Hi everyone, I had (until a few hours ago) avast installed on my machine. I thought I might try running a trial copy of nod32 since things had been running more sluggishly than normal these past few days so first off I downloaded the avast uninstaller aswclear.exe that was linked from the nod32 site and mentioned in a thread here a few days ago.

I suppose I really should have uninstalled avast via add & remove programs before running the uninstaller aswclear exe but I was impatient. So I simply disabled avast's self defence system, ran the uninstall utility and then installed the nod32 trial before restarting.

I noticed I had no internet connectivity once my machine had booted back into windows xp. I can ping over the internet and lan via ip address but a ping via computer name or website address just returns an error a ping to my computer name also strangly enough returns a reply from ::1:
I can ping the dns servers for my isp and manually defining the dns server under the tcp/ip v4 settings doesnt make a difference.

On a side note all other computers on the network are completly unaffected and can access the internet with no trouble. My computer can also access the internet without any troubles if I boot off my ubuntu partition, I'm actually typing this from windows xp at the moment since I can access web sites by typing the server ip into the address bar.

Help is much appreciated, thanks
Jacob

You uninstalled avast! totally right, so you didn't do anything wrong.
Try download and running WinSockFix and see if that makes a difference:
