[befuddle]

I spotted that my own code site was hacked this morning.

The site appeared fine but I spotted what appeared to be a 1x1 pixel missing image on my home page only.

Assuming that I'd messed up the template slightly I viewed the source code to see lots of viagra related references and links to another site.

I've removed the header code but I'm concerned that it may re-appear as I don't know how it got there in the first place.
