Spoke to my friend who works at symantec last night, he said it has nothing to do with Showkase. My server is a rented co-lo (set up by another buddy who also works in internet security who just upgraded the hardware), he says TrendMicro will put up to 200 servers on the malicious dangerous list if anyone with a similar IP is naughty (paraphrasing as I am a photographer where a lot of my friends are computer nerds)
After submitting my report TrendMicro has now taken me off the dangerous list and I am good to go, sorry for the panic! My web site has only showkase site and a virtual tour on it at the moment and assumed that caused my site from being displayed.
Let me know when you have seen this and I will delete the whole thread, or feel free to do it yourself as I would not like people to think your awesome product would cause any harm. Keep up the great work!
