Trojan:JS/Iframe.BU uncertainty

[DavidF]

I'm wondering if anyone else had come across this one?
I've done a bit of searching but the results are sketchy.
The client owns a website which Norton flagged as dangerous, they clicked the "Do not show me this warning again" message and haven't been able to access it since. (IE8 on vista)
I tried it on FF/Win7 with MSE, MSE flagged it automatically and quarantined it.
Out of interest I also tried it on my phone (Samsung Galaxy) and it failed to load.
Their website designer (who seems legit) tried it on a mac and 2x windows machines without issue.
The site appears to be hosted by Go Daddy.
It appears to me to be a compromised site but equally might be a false positive.
Any experience with this one appreciated.

It's not one I've come across personally David.

Would you mind pm'ing me the link, and I will have a look at it my end, with various av's and computers. See if it triggers them.
