Thanks for getting back to me.
I thought I had better mention I have this problem on my desktop & my Laptop. I think I have cured my Desktop which has XP on it, however I am not certain as it seems to return a little while after a spyware app has run, in this instance it was 'unhackme' (time will tell)
I reformatted my Laptop and reinstalled Win-7 to rid myself of the above problem, however after 30mins it had returned again. Could it be something to do with the boot sector, I tried 'RootkitRevealer' and the laptop just bluescreens!! Running ipconfig the DNS Servers list 3 address which seems odd as my desktop only lists one, they are
192.168.2.1 (Both machines have this & I believe this to be correct)
Crawler toolbar is not installed nor are any others.
I did the ping and the addressis - 184.108.40.206 (this is the same on both machines. I have run 'prevx' and no infections were found. I have stopzilla (paid licence) and this seems to work for a while after a scan, then it returns again when I click on a link, I can hear frantic pinging noises as Stopzilla is trying to stop it but it seems to always win!!!
I also noticed there was an additional Generic Credential. which I have now removed, this was several days ago and it has not returned! I hope this info clarifys things a bit more.
