Assuming you're not using a wireless where someone can poison your ARP cache and redirect you, contact your ISP and tell them what's going on. IMO you have a proxy feeding you certs. If that's the ISP, their proxy servers may be misconfigured or compromised.

Also run virus and malware scans, including A squared free, for installed proxies or other malware.

If you use any special software for secure signins to work or other sites, check with the site's help desk.

Finally, send an email to spoof@Ebay.co.uk or ebay.com. It may not help, but can't hurt. In the meantime try using another PC for logins to sensitive sites until you get this resolved.

Only Ebay cert not 'working' or every SSL cert??? try other secure sites as well & check...

With NTL you have to go through a proxy I have tried various ones but each time I get the duff certs.

Something is definitely wrong here. You are right to be suspicious.

I can't tell if this is an MITM attack, or malware on your computer, or DNS poisoning that is taking you to the wrong site. I would guess that DNS problems are the most likely.

You might check whether you have a hosts file with a bad entry for securepics.ebaystatic.com.

That statement seems to be at odds with the setup instructions on the NTL web site as shown in the screen capture below.

For what it is worth, securepics.ebaystatic.com appears to be operated by Akamai, and with the load balancing tricks that Akamai does, you could be going to a totally different login server than someone from the US, and what you are seeing may be a temporary problem with the Akamai DNS (it has happened before).

Something could be inserted between VM and net. However, it is far more likely that the problem is at your ISP - either their DNS server or their web proxy server.
