Hi noz,
This is the golden tip. After cleaning out the newdotnet with x-cleaner micro from here:
http://www.xblock.com/download-freeware.php (Do not forget to bckup the registry), I rebooted the computer and lost both the browser and mail internet connections. Happily the man had Win XP SP2 indstalled. So went via start to the commandline prompt and give in the magical "netsh winsock reset" (without brackets), and instantly after the enter it got the connection reset and working again.
So I can state after what I have experienced to-night, that this works beautifully. Chapeau "noz", you are a promishing malware fighter. Thanx. Else I would have used lspfix from a mem stick.
Open my computer, double click, and run from that partition.
But again "netsh winsock reset" is the easiest and most elegant of varyous solutions lest on XP SP2.
Good work noz, I remember the victim of Newdotnet after he saw his Internet connection back. "How did you do that?"
I responded: "Just some magical word from a very good anti-virus forum". The nicest thing is the big smile in the eyes you get. Great feeling, man. Most awarding.
