Snapshot pro taking up all ram on server?

Hi,

My website was down and I was notified by the host that the issue is Snapshot Pro taking up all the ram on the server. So I finally managed to get into the wp-admin backend for 5 minutes to disable it. But now it’s disabled the website is still running slow or not loading at all

Is there a chance the processes are still going or something? How can I stop them?

Any help is appreciated, thank you
