Sorry you are having problems opting out of advanced network error search, the opt out links seem to be working from here. Something to note is you will only be able to do it from your home connection once logged into My Virgin media we have some more information here Advanced Network Error Search FAQs & Feedback
matt-h - it looks like you are already opted out so hopefully you got there before me, well it was November sorry.
Mark - I have just opted you out, please let us know how it goes.
I think there is something wrong with the advanced search - it keeps trying to search something, and I don't know why! But a new tab keeps just popping up saying advanced search error when I haven't searched anything, and then disappearing. It's getting really annoying, because the tab just opens all the time!
