Hello,
I can help you get this secured and up to date today if you like. Most likely your host will be able to provide a bit more information, and we can use this to identify the problem script and resolve it.
If this is on your own server, even better, but if not, I can work with your hosting provider and do everything possible to get this secured and fixed for you :)
If you'll look at my profile (click the link directly, don't go by what they show in this specific bid), you'll see 100% project completion, 100% positive (5 star) feedback, and a link to my own site where I've done the same for better than 10 years now. Your project will be completed with the same diligence and persistence. Your task will be completed within the advertised period of time, and be given everything needed to be done right.
I look forward to hearing from you and working with you on this project.
Tom Whiting
