patrol and Spybot and the machine looks clean.

Problem is, I can connect to the Internet, but I cannot resolve any IP addresses or URL's. Brought the machine into work and connected it to the network and it behaves the same way even with a static IP address.

Did the virus corrupt the TCP/IP stack? What could be the problem?

What kind of connection? Dialup?

Have you looked at your HOSTS file?

You say you can't resolve any IP address or URL and I just want to clarify something. Can you ping anything using just the IP addy?

Doesn't matter if you use dialup or ethernet, same result. When I get connected, I can ping hosts by IP address but if I try to ping by name it doesn't work. Browser is totally hosed because of this. No DNS resolution whatsoever.

Also, Pest Patrol now doesn't work. If you try to start it, it says "...encountered an error and has to close...". I tried reinstalling but got the same result.

Did you check your HOSTS file?

What about it? I recently copied a new hosts file to the disk, but I didn't put in where Windows would expect to find it.

Are you saying that perhaps the virus somehow corrupted the hosts file?

It's possible, lots of spyware does that.

But I don't think that's it. I just think you should try it because it's so easy.

I suspect you'll ahve to re-install your TCP/IP and network connections and such.

I work in an IT support group and one of the Windows techs is trying that right now. He's doing some sort of "Repair" operation.

I quit working on MS stuff when 95 came out. Of course everyone "needed" it, but it broke everything, especially the more expensive software like MicroCadam and AutoCAD (I worked for a CAD/CAM support group). Right then and there I decided to focus more on Unix. Still no guru, but don't have to work full time on Windows either.
