If I had to guess, I would say that you have an insecure script on your web server, and a hacker has found a way to use it.

1. When your CPU goes to 100%, if you go to the Task Manager and sort by CPU %, what processes have a lot of CPU usage?

2. Does it happen at the same time every day?

3. What do your web server logs say? Are there any scripts or files that are being accessed around the time that the CPU usage starts?
