I am running a standalone installation WP 2.6.1 using a hosting service. It's a simple blog, running a blog.txt theme. For some time, when I enter the site (even without being logged in), a message pops up asking if I want to allow a Flash from several sites (shefler.net and diwani.ca) - the search has yielded info that these are, in fact, viral.
Now, when I look at the source code on the main page of a blog, there is, indeed, a block of code embedded before !DOCTYPE html PUBLIC section. How can I remove it? It does not seem to be any of the templates in the theme editor.
Thanks in advance
