I have an interesting problem. I have cleaned a computer (Windows XP- SP3) of all of it's viruses and malware (using AVG in another computer, then ComboFix, SDFix in Safe Mode, and manually cleaning the registry and checking Services). I have also uninstalled ZoneAlarm, and restored the TCPIP stack with WinsockFix.
After the problems were all gone now no matter what I do after booting, any web browser only works for about 5 minutes, then when you click to go to another page after that it waits for a bit and then just goes to a blank page and says done in the status bar. I can still go to https pages (port 443) and email and chat programs all work, only port 80 dies.
I ran netstat -ano in a cmd box (TCPView also) and I can watch the SYN go out, but nothing comes back (i.e. it is supposed to come back ESTABLISHED).
I also ran Process Explorer and saw nothing out of the ordinary.
I know the hardware is good as I booted to an Ubuntu CD and everything stayed working for 30 minutes.

I had this on another machine 2 weeks ago (fixed it with Ubuntu!), so I think I'll be seeing it again and would rather not have the only fix being to install Windows to a new directory.
