Thanks, Jeff, but I had already found that on Google when first trying to get rid of the little bugger. I really only posted in case it was one that was doing the rounds again and others had seen it. The first references I found to it were in 2007 but the latest Google entries were in July and August 2009. I think it was just an unlucky browse but good for AVG, At least it found it even if it couldn't clear it on its own.
