Google Checkout module for ZC 1.3.x (beta)

[Webskipper]

I have done a search, but cannot find this problem mentioned, although I ask forgiveness if it is there and I just am not seeing it. I presently am running Zencart 1.3.8a with the corresponding Google Checkout module. There may have been a securty patch notice sent which I ignored, but someone has managed to get into my store and add spam in the way that the bottom line of my Zencart has a line of spam for two popular men's pills and all my emails going through my Zencart has the same for the subject line and the email from lines. Where does one edit this information out, and how can I prevent it from happening again. It has already scared away customers, so help and forebearance would be appreciated.
