@sanju your ssrver has been infected by cpu monero cryptominer. Do you have a snapshot of this server or you need the info you have on it?
There is no automatic removal of this malware becuase we cannot know to what extent your server is infected. The manual option of removing and disinfecting would take longer and still would leave traces of the malware or backdoor.
Best option is to install an earlier snapshot ot the server or do a clean install
