I am using Dreamweaver for my site, so that one file is probably OK then?
My PC got hit with some nasty malware a couple months back... I have long since eradicated it from my PC. However, during the time I was infected (probably before I realized it) I most likely uploaded infected files to my web site. Google was kind enough to alert me that my site was not meeting their standards.

As I stated, I found numerous infections on my site which I cleaned up. However, even though I've changed my account password, specific things that I know I've fixed keep returning-- things like inserted frames in htm files.
I'm thinking there is a back door that is still open somewhere on my site, and I'm trying to get help in locating it.
