Website is being redirected by malicious trojan/virus

Hello,

So I’ve tried working with my host provider to find the cause of why my site is being redirected. I updated to an earlier date when I know I was not having any issues like this. It has not worked. Everytime I log in to my dashboard I’m being bounced right out. I can’t click on anything within the menus. This is really frustrating. I know I have an option of uploading my backup, but there is so much content that I will lose. I’m generating content, and my backup goes up to July 21st. I need some help, and future guidance on how to protect my site in the future.
