I got everything working now. Got access to SSH (not sure how, but think my hosting provider did something). Identified the infected files. Did a full malware scan and then full reboot. CPU seems normal as of now.
EDIT: CyberPanel support also did an upgrade do 2.3.8.
Does anyone has problem restoring from the one click backup?
I am trying all day today it was very very slow on transfer and now i got error
Error message: [“Failed to restore backup. Error ‘dir’. [404]”]
