Apologies if you couldn't get on this blog yesterday and instead got a large screen telling you that it was dangerous to go on the site. So did I.
This morning I googled the problem and discovered that my blog was fine and didn't contain any nasty viruses. The problem is with blogarama.com.
I had put a link to blogarama.com, on the right hand side bar, ages ago. Apparently they have been hacked and it was only dangerous if someone clicked on the link.
I have removed the link so all is well.
Apparently this is happening to 1000's of blogs so if you have the link on your blog then I suggest that you remove the code.
