Trojan warnings when clicking on Google search results into our MB.

[Bill Stuntz]

I haven't been able to generate any AV hits using this direct link to the post: http://mb.nawcc.org/showthread.php?1...her-model-1729

And using Google's link, the behavior is so darn unpredictable I don't know what to think.
Caution: Here's the un-obscured link:

But we're getting complaints from users, and one of the moderators reported the problem to me privately last week, with a screen shot identical to the one I posted here. The mod was using Avast, so I installed it and couldn't reproduce it last week, but I HAVE been able to intermittently reproduce it last night & today from the complaining user's link. I don't know what AV anyone else is using - they haven't replied to my question.

P.S. The screen shot I posted was from MY computer last night. And the AV hit was on my HOST computer's screen when I followed that Google link in my VIRTUAL XP. I disabled the Avast on the HOST, and the message showed up again from the VM's Avast.

I'm fairly sure our MB is NOT infected, but it might be difficult to convince our visitors of that.
